Agenda 01/10/2017 Item #16C 1 16.C.1 01/10/2017 EXECUTIVE SUMMARY Recommendation to approve the Rank Order of professional engineering consultants for Request for Proposal 16-6639, "Variable TDS Reverse Osmosis Conceptual Design," Project 70104, and direct staff to begin negotiating an agreement with the number one ranked firm,CH2M. OBJECTIVE: To obtain professional engineering design services for the Variable Total Dissolved Solids (TDS) Reverse Osmosis (RO) Conceptual Design Project. The resulting 30 percent design will be used as a basis for a future design-build project that will reconfigure the North County Regional Water Treatment Plant (NCRWTP) so that it can treat groundwater of varying TDS conditions. CONSIDERATIONS: The NCRWTP's RO wellfield consists of 20 brackish water wells. Four of those wells currently exhibit TDS concentrations above the 6,000 milligrams per liter(mg/L) level that can be treated by the current RO process. As a preemptive measure, staff recommends obtaining a 30 percent design for process changes that will treat a wider range of groundwater conditions. Should wellfield conditions continue to deteriorate, the ultimate design-build solution will be initiated. Project deliverables include: A. capacity study; B. determine impacts on capacity with varying TDS concentrations of 3,000 mg/L to 20,000 mg/L from the current Hawthorn Aquifer, and potential Avon Park Aquifer sources; and, C. provide options to remediate those impacts and develop a 30 percent design for the NCRWTP RO treatment process of the most cost-effective option for modifications to handle increased TDS concentrations in the order of 3,000 mg/L to 20,000 mg/L, while maintaining 8 million gallons per day of production capacity. Staff issued Request for Proposal (RFP) 16-6639 on May 12, 2016, sending out 1.666 notices. Fifty-two firms downloaded the RFP package. The County received three proposals on June 30,2016. On August 25, 2016, a selection committee scored the three firms based on an evaluation of their proposals. By consensus the selection committee ranked the firms as follows: 1. CH2M 2. Tetra Tech 3. CDM Smith Staff requests authorization to begin contract negotiations with the number one ranked firm, CH2M, and, in the event that an agreement cannot be reached, continue negotiating with the remaining firms in the order ranked above. FISCAL IMPACT: There is no fiscal impact associated with this action. The source of funding for the future contract is available in, and is consistent with, the FY2017 Capital Budget approved by the Board of County Commissioners September 22, 2016. The source of funding is the Water User Fee Fund(412). LEGAL CONSIDERATIONS: This item is approved as to form and legality, and Packet Pg.549 16C.1 01/10/2017 requires majority vote for Board approval.-SRT ., GROWTH MANAGEMENT IMPACT: This project meets current Growth Management Plan standards to ensure the adequacy and availability of viable public facilities.

The Es Consultant, at a minimum, must achieve the requirements of the Specifications or Scope of 03 Work stated. Brief Description of Purchase a) 1) Provide a conceptual design of modifications to the reverse osmosis (hereinafter, "RO") 0 treatment process at the North County Regional Water Treatment Plant (hereinafter, the "NCRWTP") of the most cost-effective option to handle increased total dissolved solids (hereinafter, "TDS") concentrations in the order of 3,000 to 20,000 TDS while maintaining 8 E MGD of production. The conceptual design shall include an initial opinion of probable construction cost and schedule based upon the design concept. cu 0 2) Provide a proposal to: a. Perform a capacity analysis to determine impacts on capacity with varying TDS v� concentrations of 3,000 to 20,000 TDS (from the current Hawthorn aquifer and potential Avon Park aquifer sources), provide options to remediate those impacts. b. Provide a 30% design criteria package plans and specifications for the NCRWTP and all m associated components for the purpose of implementing the future design-build phase of the project. A final opinion of probable construction cost and schedule shall be included. ti A selection committee will select three contractors with the best qualifications, conceptual N designs and proposals for capacity analysis and 30% design criteria package. 0 If awarded, a contract to provide these services will be effective on the date contract is approved by the Board of County Commissioners (herein after, the BCC), signed by all required `' parties and filed in the Office of Records and Minutes. The anticipated contract term will be for con the period of 12 months. CD As is more fully explained in Section 11, Subsection E of this RFP, an award, if made, will be made to the best overall proposer(s) whose proposal is most advantageous to the County, taking into consideration the evaluation factors set forth in this RFP. The County will not use any other factors or criteria in the evaluation of the proposals received. 0 Background The Collier County Public Utilities Department constructed the NCRWTP in 1993, at the time the Plant had a production capacity of 12 mgd utilizing a membrane nano-filtration technology. In 1999, the NCRWTP was expanded to include 8 mgd of production capacity utilizing low pressure reverse osmosis technology. Soon after construction of the 8 mgd expansion, a problem with four wells producing high TDS water was discovered. These wells are located directly to the west and just east of the NCRWTP. Studies have been undertaken by various firms and it has been determined that a salt plume is migrating east towards the heart of the North Reverse Osmosis Wellfield. The high TDS wells are therefore unable to be treated by the RFP CCNA Template_01202016 RFP_CCNATemplate 4 Packet Pg. 556 16.C.1.b existing treatment processes in place. Each of the wells has the capacity to produce a high quantity of water; therefore, the Department desires to have installed additional treatment technology in order to continue to utilize these assets. In 2005, CDM was commissioned to do a feasibility study for constructing this additional technology. A copy of this report "North County Regional Water Treatment Plant High Pressure Reverse Osmosis Feasibility Study" is available from the Project Manager. In 2006, Carollo Engineering Firm was hired to perform pilot testing of various membranes that could be utilized to treat the high TDS wells. A copy of the preliminary report from that study is available from the Water Department by contacting the Project Manager. In 2007, Hazen and Sawyer completed a report on evaluating the odor control dispersion model, titled "Performance Evaluation of Degasifiers and Odor Control Facilities for the North County Regional Water Treatment Plant". A copy of this report will be available from the Project Manager. In 2007, the Water Department 0 hired Boyle Engineering to complete a study on the inter-stage booster system on the existing Reverse Osmosis Trains; the report from that study, is titled "North Collier County ROWTP o Inter-stage Energy Recovery Turbine Evaluation". A copy of this report is available from the N Project Manager. In 2009, HDR Engineering completed a Preliminary Design Report titled o "North County Regional Water Treatment Plant High TDS Reverse Osmosis Expansion" which considered a High TDS RO 2 MGD expansion. A copy of this report is available from the Project Manager. ccU) The capacity of the NCRWTP reverse osmosis (RO) treatment process may change as influent characteristics of the feed water deteriorate over time. The NCRWTP presently has a capacity a� of 8 MGD (2 MGD per RO skid). Detailed Scope of Work The Contractor, at a minimum, must achieve the requirements of the Specifications or Scope of Work. Additionally, Proposers may also propose alternate solutions to achieve the 0 requirements of the Scope of Work. U The following outlines some of the tasks anticipated to be performed by the contractor and c°n considerations in further refining tasks. °; CO 1. The selection committee shall evaluate the contractor's qualifications, Conceptual Design and Capacity Analysis/30% Design proposal based on the criteria which follows: N a, a. Capabilities and experience of the firm (20%): Contractor shall demonstrate the firm's understanding of the project, the capability to perform required services including proximity of key staff and the firm's ability to meet overall project schedule as outlined in this RFP. Identify the firm's key personnel for these services and submit their resumes. Include a project team organizational chart a> showing key personnel for both the firm and all planned sub-consultants. Provide information on the experience of the firm and/or key personnel as it specifically relates to a water project design of this nature. Provide references from similar projects. RFP CCNA Template_01202016 RFP_CCNATemplate 5 Packet Pg. 557 16.C.1.b b. Record of similar services (20%): Demonstrate recent successful work for similar projects completed by the firm and identify the client, scope of the firm's services, facility size and the date services were completed. c. Conceptual design (30%). d. Capacity Analysis & 30% Design proposal (30%). N 2. Tour of existing facility and interview treatment plant operations staff. This step will allow 2 an understanding of the conditions at the existing facility as well as any challenges being experienced in the operation of the facility. 3. Obtain and review record drawings for the facility. Provide a process flow schematic which clearly identifies the key process units combined with critical components along each process flow path which results in feed-water ultimately becoming product-water. Some critical components will be associated with power supply and instrumentation and not simply treatment units and pumping equipment. This will allow incorporation of a 0 reliability assessment for the facility. n m 4. Review and summarize the complete range of operation for all key components. For example, review all pumping systems with respect to pressure-flow combinations cn available between minimum and maximum speeds for which the pumps potentially might F- be operated and not just the design points. Consult membrane manufacturers to obtain their anticipated performance over a range of conditions, such as pressure, feed water (13 quality, and typical aging of the membranes. 5. Obtain current operation conditions with regard to each process train, such as pressures, flows and water quality. Where available, obtain similar data during the life of `V the facility. Provide an analysis of available operation data and develop any correlations o between performance, production, water quality, and hours of operation which can be extracted. It is expected that some sorting of parameters will need to be done using anticipated performance expectations per manufacturers in order to normalize data to some extent. It is not the intent to develop exact relationships, but a model with a c� rn reasonable correlation to observations. In the event that these observations are outside of ranges expected, based on manufacturer anticipated values, then this may require ca further investigation as to why. N 6. Investigate the potential solutions for handling water quality in the 3,000 to 20,000 TDS study range. Alternatives will be developed for potentially making a transition from the current system to these conditions. It is anticipated that alternatives would be developed y which would result in trade-offs between various performance criteria such as volumetric capacity (gpm of product water) as well as percent recovery and total energy required per gallon of water produced. 7. Each of the alternatives proposed shall accept feed-water conditions in the 3,000 to 20,000 TDS range. The ability to either phase implementation, or to include sufficient "turn-down" over the range of conditions, will be considered and evaluated. 8. The conceptual design shall incorporate the following requirements: RFP CCNA Template_01202016 RFP_CCNATemplate 6 Packet Pg. 558 16.C.1.b a. Process automatically adapts to changing feed-water conditions. b. One PLC dedicated to each skid. c. Instrumentation and controls aligned with PUD SCADA integration policy; see attachment. d. Address any electrical upgrades required for the proposed modifications. e. Address impacts to pre-treatment, post-treatment, degas and odor control caused by the proposed process modifications. a, f. If necessary, provide recommendations of replacement of systems which may '_ not be directly at risk due to a change in feed-water quality, but simply looking for o an appropriate time to upgrade those systems, which logically should be considered when other upgrades are programmed into the overall schedule for a removing systems from operation. 0 g. Provide operational cost estimate of the proposed conceptual design and a 0 financial model that predicts optimum membrane cleaning and membrane y replacement times. o h. Provide an initial opinion of probable construction cost and schedule based on E co the conceptual design. a a) IL' 9. The capacity analysis shall address impacts on capacity with varying TDS concentrations of 3,000 to 20,000 TDS (from the current Hawthorn aquifer and potential CDCC Avon Park aquifer sources) and provide options to remediate those impacts. o I- 10. The 30% design criteria package shall include a detailed listing of components which 0 would need to be replaced as well as timing for such replacement, allowing costs to co FE begin to be more accurately assessed. In situations where phasing of improvements would seem a more appropriate means of implementing an alternative, then the relative age of those components at such time would be estimated and compared to timing when v they, under normal operation, may otherwise be programmed for replacement. For example, it might be found that membranes might be retained for some period of time, -- over over which production (gpm) may gradually deteriorate, before scheduling their replacement early, but with a membrane with performance characteristics more .3 appropriate with the future conditions. The driving factor very likely may be in pumping •o equipment or other components, either independent or in combination with membranes. cn The 30% design criteria package shall also include a reliability analysis of critical co components, a final opinion of probable construction cost, an updated construction schedule and an updated estimate of operational costs based on the 30% design. up N N It shall be understood and agreed that any and all services, materials and equipment shall comply fully with all Local, State and Federal laws and regulations. 3 cs County's Responsibilities a County responsibilities include: as 1.

The nanofiltration (NF) system softens water from the shallow Tamiami Aquifer and has a rated capacity of 12 mgd. The brackish water reverse osmosis (BWRO) system was added in the late 1990’s and desalinates water from the deeper Lower Hawthorn Aquifer, which is part of the Floridan Aquifer System. The BWRO system has a rated capacity of 8 mgd. It contains typical treatment processes for a brackish groundwater system, including sand separation, cartridge filtration, sulfuric acid and scale inhibitor addition for pre-treatment, two-stage single-pass reverse osmosis with inter-stage boost energy recovery for main treatment, and degasification, chlorine disinfection and chemical additions for post treatment. The NF and RO permeates are combined prior to degasification. Also, the NF and RO concentrates are combined, re-pumped and discharged into an on-site deep injection well system. Exhibit II-a depicts a simplistic process schematic. Soon after startup of the BWRO system in 1999, five wells (e.g. RO-001 through RO-004 and RP-006) experienced rapid increases in salinity. Within two years (2000-2001), total dissolved solids (TDS) levels in the EXHIBIT II-a NCRWTP Process Schematic II-2 wells went up from 5,000 to 20,000 mg/L, and that water could not be treated with the existing BWRO system. The source of saline water was studies and was believed to be underlying more saline aquifers, with conduits to the production zone, and not related to upward migration from the deep injection well system. The wells are completed at a depth between 700 and 900 feet below land surface, have short open-hole interval in a high transmissive formation, resulting in well productivities of around 2,000 to 2,500 gpm. Efforts were made to rehabilitate well RO-006 by back plugging part of the open hole to stop salt groundwater inflow, at the sacrifice of production, however these efforts were not successful. Therefore, the wells have been largely unused. Since 2002, additional, less saline wells were added further east to maintain the production capacity of the WTP. The wellfield information from Collier County was showcased in a recent paper presented at the 2015 FSAWWA conference in Orlando by one of CH2M team members (Exhibit II-b on following page). The paper also presented other Floridan wellfields with similar water quality issues and best practices described to overcome the issue. Between 2005 and 2010, several consultants studied the TDS increases in the wellfield as well as different aspects of the plant, however additional membrane treatment technology to treat saline water was not yet implemented by Collier County. In the late 2000’s the BWRO trains were fitted with inter-stage turbine energy recovery devices (ERDs) to preserve energy and increase the source water TDS level that the RO trains could treat. This project envisions the development of a preliminary design for the most cost-effective solution to handle variable TDS water, ranging from 3,000 to 20,000 mg/L from the current Hawthorn aquifer and potential Avon Park aquifer while maintaining the plant rated capacity at 8.0 mgd. At this stage it is uncertain how the raw water quality will develop in the wells under more continued production. Therefore, Collier County is looking for a solution which is affordable, flexible, adjustable and implementable in phases. It is envisioned that the preferred solution will be implemented via a future design-build phase of the project. The preliminary design will be used as part of the design criteria procurement package. Collier County’s aim is to continue using the existing infrastructure, modified to suit the high TDS water in their productive wells, while also capable of treating existing TDS water efficiently, and either limit further migration of bad quality water to other production wells or clean up the area of bad water quality altogether. Since 2008, CH2M has been working successfully for Collier County on several upgrades projects at the NCRWTP. These projects started with the evaluation and conceptual design for the addition of inter-stage turbine ERDs on the existing RO trains in conjunction with Florida Power & Light. More recent improvement projects at the CRWTP include design and services during construction (SDC) of higher capacity finished water transfer pumps, design and SDC of new degasifier drop pipes, evaluation of WTP post-treatment degasification efficiency, design of a liquid fluoride storage and feed system, and the refurbishment of existing NF trains (ongoing). Through these projects, CH2M has become very familiar with the process equipment and infrastructure at the NCRWTP, the existing operations and maintenance and specific pitfalls at the existing site. Also, following the instructions on page 9 in the Request for Proposal, CH2M visited the NCRWTP site on June 6, 2016 to become even more familiar with local conditions. Implement the most cost-effective and flexible treatment solution to handle variable TDS raw water while maintaining existing production capacity at NCRWTP. This enables to use of the highly productive – though saline – on-site wells with the intent to limit the migration of bad water quality to other wells in the wellfield. Project Objective II-3 EXHIBIT II-b CH2M Understands Water Quality Degradation in the Floridan Aquifer Collier County North and South RO systems were showcased in a 2015 FSAWWA paper “Salinity increase in the Upper Floridan Aquifer Wellfields in South Florida: What have we learned and how do we plan new systems?” by one of CH2M team members. As part of this paper, Collier County’s well water quality was collected and analyzed for trends and abnormalities. One section in the paper regarding the Northern wellfield is summarized below: “Wells RO-001 through RO-004 and RO-006 at the western end of the wellfield which are producing from the Lower Hawthorn Aquifer experienced rapid increases in salinity shortly after they were placed into operation. Chloride concentration of water samples obtained from these wells during 2000 and 2001 ranged from approximately 2,000 to 3,000 mg/L. Chloride concentrations in these wells increased to between 6,000 to 10,000 mg/L within two year of operation. A total of 19 additional production wells have been added to date to increase raw water supply capacity to the RO WTP. Individual well yields in the wellfield generally range from 500 to 700 gpm with chlorides concentrations ranging from 850 mg/L to 3,000 mg/L. In the Northern wellfield, 21% of the wells have seen a chloride increase of 5% or higher during each 12 months of operation. The ‘bad’ wells are 001, 002, 003, and 004 and to a lesser extend 009…” The graphics depicting combined raw water chloride trends of both Collier County’s wellfields (left) and individual chloride increase in each northern well (right). Wells 002, 003 and 004 saw a significant chloride increase with current levels around or just above 10,000 mg/L. This salt increase is however not consistent across all constituents. Whereas chloride, TDS, magnesium, sulfate and sodium almost quadrupled within that period, other constituents (not shown in graphics) like calcium and bicarbonate only less than doubled and again others like fluoride, strontium and barium hardly increased at all. This in-depth understanding of water quality degradation and trending is important for the solution developed for Collier County to treat groundwater with variable TDS levels. Work Plan Interactive Workshop Decision Making Approach CH2M uses an interactive decision and design workshop approach in its preliminary decision-making and subsequent design processes. This interactive workshop approach is used to:  Solicit client direction  Rapidly sort through options  Evaluate technical, economical, operational benefits  Gain input from national experts and relevant project experience  Solidify optimal treatment approach for the variable TDS treatment system  Develops and documents a sound and defensible decision approach II-4 Workshops will be conducted with the County throughout the process selection and preliminary design process to review treatment options, consider non-cost criteria, and review projected costs including construction, operations and maintenance (O&M) and overall lifecycle costs of different options. Process Selection Tools The CH2M team has extensive experience with treatment process analysis, and multi-variable benefit–cost analysis to select treatment process schemes, including process evaluation and testing, cost-benefit analysis of selected process, process selection, and design and construction. We often use a pair- wise comparison to help develop and rank criteria that are most important to the County at the planning level before implementing design. The analysis will incorporate a life cycle analysis to ensure that O&M cost is included in the design selection. Non-cost criteria should consider reliability, O&M considerations, and possibly environmental considerations that may drive selection of an option that is not necessarily the lowest cost. Design, Costing, and Optimization Tools CH2M HILL’s proprietary technology and costing models effectively capture our best practices and will help Collier County quickly and cost-effectively find a true optimum solution. We have developed and successfully applied a variety of simulation and optimization modeling tools that quickly and accurately estimate capital, O&M, and life-cycle costs, treatment performance, and system control. These one-of-a-kind models include CPES™ (our CH2M Parametric Cost Estimating System tool), Replica™ (our dynamic treatment simulation model), Source™ (our water treatment mass balance tool), Preview™ (our facility visualization tool), Voyage™ (our complex decision support model), and SI Port™ (our sustainability tool). We have linked major membrane treatment manufacturer projection software into our process models to ensure that we use the most-up-to-date membrane performance information. Specifically, this project will heavily use CPES which is a proprietary conceptual design and cost estimating tool that generates quick, accurate, and detailed cost estimates at the conceptual stage of the project. CPES costs are based on general arrangement drawings derived from real projects and project specific process design criteria. Using algorithms built into the model, the system generates project-specific facility designs and construction and lifecycle cost estimates. Compared with traditional conceptual estimating techniques, CPES yields a much clearer picture of the project’s unique scope in a fraction of the time. We will use CPES to quickly develop detailed comparative construction, O&M and life cycle costs for candidate alternative Component ranking with cost-benefit analysis will highlight optimum treatment solutions. Preview™ will help Collier County visualize different treatment options early during conceptual design. These models are refined during subsequent conceptual design. Replica™ will allow an analysis of all combinations of water quality and treatment options in a virtual water treatment environment without the need to use constraint that may only help find apparent optimum solutions.

Preview™ will be used to help Collier County visualize the different options developed in CPES before final selection. Replica™ will be used to model different combinations of source water quality and treatment process options to determine the true optimum lifecycle cost options without the need to make estimations to simplify the analysis that can find apparent optimum solutions instead of true optimum solutions. Integrated process selection and design development with advanced design tools such as these will be used to find the best solution. Task 1 - Project Kick Off and Information Review This task provides the foundation for the project. It will confirm Collier County’s project objectives, define the analytical framework for developing and evaluating alternatives and guide the collection, review and summary of information. Gaps in information will be identified and actioned in coordination with Collier County. An example of information, that is not yet available but would need to be collected, is the current (extensive) water quality data of the affected wells beyond conductivity and TDS, in particular the constituents causing membrane scaling/fouling. Key sub-tasks for this task include the following:  Hold kick off meeting to: o Confirm project objectives, scope, schedule, project team and communication lines o Develop evaluation criteria for alternatives evaluation o Receive and review requested information from wells and treatment plant  Review information received and analyze, in coordination with the membrane vendor, normalized membrane performance data to determine trends or correlations between performance, production and water quality  Summarize findings in an existing information review technical memorandum, provide gap analysis and recommend on gathering additional data  Conduct review meeting and provide meeting summary Task 2 - Facilities Visit and Condition Assessment This task will build on CH2M’s existing knowledge of the RO system to create a better understanding of the background of the TDS issue and facilitate an initial dialogue between parties on potential strategies to mitigate variable TDS water. Also, it will provide additional hands-on information of existing facilities to verify suitability for continued use with the variable TDS water. An example is the verification of appropriate pressure rating and material compatibility of the pipework, pumps, and pressure vessels to treat water with a significant higher TDS of the affected production wells.

This assessment will be limited to review of existing design documentation and visual inspection covering assets that are readily and safely accessible. CH2M desalination process engineers will analyze system operating data trends to estimate remaining existing membrane element life. Additional testing to verify conditions, performance, and/or specifications will be identified and shared with Collier County. Key sub-tasks of this task include the following:  Initial visit by CH2M’s project leadership team to existing WTP focusing on overall condition and reliability of facilities, and determine vulnerability and single points of failure  Interview WTP staff  Detailed visits by discipline engineers to confirm specifications and assess condition of existing facilities: o Production wells o Well surface facilities and transmission o RO treatment facilities and concentrate surface facilities o Blending and post treatment facilities o Concentrate injection well o Associated electrical infrastructure o SCADA system and control loops  Summarize findings in a condition assessment technical memorandum and provide recommendations for additional testing  Conduct review meeting and provide meeting summary Task 3 - Best Industry Practices for Treating Variable TDS water The purpose of this task is to establish best industry practices of treating variable TDS water by collecting information from the wide range of CH2M project experience, strategic partner experience and other utility experience with similar water quality issues and treatment as Collier County. This includes collecting information on treatment which has not worked effectively or has been previously discarded by the County. Contact will be made with equipment manufacturers which are active in this market segment including new and emerging technologies that are anticipated to mature within the project timeframe. Since the previous studies were executed for NCRWTP variable TDS project, between 2004 and 2008, membrane treatment technology has further improved with the following major global developments: 1. More energy efficient, higher rejection membrane elements 2. Different type and more efficient energy recovery devices 3. Operational methods different from the typical continuous reverse osmosis to provide low energy, high recovery, and flexible treatment solutions, including forward osmosis and closed circuit osmosis Several global clients have trusted CH2M team members to provide them with cost-effective, innovative solutions for variable water quality systems.

Desalitech RO batch process to automatically adjust to variable feed TDS while producing low TDS permeate II-8 Task 4 - Definition of Variable TDS Future Water Quality The purpose of this task is to develop the most important design criteria for the variable TDS treatment system, the variability of the future water quality. This requires extensive water quality data from individual wells, a thorough understanding of the system operations and water degradation projections guided preferably by a soluble transport three dimensional (3-D) groundwater model. Key activities include the following:  Establish existing operations of the wellfield and treatment system and discuss future options for operations. One key discussion will be the main purpose of the affected wells; e.g. permanent operation, semi-permanent with main operation in peak season or just standby.  Develop projections of relevant water quality parameters for each well or each group of wells (TDS, chloride, sodium, chloride, sodium, strontium, barium, sulfate, carbonate, gross alpha)  Develop raw water well blending scenarios  Develop future water quality technical memorandum  Hold review meeting and provide meeting summary Task 5 - Treatment Alternatives Evaluation for Handling Variable TDS This task covers the development of different options to deal with variable TDS, including operational and capital solutions. From experience, it is expected that a combination of several operational measures can provide treatment of raw water up to a certain TDS level without requiring capital expenditure. For instance, by changing to more energy efficient, high rejection membranes, reducing BWRO recovery and making chemical addition changes, it can be expected that raw water up to around 10,000 mg/L TDS may be treated with the existing system without making holistic infrastructural changes at the NCRWTP. An insight into the feasibility and effect of each candidate solution is important to develop a strategic plan to overcome variable TDS water. The options may include phasing based on actual needs to minimize high capital and operating cost expenditure initially and may include trade-offs between various performance criteria such as treatment capacity, treated water quality, system recovery, chemical and electricity use. Key sub-tasks include the following:  Develop operational solutions: 1. Limit variable water quality: a) Back plug or acidify production well(s) b) Abandon well(s) Based on previous work, CH2M knows that water quality variation in the Upper Floridan Aquifer can be caused by vertical or radial migration conduits induced by aquifer stresses caused by well water withdrawal. The conduits include abandoned wells, fissures, cracks and fractures with a direct or non-direct connection from more saline aquifers or seawater to the well borehole, as illustrated below. The trends of various water quality constituents may vary and depend upon the nature of the recharge water:  Ion strength, conductivity, chloride, sulfate, magnesium and sodium follow the same general trend as TDS and can be predicted by a groundwater model  Calcium, potassium and alkalinity may have a less steep trend than TDS  Strontium, barium, gross alpha, and silica may not have a trend at all  Trends in the last two categories may be obtained by reviewing historical data from Collier and other Upper Floridan wellfields We understand the Water quality trends in the Upper Floridan Aquifer II-9 c) Add redundant wells d) Provide hydraulic flow control of wells (flow, drawdown, conductivity) e) Create raw water quality blending between wells f) Establish pro-active wellfield management system using on-line data to establish well prioritization and production Based on our work with Collier County, we know that several of these best wellfield practices have been implemented. Therefore, this task may be limited to sharing CH2M team’s experiences and successes with these measures. 2. Modify treatment operations to handle variable water quality: a) Change the recovery of reverse osmosis process b) Replace with low energy, high rejection membrane elements to improve the salt rejection c) Change chemical type and adjust chemical doses 3. Minimize the impacts of variable water quality: a) Create raw or finished water blending between the NF and RO treatment systems b) Establish additional post-treatment water treatment conditioning for pH, hardness, and alkalinity EXHIBIT II-d Operational Impacts of Increasing TDS in the Source Water As part of a previous study, operational impacts to a 3.0 mgd BWRO system were evaluated to address an increase of feed water TDS from 3,000 to 9,500 mg/L:  RO recovery reduces from 80% to 70%  Ability to RO bypass reduces from 10% to 2%, with permeate flow making up difference requiring train array to increase from 54-27 vessels to 60-30 vessels  Feed pressure increases from 188 to 282 (with ERD)  Post-treatment chemicals to adjust alkalinity and hardness are increasing with higher TDS  Electricity and chemical costs for RO increase from $0.32 to $0.72 per 1000 gallons treated water Along the same lines, a quick evaluation was done to verify how operations can be changed to allow continued use of the existing RO pressure vessels, which are rated at 600 psi. Please refer below graphic for the results. The pressure rating on the second stage will be exceeded at around 15,000 mg/L TDS. If the RO recovery is dropped from 60 to 50%, the pressure rating of the first and second stage pressure vessels will not be exceeded until feed water TDS reaches values of around 17,500 mg/L II-10  Develop candidate solutions: 1. Treatment process concepts for extreme events with equipment inefficiencies most of time c) Dedicated salt water reverse osmosis (SWRO) system for high TDS water; d) Modify existing system to SWRO The previous variable TDS studies were based on the concept of having to treat well water with the worst quality. This lead to the design of two additional, dedicated high TDS SWRO skids. The consequence of this addition was an increase in the overall WTP capacity from 20 to 22 mgd requiring upgrades to the electrical equipment, power distribution, chemical dosing systems, degasification and odor control, transfer pumping and process building. These upgrades made this solution not competitive in terms of capital and operating costs and therefore were not implemented. 2. Short-term treatment process modifications for elevated TDS feed with phased additional treatment equipment for future extreme events e) Maintain existing BWRO system with minor modifications and add a new treatment technology, like softening, EDR or VSEP membrane technology, if and when needed f) Maintain the existing BWRO system with minor modifications and integrate with existing NF treatment system • Recycle RO permeate back to NF feed for second pass; this may allow a continued use of existing BWRO membrane elements at reduced system recovery avoiding expensive upgrades • Recycle NF concentrate to BWRO feed for TDS reduction; this concept has been pioneered in Florida and at least one system operates successfully with this • Reconfigure to in-series BWRO trains for second pass 3. Implementation of a flexible system g) Modify to new technology, like recirculation desalination by Desalitech, which is operated with concentrate recirculation in batch-mode allowing treatment of high TDS water at relatively high recovery rates and lower energy. For Collier County, this can be an interesting technology to handle the variable TDS water, which can be integrated with existing RO train equipment through the end of its useful life to cost-effectively achieve higher feed TDS treatment over the short- term. As existing RO system components reach the end of their useful life, new components can be installed designed to limits needed for 20,000 mg/L TDS operation.  Provide description and process schematic for each option  List advantages/disadvantages for each option  Utilize our CPES™ cost model to quickly develop accurate comparative capital, operating and lifecycle costs for several alternatives for comparison purposes  Develop a Replica model to optimize operational and capital solution combinations Flexible RO Treats Variable TDS at Increased Recovery Rates A new promising technology by Desalitech utilizes conventional BWRO equipment configured in a different manner, enhanced with recirculation pumps, additional instrumentation and controls. In addition to controlling RO flow and recovery, operators can adjust flux and cross-flow to reduce fouling and scaling while increasing system recovery. Benefits of a flexible RO system are the ability to treat variable TDS feed water instantaneously, increased resistance against scaling, improved recoveries and reduced energy use. II-11  Conduct a benefit cost analysis using CH2M’s decision tools using optimized results  Prepare alternatives comparison technical memorandum  Conduct review meeting and provide meeting summary Task 6 - Conceptual Design After a preferred solution is identified, and agreed upon, under the previous task, further details will be provided in a conceptual design. Previous CH2M models developed in the alternatives evaluation will be updated with the conceptual design criteria to provide project-specific information. An early constructability and operability review with Collier County will identify phasing options at this operational WTP site, needs for temporary facilities or utilities and operational constraints during the implementation. Having identified those aspects early will provide further confidence in the accuracy of the cost estimates and timing of construction. Key sub-tasks include the following:  Develop conceptual design criteria  Assess changes to finished water quality and corrosion control strategy and make recommendations regarding transition period  Constructability and operability review  Update Replica process model and construction and operating costs in CPES using the developed conceptual design criteria  Update costs for budgeting purposes, including developing a financial maintenance model  Develop conceptual design report: o Description of system o Process schematic o Mass balance (using our Source™ mass balance tool) o Hydraulics (refined in Replica) o Design criteria tables o Conceptual layout (refined in Preview) o Controls and electrical systems o Implementation schedule and phasing plan o Capacity analysis over projected timing of the project o Reliability analysis of treatment process components o Cost estimate  Conduct review meeting and provide meeting summary Task 7 - Preliminary Design Following the Collier County’s approval of the conceptual design report, further details will be provided in a 30 percent design particulates. The content of these particulates will be driven by the multiple purposes of the preliminary design report, including:  Allow buy-in and final approval from Collier County  Provide basis of design report requirements of the FDEP for the PWS permit application for the plant changes  Create design criteria document for inclusion in procurement documentation for selection of the design- build contractor C lli C P j Obj i Post-Membrane Water Conditioning for Corrosion Control Treatment of variable TDS feed water will result in variable RO permeate water quality. While the NF permeate will remain the dominant portion in the blend water, variations of individual salts constituents will exist in the finished water. Also, operation of NCRWTP may shift from dominant NF to RO due to O&M activities and this will also have an impact on finished water quality. As part of the work, particular constituents (hardness, alkalinity and chloride-to-sulfate mass ratio) will be modelled using our Source model to assess to need and type of post membrane water stabilization and conditioning for corrosion control. II-12 Key sub-tasks include the following:  Develop preliminary design particulates  Constructability and Operability review  Update operating cost, and Class IV opinion of probable construction cost  Develop draft preliminary design report: o Description of system, design criteria o PFD, hydraulic profile o PIDs o Single line diagrams o Block diagrams, control system architecture, communications o Equipment list, and data sheets o Preliminary layout o Preliminary equipment specifications o Updated equipment replacement/addition/implementation schedule o Projected construction schedules o Updated construction and operating cost estimates  Conduct review meeting and provide meeting summary  Finalize preliminary design report Detailed Time Line of Project An initial project implementation schedule was developed based on the tasks and subtasks described above and an anticipated contract term of 12 months included in the request for proposals. The current schedule shows the submission of the final preliminary design report in week 45 after the notice to proceed. There are factors outside of CH2M’s control affecting the schedule which will be finalized in coordination with the County. Task Activities Deliverable From NTP (in weeks) 1.

In anticipation of this need for expansion, the City asked CH2M HILL to conduct a study in 2007 of viable and cost effective expansion treatment options that would improve finished water quality, better protect public health, meet anticipated regulations, and reduce facility operating cost. The 2007 water expansion study identified membrane filtration, ion exchange, low pressure RO, lime softening, in-line coagulation, and UV as potential treatment processes. However treating a variable surface water like the Marco Lakes source water can pose treatment risks. CH2M HILL therefore conducted an 8-month pilot study that evaluated the treatment feasibility of potential treatment trains. The pilot study confirmed the viability of four potential treatment trains and provided estimated full-scale process design criteria. These criteria were used to rank each of the process options, develop construction and operating cost estimates, and compare overall life cycle costs of each process train. Exhibit 1 shows the projected operating, capital, present worth and life cycle costs for each of the evaluated process trains.

Process train option 4 has the following benefits that make it the most desired process option:  Reduced stress on brackish aquifer – The dependence on brackish groundwater will be minimized because the new treatment process doesn’t require the BWRO permeate for blending to meet finished water quality goals.  Operability: The MF and LPRO units can be shut off and started anytime and are completely automated. The units can treat varying flows thus facilitates part time operation. There are minimal continuous treatment chemicals.  Effective treatment for all finished water goals – The MF and LPRO process would remove all target constituents including hardness, sulfate and chloride without the need for blending.  Expandability: The treatment capacity at the NWTP can be increased to meet future demands due to the relative small footprint of MF.

MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 3 Introduction The City of Marco Island owns and operates two water treatment facilities, the North Water Treatment Plant (NWTP) and the South Water Treatment Plant (SWTP). The NWTP is a conventional lime softening plant that treats the Marco Lakes surface water and has a capacity of 6.7 MGD. The lime softening facility primarily removes hardness, organics, turbidity, and potential pathogens from the surface water supply. The SWTP is a Reverse Osmosis (RO) treatment facility that treats brackish well water and has a capacity of 6.0 MGD. The RO process removes salt from the brackish feed water that exceeds drinking water standards for TDS, sodium, chloride, and sulfate. A portion of the treated water from the NWTP is blended with the RO permeate to add hardness to the SWTP finished water and stabilize it before distribution. The NWTP is operated continuously above 6.0 mgd and the SWTP is used to meet the remaining demand. The City plans on expanding potable water production capacity at the NWTP to meet increasing water demands and reduce the stress on the brackish aquifer at the SWTP. The new treatment process train must treat Marco Lakes water at the NWTP, meet current and proposed future regulations, blend with RO permeate at the SWTP, and produce water that is similar to or better than existing water quality. The City has contracted CH2M HILL to explore potential process options for treating additional Marco Lakes water. This technical memorandum (TM) describes the Marco Lakes source water quality, the desired finished water quality, the treatment processes that can meet these goals, and potential process trains for the expansion. Source Water and Finished Water Quality The Marco Lakes raw water source is located approximately 10 miles north of the island and is fed by the Henderson Creek and influenced by surficial groundwater. The City also uses Aquifer Storage and Recovery (ASR) wells that are recharged during the wet season and then used for additional capacity during the dry. The ASR recovered water is blended with the surface water or used alone to feed the NWTP in the dry season. Both the Marco Lakes surface water and recovered ASR well water are influenced by groundwater with elevated levels of chloride and sulfate. Exhibit 3 presents the range of feed water quality entering the NWTP. The treated water must be similar to or improve upon existing finished water quality, as well as meet current and proposed future regulatory requirements including Florida Department of Environmental Protection (FDEP) primary and secondary drinking water standards, the Stage 2 Disinfection / Disinfection Byproducts Rule (S2DBPR) and the Long- Term 2 Enhanced Surface Water Treatment Rule (LT2SWTR). Exhibit 3 presents the City’s anticipated finished water quality goals. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 4 EXHIBIT 3 Marco Lakes Raw Surface Water Quality and Desired Finished Water Quality Marco Island North Water Treatment Plant Expansion Options Parameter Marco Lakes Surface Water Quality Range (Average) Finished Water Quality Goal pH 7.2 – 8.2 (7.8) 8.8 Temperature (Celsius) 20 – 32 (26) - Chloride (mg/L) 66 – 154 (120) < 100 Sulfate (mg/L) 40 – 150 (100) < 80 TDS (mg/L) 190 – 600 (410) < 400 Total alkalinity (mg/L as CaCO3) 120 – 340 (235) > 35 Total hardness (mg/L as CaCO3) 170 – 380 (330) 100-120 Turbidity (NTU) 0.5 – 21 (1.5) < 0.3 TTHM (µg/L) - 80 HAA5 (µg/L) - 40 Total organic carbon (mg/L) 9.3 – 17 (14) 10* Color (PCU) 20 – 70 (35) < 5 * Based on EPA D/DBPR requirement of 30% TOC removal; actual removal may be greater depending on selected treatment process. The raw Marco Lakes water is high in color, hardness, and total organic carbon (TOC) including disinfection byproduct (DBP) precursors. The surface water may also include pathogens that require removal or inactivation. The high concentrations of sulfate and chloride may be contributing to copper corrosion problems on the north end of the island. The selected process must effectively address these target constituents to meet the desired water quality goals. The finished water quality must be stable (non-corrosive) with a pH near 8.8, total alkalinity above 35 mg/L as CaCO3, and total hardness between 100 to 120 mg/L as CaCO3. The treatment process should minimize increases in sulfate and chloride, or even reduce them in order to control copper corrosion. The new treatment process should meet all of these goals before blending with the existing BWRO permeate that may be limited in the future. The finished water must meet the S2DBPR by achieving 30 percent TOC removal and maintaining a TTHM concentration below 80 g/L and a HAA5 concentration below 40 g/L at all points within the distribution system. The water must also meet the S2SWTR by achieving 3-log Giardia, 2-log cryptosporidium and 4-log virus removal using a multiple barrier disinfection approach and maintaining filtered water turbidity below 0.3 NTU. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 5 Treatment Processes to Address Target Constituents Potential treatment processes that can remove organics, hardness, pathogens, turbidity, chloride and sulfate were identified for consideration. These processes include:  Membrane filtration  In-line coagulation  Ion exchange  UV disinfection  Lime softening  Low pressure reverse osmosis A general process description, target constituents, and process features for each of these treatment processes are included in the sections below. Membrane Filtration The proposed membrane filtration (MF) system is a beneficial process component when treating surface water and is therefore common to all process options. Membrane filtration receives the most credit for pathogen removal by the LT2SWTR and produces consistently low turbidity finished water independent of feed water turbidity. The Pall pilot study demonstrated that their membrane filtration system can successfully treat raw water, lime softened water, and in-line coagulated raw water. The differing feed water types do not impact membrane system configuration, but do impact the design flux rate, EFM interval, EFM chemicals, and CIP interval. Lake water treatment by lime softening and coagulation increase the need for citric acid EFMs. The clarified lime softened water improves the sustainable flux rate while in-line coagulation without clarification increases the solids loading on the membranes and therefore reduces sustainable flux rate. The MF system trains are divided into banks containing several pressure vessels or cartridges. The individual train flow remains relatively constant while individual banks are backwashed. The MF systems typically operate in a “dead-end” configuration and backwash at high trans-membrane pressure (TMP) or on a set time interval depending on the feed solids loading (typically 10 to 60 minutes). Occasionally, the system automatically performs an enhanced flux maintenance (EFM) that includes recirculating a citric acid or sodium hypochlorite solution around or through the membrane fibers for approximately 30 minutes. On a monthly basis or greater, depending on the level of fouling, individual trains of the membrane system are scheduled for a clean- in-place (CIP) cycle where a citric acid or sodium hypochlorite and/or sodium hydroxide solution is recirculated through the membranes for an extended period of time to restore productivity that could not be restored through backwash or EFM. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 6 Target Constituents  Pathogens (Giardia, Crypto and some virus)  Turbidity Design Criteria  Flux – 60 to 80 gfd  Recovery – 90 to 95%  Backwash interval – 30 minutes  EMF interval – 3 days (alternating citric / hypochlorite)  CIP interval – > 30 days (citric / hypochlorite + caustic) Process Features  Superior pathogen and turbidity removal – membrane filters are an absolute barrier to pathogens larger than the design pore size including Giardia and Cryptosporidium. Membrane filtration can be credited with up to 5-log Giardia and Crypto removal, however a practical upper limit is 4-log for full-scale systems as demonstrated by direct integrity testing. Finished water turbidity is always less than 0.1 NTU independent of upstream water quality.  Excellent pretreatment for downstream RO processes – Membrane filtrate virtually eliminates particulate fouling in downstream RO systems.  Small footprint – Membrane filters operate at high loading rate or flux and the hollow fiber construction allows a high surface area in a small footprint.  Operability: Individual units can be started or stopped anytime and flow can be adjusted up to the maximum design flux. The system is completely automated during normal operation, backwash and EFM.  Expandability – MF systems are modular and can be easily expanded with additional equipment installation and minimal infrastructure.  Backwash and cleaning chemicals – The membrane filtration system typically uses citric acid, sodium hydroxide, and sodium hypochlorite for daily maintenance cleans and monthly clean-in-place (CIP) events.  Low operating cost – MF systems operate at a TMP between 4 and 30 psi with minimal chemical usage.  Backwash disposal – MF require disposal of backwash waste that is typically 3 to 10 percent of the feed flow. In-Line Coagulation In-line coagulation would be used to inject coagulant (ferric chloride or aluminum sulfate) into the raw water pipeline to help coagulate dissolved organics in the raw water to promote their removal by the MF system. An in-line rapid mixer would provide effective mixing of the coagulant and help bind the dissolved organics to suspended pin floc that would be subsequently removed by downstream filtration. An in-line coagulation and mechanical mixer design drawing is shown in Exhibit 4. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 7 EXHIBIT 4 In-line mechanical mixer design drawing Marco Island North Water Treatment Plant Expansion Options Target Constituents  Color  TOC  DBP precursors Design Criteria  Coagulant – Aluminum sulfate (~80 mg/L) or ferric chloride (~25 mg/L)  Mixer type – in-line powered mixer with variable speed motor Process Features  Excellent pretreatment for downstream MF – The coagulation of dissolved organics reduces fouling in downstream MF treatment.  Low capital cost – The in-line coagulation system is simple including only a chemical tank, metering pump, injectors, and a mixer  Small footprint – The in-line coagulation system has minimal equipment and would be installed into the feed water piping.  Additional sludge management: The addition of solids could reduce the efficiency of the filtration process. Recycling the sludge to the lime plant would add operational costs.  Potentially high chemical usage – The coagulant dose required to achieve the desired TOC and color removal can be up to 100 mg/L. The raw water pH may also have to be reduced for optimum coagulation thus requiring a strong acid like sulfuric acid or hydrochloric acid.  Increased salts – Coagulant and acid feed increases chloride and/or sulfate in the treated water. Ion Exchange The proposed ion exchange (IX) system would use an anion exchange resin in pressure vessels that selectively exchanges organics including TOC, color, and DBP precursors in the feed water with chloride. A two-step regeneration process would then backwash and regenerate the resin using a high concentration sodium chloride solution. The adsorption and regeneration steps are conceptually shown in Exhibit 5.

The unit facilitates part-time operation because it can treat varying flows.  Excellent color and organics removal - Almost complete color removal and up to 70% organics removal. The improved organics removal leads to reduced DBP formation.  Increased salts in treated water – Exchange between chloride and organics increases the chloride concentration in finished water.  Minimal chemicals – Only salt is needed to regenerate the resin.  Brine disposal – Regeneration of the resin creates a brine waste with a high sodium chloride concentration that requires proper disposal  No Repumping – The ion exchange is housed in pressure vessels that allow installation in-line without breaking head. Ultraviolet Disinfection UV disinfection is a physical process that uses photochemical energy to prevent cellular proteins and nucleic acids (i.e., DNA and RNA) from further replication. A cell that cannot replicate also cannot infect. The germicidal UV light wavelengths range from 200 to 300 nm with the optimum germicidal effect occurring at 253.7 nm. UV is a reliable component of a multi disinfectant treatment strategy often used in conjunction with chlorine to provide a dual barrier. The concept is further illustrated in Exhibit 6. EXHIBIT 6 Multi Barrier UV Protection Marco Island North Water Treatment Plant Expansion Options Courtesy: Trojan UV Exhibit 7 further illustrates the resistance of waterborne pathogens to UV. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 10 EXHIBIT 7 Pathogen Resistance to UV City of Marco Island UV Disinfection Evaluation Two of the most common UV systems available in the market are the Low Pressure systems and the Medium Pressure systems. A brief description of each type is given below. Low Pressure UV Systems The low pressure (LP) UV systems include low intensity, high intensity and amalgam lamps. The low pressure lamps emit monochromatic UV light and the majority of the emissions are produced at the germicidal wavelength of 254 nm. The LP UV systems are relatively efficient because approximately 40% of the input energy is converted to germicidal UV and the lamps operate at temperatures between 40-95°C. However, the LP UV lamps are lower intensity than medium pressure lamps and therefore require a significantly larger footprint. Some of the advantages of LP lamps include greater lamp life than medium pressure lamps, low energy consumption, and lower fouling than medium pressure lamps because of lower operating lamp temperature and lower UV density. Medium Pressure UV systems Medium-pressure (MP) UV lamps produce significantly more UV light than low pressure lamps. The total UV Type C output (i.e., wavelengths from 200 to 280 nm, the most germicidal range) from a MP lamp is roughly 30 to 150 times higher than the output from a LP lamp. However, the MP lamps produce output with a broad spectral energy distribution, so the lamps are much less efficient at converting energy to germicidal energy. The polychromatic output covers wavelengths that have different levels of germicidal effectiveness. Combining the effects of the polychromatic light spectrum and the shorter lamp lengths, the UV output from an MP lamp is typically about 10 to 20 times higher than output from an LP lamp. The MP lamps need frequent cleaning as they operate at high temperatures, have a shorter lamp life, and demand higher power compared to LP lamps. Exhibit 8 summarizes the key features of low pressure and medium pressure UV systems.

EPA regulations require a plant to achieve 4-log virus inactivation after the water is exposed to air during a treatment process. UV disinfection could provide the additional 2-log virus inactivation post filtration without the need for extensive contact time. The 0.5 MG storage tanks can be reallocated to the water reclamation facility. 2. The plant currently falls under Bin 1 under the Long-Term 2 Enhanced Surface Water Treatment Rule (LT2) and hence does not require inactivation of cryptosporidium. However, changing watersheds for the NWTP source water could quickly change this bin classification without warning and require more disinfection. 3. UV’s cost-effectiveness and ability at low doses to inactivate the pathogenic protozoa (resistant to chlorine disinfection methods) will provide added benefits to meet future disinfection requirements. 4. A UV system would provide virus, Giardia and cryptosporidium inactivation with the virus inactivation as the limiting criteria for determining UV dose. 5. The City would improve public health protection with multiple disinfection barriers. 6. High organics in the raw surface water is a concern for the City because of disinfection by products formation. Use of UV reduces use of free chlorine for disinfection, thus reducing DBP formation. The free chlorine injection point could be moved closer to the ammonia injection point because of lower CT requirements, leading to lower DBP formation. The proposed UV system would be an in-line reactor as shown in Exhibit 9 that would be installed on the membrane filtered water line before blending with finished water from the existing SWTP or NWTP. The UV system would be used for primary disinfection including meeting the multiple barrier inactivation requirements of Giardia and Cryptosporidium, as well as the required residual virus inactivation. EXHIBIT 9 UV Disinfection unit Marco Island North Water Treatment Plant Expansion Options MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 13 Target Constituents  Pathogens Design Criteria  UV dose – 50 mJ/cm2  UV Transmission - > 90%  Target Giardia inactivation – 0.5-log  Target Cryptosporidium inactivation – 2.0-log  Target virus inactivation – 3.0-log Process Features  Operability - UV is simple to install and requires minimal space, supervision and maintenance.  DBP and free chlorine reduction - Eliminates the use of free chlorine as a primary disinfectant and reduces DBP formation.  Low construction cost – The UV process has minimal equipment and may be installed in filtered water piping thus reducing construction cost.  High operating cost: Operating cost is high relative to using free chlorine as primary disinfectant.  No Disinfection residual – There is no disinfection residual in the water, thus requiring a secondary disinfectant like the chloramines currently used by Marco Island.  Restricted water quality – Not suitable for water with high color, turbidity and dissolved organics. Low Pressure Reverse Osmosis Low pressure reverse osmosis (LPRO) is the same process as the brackish water RO (BWRO) system used at the SWTP. The LPRO system operates at a lower pressure (< 150 psi versus > 300 psi) with some reduction in salt rejection (> 95% versus > 99%). The LPRO membranes will effectively remove the target constituents from the pretreated Marco Lakes water. The existing BWRO trains at the SWTP can be used for a LPRO application by exchanging the existing BWRO membrane elements for LPRO membrane elements and de-staging the membrane feed pumps. The existing BWRO trains membrane can be used with limited modification with the existing membrane elements and feed pumps as well at a higher operating cost. Operating with the existing feed pumps and BWRO membrane elements would allow the use of the trains for either surface water or brackish well water treatment. Target Constituents  Salts (TDS, chloride, sulfate)  Hardness  Color  TOC  DBP precursors MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 14 Design Criteria  Flux – 12-15 gfd  Recovery – 85 to 90%  Feed pressure – 100 to 150 psi  Salt rejection > 95%  Treated hardness – < 10 mg/L as CaCO3  TOC reduction – > 95%  Treated color – < 2 PCU  Treated chloride and sulfate – 5 to 10 mg/L Process Features  Removes most feed water constituents – The LPRO system will highly reject TOC, color, DBP precursors, TDS, chloride, sulfate, and hardness.  Operability – LPRO is automated and is easy to start and stop with changing demands. Maintenance is minimal.  Small footprint – The LPRO system is contained in compact trains that can fit into a small footprint.  Post-treatment stabilization – RO permeate is aggressive and will corrode distribution system piping unless post-treated or blended with feed water bypass flow.  Requires pretreatment – Upstream membrane filtration and potentially minimal coagulation and biocide addition would be needed to reduce the fouling potential of the raw surface water. RO membranes are not suitable for treating water with high turbidity or organic/biological fouling potential.  Concentrate disposal – A portion of the feed water (10 to 20 percent) is lost to the concentrate stream and requires proper disposal. The concentrate can be injected into a concentrate injection well, or possibly sent to the WWTP for eventual use as irrigation water. Enhanced Lime Softening Conventional softening uses lime to increase pH of the feed water to reduce the solubility of calcium carbonate (above pH 9.0) and magnesium carbonate (above pH 11.0) thus precipitating calcium and magnesium hardness that subsequently settles out in a reactor/clarifier. The precipitate created by this softening process also removes feed water turbidity. Enhanced lime softening uses the precipitation of magnesium Mg(OH)2 at high pH, or coagulant added with the lime in the reaction zone to remove color, TOC and DBP precursors that are otherwise not removed in the lime softening process. A lime softening reactor/clarifier has been illustrated in Exhibit 10.

Process Train Options Each of the unit processes above were used to develop the process train options listed below for the treatment of 4 mgd of Marco Lakes raw water at the NWTP site. Each of these process train options is designed to meet current and proposed future regulatory requirements as well as the Marco Island finished water quality goals. 1. In-line coagulation/membrane filtration/UV/blending with BWRO permeate 2. Membrane filtration/Ion Exchange/UV/blending with BWRO permeate 3. In-line coagulation/enhanced lime softening/membrane filtration/UV 4. Membrane filtration/converted LPRO train/UV/blending with BWRO permeate For each of these options, the flow through the existing NWTP conventional lime softening train would be decreased during normal operation to 5 mgd to improve operability and ensure the existing system can handle raw water quality excursions. This reduction in flow would coincide with the decommissioning of the existing Zenon membrane system. The sections below describe each of the process train options in more detail including target treatment constituents, process flow diagrams, site layouts, process advantages, and potential process limitations.

Each of the processes were selected for their ability to remove the target constituents listed in Exhibit 11.

The MF process, located on the NWTP site, would then remove the floc, turbidity and pathogens from the coagulated water. A new filtrate pump station would transfer the filtered water through an in-line UV system and ultimately to the SWTP for blending with RO permeate. Exhibit 12 shows the proposed process flow diagram for this process option. Exhibit 13 shows a conceptual layout at the NWTP site.

Process Limitations  High coagulant and sulfuric acid dosing – Pilot study data shows that high doses of ferric chloride or aluminum sulfate are required to meet color and TOC goals. The high chemical dosing has the following impacts:  High operating cost ($50k/year in chemical cost alone)  Reduced downstream MF flux due to the additional solids loading. A small amount of coagulant (5-10 mg/L) improves membrane system performance, however the target doses up to 80 mg/L reduce MF flux from 80 gfd to 60 gfd. This increase in flux increases MF system cost.  Increased finished water chloride and sulfate from the sulfuric acid (H2SO4) and alum (AL2(SO4)3) or ferric chloride (FeCl3). The increase in chloride and/or sulfate may be as high as 50 to 150 mg/L.  Additional sludge production due to the increased solids created by coagulation  Operator safety when handling sulfuric acid and coagulants MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 19  Incomplete TOC and color removal – Pilot test results show that in-line coagulation will only reduce TOC by 10 percent and reduce color to 15 - 20 PCU. Higher coagulant doses needed to meet TOC and color removal goals increase the solids loading on the MF system to above sustainable levels.  Requires blending with RO permeate – The proposed treatment processes do not remove hardness and nor the required TOC and color. Blending with RO permeate is needed to reduce these target constituents as well as chloride and sulfate that may impact copper corrosion. The production capacity of the new process train would be limited to operating only when the RO system at the SWTP is operational. A minimum blend ratio of 1:2 (MF filtrate: BWRO permeate) would be needed to reduce finished water color to 5 PCU and total hardness to approximately 100 mg/L as CaCO3. Process Train Option 2 – Membrane filtration/Ion Exchange/UV/blending with BWRO permeate Process Option 2 includes membrane filtration of the raw Marco Lakes water followed by ion exchange, UV, and blending with BWRO permeate at the SWTP. Each of the processes were selected for their ability to remove the target constituents listed in Exhibit 14.

The IX system would reduce TOC and eliminate color from the membrane filtrate. A new filtrate pump station would transfer the filtered water through an in-line UV system and ultimately to the SWTP for blending with RO permeate. The downstream UV treatment would provide the required additional ½ log Giardia and 3-log virus inactivation. The treated water would have high hardness, alkalinity, sulfate and chloride that would be blended with RO permeate to help meet finished water quality goals.

While the increase in chloride would only be 10 to 20 mg/L, these modest increases may further increase issues with copper corrosion.  Requires blending with RO permeate – The proposed treatment processes do not remove hardness. Blending with RO permeate is needed to reduce total hardenss as well as chloride and sulfate that may impact copper corrosion. The production capacity of the new process train would be limited to operating only when the RO system at the SWTP is operational. A minimum blend ratio of 1:2 (MF filtrate: BWRO permeate) would be needed to reduce finished water total hardness to approximately 100 mg/L as CaCO3.  Brine disposal – The IX system produces a bring waste that would require some capacity in the existing injection wells. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 22 Process Train Option 3 – In-line coagulation/lime softening/membrane filtration/UV This treatment process option includes in-line coagulation followed by a new enhanced lime softening reactor/clarifier to remove hardness, turbidity, color, and organics followed by MF for pathogen and residual suspended solids removal. Each of the processes were selected for their ability to remove the target constituents listed in Exhibit 17.

Additional improvements would include a new in-line coagulation system that would feed both the existing and new lime softening reactor for improved organics removal and a UV system that would disinfect all of the water treated by the NWTP ensuring that both process trains meet the required 3-log Giardia and 4-log virus inactivation without the need for a chlorine contact basin. Exhibit 18 shows the proposed process flow diagram for this process option. Exhibit 19 shows a conceptual layout at the NWTP site.

MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 24  Harness and organics removal – The enhanced lime softening process can effectively reduce hardness, organics and color to meet drinking water standard without the need for blending with RO permeate.  Low fouling – The lime softening treatment process is not impacted by the fouling potential of organic material in the feed water.  Finished water distribution flexibility – The treated water would be distributed at the NWTP or at the SWTP because the treated water doesn’t require blending to meet finished water quality goals. Process Limitations  Operability – Part-time operation is difficult due to the long start-up time required to stabilize the lime softening process. The lime softening process requires continuous monitoring and adjustment with changing feed water quality  Large footprint – The lime softening process has a large footprint and may not fit well on the NWTP site without variances on setbacks and layouts that result in limited access to treatment components.  High operating cost – If operated for optimum TOC and color removal, the enhanced lime softening process will use more lime and generate significantly more solids that will require disposal. Both the added lime and sludge will increase operating cost.  Membrane scaling – The downstream MF units will be susceptible to CaCO3 scaling, especially during softener upsets. Operation of the membrane system downstream of lime softening may require more frequent acid cleaning or a lower operating flux rate.  Finished water chloride and sulfate – The lime softening process doesn’t remove chloride or sulfate and the use of coagulant will increase concentration somewhat. Process Train Option 4 – Membrane filtration/UV/converted LPRO train/blending with BWRO permeate This process option uses MF for removing turbidity and pathogens, as well as pretreatment for downstream LPRO. A new pump station would transfer the filtrate to the SWTP for further treatment by LPRO and UV disinfection. Each of the unit processes have been selected to remove the target constituents shown in Exhibit 20 EXHIBIT 20 Process Train Option 4 Process Constituent Removal Marco Island North Water Treatment Plant Expansion Options Treatment Process Target Constituents Membrane filtration Pathogens, turbidity LPRO Hardness, color, TOC, DBP precursors, TDS, chloride, sulfate UV Multiple barrier Giardia inactivation, virus inactivation MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 25 One or two of the existing BWRO trains at the RO WTP would be converted to LPRO by replacing the existing brackish water membranes with low energy membrane elements. These low energy elements would remove hardness, TOC, color, chloride, and sulfate from the feed water at a much lower pressure (< 150 psi) compared to BWRO. The membrane permeate would be blended with a feed water bypass stream, sent through UV for the required additional ½ log Giardia and 3-log virus inactivation, and then blended with BWRO permeate in the ground storage tanks. Exhibit 21 shows a process flow diagram for this process train option Exhibit 22 shows a conceptual layout of the membrane filtration system at the NWTP. The LPRO and UV systems would be located inside the existing SWTP membrane building. The existing BWRO trains membrane may also be used with limited modification while using the existing membrane elements and feed pumps. This option would increase operating cost, however it would decrease initial cost and would allow the use of the trains for either surface water or brackish well water treatment.

The units can treat varying flows thus facilitates part time operation. There are minimal continuous treatment chemicals.  Effective treatment for all finished water goals – The MF and LPRO process would remove all target constituents including sulfate and chloride without the need for blending.  Expandability: The treatment capacity at the NWTP can be increased to meet future demands due to the relative small footprint of MF. Process Limitations  Additional pilot testing – Additional pilot testing should be performed with RO to verify fouling rate and determine operating protocol including additional pretreatment.  Potential need for in-line coagulation – Additional pilot testing may show that a low dose of coagulant would be needed to reduce organic fouling of the LPRO membranes.  Expansion at SWTP site – Modifications would be required at the SWTP that may effectively increase the capacity of the SWTP above 6 mgd. The higher capacity may require additional staffing. MARCO ISLAND WATER TREATMENT EXPANSION OPTIONS MARCO NWTP EXPANSION OPTIONS TM - 1-11-10 27  Concentrate disposal – LPRO concentrate disposal could be an issue. The deep well injection at the NWTP would be used to dispose the concentrate.

The degrading quality is creating operating challenges and increasing treatment cost. Changing water quality has also increased the estimated construction cost of the proposed ultraviolet (UV) disinfection system that was identified as a cost effective treatment for meeting the upcoming Long-Term 2 Enhanced Surface Water Treatment Rule (LT2 ESWTR). The NWTP maintenance cost is increasing because of aging water treatment infrastructure. Recent inspections have identified major rehabilitation needs of the existing granular media filters (GMF), Zenon membrane filtration (MF) system, and lime reactor. These rehabilitation projects will require significant downtime of the NWTP and result in $1.5M in additional maintenance cost. The maintenance staff anticipates a higher frequency of these types of rehabilitation projects as the infrastructure continues to age. CH2M HILL conducted an evaluation of potential treatment rehabilitation/upgrade options to determine solutions that will improve treatment facility reliability and operability given the changes in source water quality, as well reduce capital and operating cost over both now and in the future. Options included combinations of rehabilitation versus replacement of the existing media filters with a new MF system, rehabilitation versus replacement of the existing Zenon system, and alternative UV disinfection options. CH2M HILL identified three primary options including: 1. Rehabilitating the existing filters, lime reactor, and Zenon system, replacing the existing transfer pumps, and installing UV for full virus, Giardia, and Crypto inactivation required by the upcoming regulations. 2. Rehabilitating the lime reactor and filters, replacing the Zenon system with a new MF system, and installing UV for only Giardia and Crypto inactivation, while modifying the hypochlorite feed system to achieve the required virus inactivation. 3. Rehabilitating the lime reactor, while replacing the existing filters and Zenon system with a new MF system that also can potentially meet the upcoming Giardia and Crypto removal requirements. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 2 Recommendation CH2M HILL recommends that the City replace the existing filters and Zenon system with a new membrane filtration system as outlined in Option 3. This new membrane filtration system will provide several benefits including:  Provide the most cost-effective long-term capital and operating cost solution for the City.  Reduce the money wasted on short-term improvements that have limited or no-long term benefit.  Improve the finished water quality, operability and reliability of the NWTP process.  Use the best available technology to manage degrading source water quality while ensuring compliance with upcoming regulations. The exhibit below shows a summary of the capital and operating costs for the three primary options. Additional cost assumption detail is provided in the attached spreadsheets. EXHIBIT 1 Marco Expansion Options Cost Summary Item Option 1 Option 2 Option 3 Option 3 (no UV) Capital Cost with Contingency $4,953,900 $4,118,300 $4,727,500 $4,132,800 Approximate Future Exp Cost $3,400,000 $1,000,000 $1,000,000 $1,000,000 Operating Cost ($/kgal) $0.868 $0.653 $0.641 $0.635 Operating Cost ($/year at 6 mgd) $1,902,000 $1,430,000 $1,403,000 $1,391,000 Background UV System Cost Impact from Source Water Quality Change CH2M HILL conducted an initial investigation of ultraviolet light disinfection (UV) for virus inactivation of lime softened and filtered Marco Lakes water in August 2009 using the results of the membrane filtration pilot testing conducted in 2008. Pilot testing showed that a filtered water UV transmittance (UVT) between 92 and 96 percent during July/August, historically the time of year with the highest source water TOC and therefore anticipated to have the lowest UVT. Based on this high UVT range, which would result in high UV efficiency and low UV power consumption, CH2M HILL recommended that the City of Marco implement UV disinfection in order to comply with both the requirements of the EPA LT2ESWTR and FDEP “bird rule”, while eliminating the need for the existing 0.5-MG storage tanks. Recent changes in water quality in Marco Lakes water quality, stemming from changes in the natural organic matter content of Henderson Creek water, have reduced North Water MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 3 Treatment Plant (NWTP) filtered water UVT to approximately 70 percent, despite a decrease in color levels from 35 PCU to 23 PCU. In response to this water quality change, CH2M HILL conducted jar testing during March 2010 to identify changes to alum and/or lime dosing that could improve the filtered water UVT. The jar testing results indicate that UVT has some dependence on lime dose (higher dose improves UVT) and on pH during alum addition (lower pH improves UVT), however alum dose has minimal impact. In all cases, the best UVT that could be achieved was 76 percent. This compares to the 92-95 percent UVT measured in August 2009. The significantly lower filtered water UVT has a major impact on UV system design: UV system footprint, equipment and O&M cost are all estimated to double. UV system construction cost is expected to increase by at least $600,000. Filter Rehabilitation The City is in the initial stages of rehabilitating the existing NWTP lime reactor and media filters. The Florida Department of Environmental Protection (FDEP) has mandated that the City make improvements to the structural components of these systems as well as replace the filter media. These improvements are anticipated to cost $1.2M and are expected to take up to 2 months to complete. The existing Zenon membrane filtration system, installed in 1998 and which representing 20 percent of the total filtration capacity at the NWTP, is aging and is showing signs of imminent failure. To restore structural and performance integrity, a minimum of 50 percent of the membrane cassettes must be replaced, and the steel tank requires significant refurbishment or replacement. Estimated cost for repair and/or replacement is a minimum of $560,000 and must be completed in the near future to maintain the current NWTP capacity of 6.7 mgd. The City has explored options for temporary treatment during the anticipated 2-month shutdown of the lime reactor and filters. A treatment system that can meet current SWTR regulations without the use of the existing lime softening process is needed. Installing a membrane filtration system with integrity testing capability that can provide a minimum 3- log Giardia removal is a cost-effective option that can be implemented for a short period of time. FDEP acceptance of this kind of direct filtration system is expected when used with a free chlorine residual in the distribution system to achieve secondary Giardia disinfection (part of normal annual distribution system maintenance) and blending with RO permeate at the SWTP to reduce color and hardness. The cost of a temporary membrane filtration system is estimated at $275,000 including equipment rental, installation, startup and decommissioning. Future Membrane Filtration Expansion The City is planning to expand the NWTP by 4 mgd in 2013 to meet increasing finished water demand on the island. An expansion evaluation conducted by CH2M HILL in 2007 identified direct filtration of the NWTP Marco Lakes source water using a microfiltration (MF) or ultrafiltration (UF) as a cost effective expansion option if the filtered water was transferred to the SWTP and then further treated with reverse osmosis (RO) or blended with RO permeate from the existing treatment system. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 4 The City and CH2M HILL conducted a membrane filtration pilot study between January and August of 2008 to identify the feasibility and cost of treating the Marco Island NWTP source water with membrane filtration. A microfiltration (MF) pilot unit supplied by Pall Corporation was used for the testing and displayed excellent performance when treating raw water, in-line coagulated raw water, and lime softened water from the existing full- scale reactor. Based on the results of the pilot study, the membrane filtration equipment cost was estimated at $1.4M. After installing a building and other related process components, the anticipated cost for the expansion was estimated at $7M. Alternative Approaches CH2M HILL began to evaluate alternatives for the temporary filtration system needed during the rehabilitation, as well as the cost feasibility of installing a replacement to the existing Zenon membrane filtration system. During the evaluation, Pall Corporation introduced a new 2-mgd pre-packaged MF system with an approximate cost of $600,000. This new package system, the Aria AP8, represents a significant cost savings over previously quoted custom systems, and allows for significantly lower cost design and installation than a custom system. The City therefore has decided to revisit the current rehabilitation, UV and membrane filtration expansion plan given the following factors:  Introduction of the lower cost 2-mgd MF pre-packaged skid  The unexpected $1.5M cost for rehabilitation of the media filters and lime softening reactor.  The recent degradation of the Zenon system and anticipated $600k rehabilitation cost  The unexpected $600k increase in cost of the UV system.  The upcoming planned expansion using membrane filtration Given these factors, two alternative options have been developed that seek to minimize the investment in short-term fixes and old equipment and take advantage of recent cost reduction in membrane filtration to improve the finished water quality, operability and reliability of the NWTP. The sections below summarize three different approaches to the current and future expansion of the filtration and UV systems. Option 1 – Rehabilitate Lime Reactor, Zenon and Media Filters and Install UV for 4-log Virus Inactivation Description This option includes rehabilitating the existing filters, lime reactor and Zenon system. UV will be installed to achieve the virus, Crypto, and Giardia inactivation required by the upcoming LT2ESWTR and FDEP bird rule after eliminating the 0.5MG tanks currently used for virus and Giardia inactivation CT. Rehabilitating the existing media filters and Zenon system would be adequate given that the new UV system would be installed to meet the LT2ESWTR. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 5 Improvements / Action Items 1. Rehabilitate existing lime softener and media filters August-September 2010. 2. Meet with FDEP to discuss rehabilitation and ensure approval and permitting of short- term direct filtration treatment using rental units. 3. Lease LT2 compliant membrane filtration units to allow 2 mgd of production during the rehabilitation period.  Operate these units in direct filtration mode with upstream alum feed to reduce color.  Obtain FDEP approval and permit to distribute MF-filtered water in conjunction with maintaining a free chlorine residual during distribution and blending with RO permeate at the SWTP.  Obtain FDEP approval and permit to distribute MF-filtered water to achieve 3-log Giardia removal credit without the need for free chlorine residual or permeate blending.  Pending FDEP approval, distribute un-softened MF-filtered water from the NWTP during the rehabilitation. 4. Rehabilitate existing Zenon system to maintain current 6.7 mgd NWTP capacity beyond the rental period of the MF units. 5. Install UV system for 2-log Virus and 3+ log Giardia and Crypto inactivation to meet bird rule and LT2 without CT in storage tanks. 6. Install new transfer pumps to allow direct pumping to SWTP and 4MG tank thus reducing operating cost and allow reallocation of existing 0.5MG tanks to RWPF. 7. Install future MF skids and building when expansion is required. Potential Issues and Disadvantages  Short-term permitting during rehabilitation  Increased construction and operating cost of UV system to meet 2-log virus inactivation at lower UVT (minimum 70%).  Money is spent on systems that may only last another 3-5 years. This options would require ~$3.4M expansion cost in the future for membrane filtration, building, UV, piping, & SWTP modifications.  Risk of UV non-compliance due to the change in the nature of the Marco Lakes Source water.  While the 50% measured UV transmittance is similar to the values measured during the pilot, the existing lime softener is having difficulty achieving UVT values that are consistently above 70%.  Jar testing shows that achieving UVT above 75% would be difficult with the current treatment system and modifications to the alum addition (including mixing and pH adjustment) may be needed. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 6  Validation of UV equipment at UVT below 70% may be required to ensure continued compliance (units are not currently validated below 70%) Advantages  Makes full use of existing treatment equipment.  Requires the least amount of engineering design  Defers most of the NWTP expansion cost. Option 2 – Rehabilitate Media Filters, Replace Zenon, Modify Chlorination Addition, and Install Smaller UV Description This option includes rehabilitating the existing media filters and lime reactor, but replaces the existing Zenon system with a new LT2-compliant membrane filtration system. The option also includes relocating the existing chlorination point to allow virus inactivation with free chlorine post-filters and adding chlorine to the filter backwash to control algae growth. Improvements / Action Items 1. Rehabilitate existing lime softener and media filters August-September 2010. 2. Meet with FDEP to discuss rehabilitation and ensure approval of short-term direct filtration treatment using rental units. 3. Purchase LT2 compliant membrane filtration unit to allow 2 mgd of production during the rehabilitation period.  Install in a temporary structure until a permanent structure is constructed.  Operate this unit in direct filtration mode with upstream alum feed to reduce color.  Obtain FDEP approval and permit to distribute MF-filtered water in conjunction with maintaining a free chlorine residual during distribution and blending with RO permeate at the SWTP.  Obtain FDEP approval and permit to distribute MF-filtered water to achieve 3-log Giardia removal credit without the need for free chlorine residual or permeate blending.  Pending FDEP approval, distribute un-softened MF-filtered water from the NWTP during the rehabilitation. 4. Construct a new membrane filtration building and re-locate rented membrane filtration package system to a permanent location inside the building. 5. Install UV that is sized for 2.5-log Giardia and Crypto inactivation to meet Long-Term 2 ESWTR requirements. 6. Relocate current hypochlorite injection point to the clearwell, or in the pipeline downstream of the UV system after exposure of process water to open atmosphere to meet the requirements of the FDEP bird rule. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 7 7. Relocate the ammonia feed point to a minimum of 30 seconds HRT downstream of the hypochlorite injection point after achieving the required 2-log virus inactivation. 8. Add hypochlorite to the filter backwash for algae control. Potential Issues  Need to assess ability to control algae when adding hypochlorite to the surface scrub system or to the clearwell. If not feasible, addition of backwash pumps may be required.  Relocation of the MF system can increase cost and cause potential logistical issues.  Increases near-term cost needed for new membrane filtration building.  Schedule to install a new MF skid is tight to meet rehabilitation timeframe.  Risk of UV non-compliance due to the change in the nature of the Marco Lakes Source water.  While the 50% measured UV transmittance is similar to the values measured during the pilot, the existing lime softener is having difficulty achieving UVT values that are consistently above 70 percent.  Jar testing shows that UVT above 75% would be difficult to achieve with the current treatment system and modifications to the alum addition (including mixing and pH adjustment) may be needed.  Validation of UV equipment at UVT below 70% may be required to ensure continued compliance (units are not currently validated below 70%). Advantages  Eliminates operational issues with existing Zenon system by upgrading to newer and more robust membrane filtration technology.  Eliminates lease cost of equipment that does not provide long-term benefit.  Easier and lower-cost future membrane filtration expansion because new building would already be installed (~$1M).  Would allow 2 mgd of production without lime softening reactor during future maintenance by using direct filtration through LT2 compliant membrane system.  Allows consideration of low-pressure UV systems with lower operating cost.  Eliminate 100,000 gpd of blowdown (potable water to waste) by eliminating the Zenon system with and annual treatment cost of about $60,000.  Operating cost will be lower than Option 1 MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 8 Option 3 – Replace Media Filters with Membrane Filtration Description This option includes rehabilitating only the lime softening system and then replacing both the existing media filters and Zenon system with a new LT2-compliant membrane filtration system. The option also includes installing a new membrane building that is sized for future expansion. The new MF system has been proven to provide more than the current required 3-log Giardia removal which could potentially eliminate the need for Giardia disinfection including chlorine contact time and UV (pending FDEP acceptance). Improvements / Action Items 1. Rehabilitate existing lime softener August-September 2010. 2. Meet with FDEP to discuss rehabilitation and ensure approval of short-term direct filtration treatment using existing filters and long-term approval of MF for minimum 3- log Giardia inactivation without secondary disinfection. 3. Operate existing media filters at low loading rate with direct upstream alum feed to meet summer production requirements. 4. Purchase LT2 compliant 2-mgd membrane filtration skid to replace existing Zenon system and install in a new membrane building.  Pending FDEP approval, this and future MF units could meet full Giardia removal credit without the need for chlorine contact time and UV. 5. Provide space for, or if required install UV that is sized for 0.5-log Giardia inactivation to meet secondary disinfection requirements. 6. Relocate current hypochlorite injection point to MF system feed pipe after exposure of process water to open atmosphere to meet the requirements of the FDEP bird rule. 7. Relocate the ammonia feed point to a minimum of 30 seconds HRT downstream of the hypochlorite injection point after achieving the required 2-log virus inactivation. Potential Issues  Need to verify that FDEP will allow continued operation of media filters without rehabilitation until after 6.7 mgd of membrane filtration is installed next year  Added engineering needed to work out phasing and expansion to eliminate potential increased construction cost or future redesign.  Consistent and permitable near-term 6.7 mgd may require 4 MF trains, thus increasing near-term installed equipment cost.  Increases near-term cost based on design, construction and installation of new membrane filtration system and building.  Will require a larger MF building for future expansion that will be more challenging to fit on the NWTP site. Building size can vary from 50’x60’ to 120’x60’ depending on types of skids, configuration, and layout. MARCO ISLAND FILTRATION AND UV OPTIONS ANALYSIS MARCO FILTRATION AND UV OPTIONS ANALYSIS 4-5-10 9  May require common MF feed tank (or feed clearwell) to equalize flow between the discharge of the lime softening reactor and the feed of the membrane filters. The AP8 skids each have a feed tank that can significantly increase building footprint. Using a common feed tank may be more cost effective.  Need to verify that the existing lime softener can adequately treat recycled MF backwash water. Solids that not removed after multiple recycles can accumulate in the system and eventually impact MF performance. Additional low-cost treatment in the backwash equalization basins may be needed. Advantages  Eliminates the urgent need to provide temporary MF system this summer and reduces total system downtime for rehabilitation.  Would allow NWTP to operate without lime softening reactor during periodic maintenance.  Would allow ready conversion at NWTP from lime softening to membrane softening by providing appropriate pretreated water.  Eliminates lease cost of equipment that does not provide long-term benefit.  May eliminate the need for UV provided FDEP approves MF for full Giardia and Crypto removal credit.  System would be ready for future MF expansion with lowest construction cost and minimal or no engineering (~$1M).  Gain land of filters, clearwell, transfer pumps, and existing control building.  Lower operating cost than current option.  Reduces operational issues associated with lime reactor upset and high turbidity carryover into filters. Filtered water turbidity compliance will not be an issue.  Will produce consistently better finished water quality than existing system.  One filtration system that is easier to operate and automate.  Allocate portion of UV design costs to MF design costs.  Eliminates low UV transmittance issue.  Eliminates issues associated with open filters and need to meet FDEP ‘bird rule’.  Eliminates 100,000 gpd of UF reject flow by eliminating the Zenon system with and annual treatment cost of about $60,000.

Marco Island NWTP Membrane Filtration Improvements Project Overview MARCO MF PROJECT OVERVIEW REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island NWTP Membrane Filtration Improvements Project Overview PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Introduction Marco Island Utilities (MIU) owns and operates two water treatment facilities, the North Water Treatment Plant (NWTP) and the South Water Treatment Plant (SWTP). The NWTP is an aging 6.7 million gallons per day (mgd) conventional lime softening and filtration facility that treats surface water from Marco Lakes. The SWTP is a 6.0-mgd reverse osmosis (RO) facility that desalts brackish water from Mid-Hawthorn Aquifer Wells. Approximately 3 mgd of filtered blend water is transferred from the NWTP to the SWTP to help stabilize the RO permeate and meet the higher demands on the south side of the island. Exhibit 1 shows a process flow diagram of the Marco Island water treatment system including both the NWTP and SWTP. EXHIBIT 1 Proposed NWTP Site Layout Marco Island Membrane Filtration Improvements Project Engineering Report The Marco Island NWTP Membrane Filtration (MF) Improvements Project will improve the operability, reliability and efficiency of the NWTP while working to meet both current and MARCO ISLAND NWTP MEMBRANE FILTRATION IMPROVEMENTS PROJECT OVERVIEW MARCO MF PROJECT OVERVIEW REPORT 12-22-10.DOCX 2 future anticipated regulations. The project will also prepare the NWTP for future expansion up to 10 mgd. Exhibit 2 shows an aerial of the NWTP with a summary of the project components which include:  Install a 6.7 mgd microfiltration system including feed pumps, strainers, backwash pumps, air system, instrumentation/control, and cleaning system in a newly constructed building located on the existing NWTP site  Construct a new consolidated chemical storage and feed area for currently used chemicals (alum, hypochlorite, phosphoric acid, citric acid), as well as a new sodium hydroxide that will be used for MF cleaning  Relocate existing carbon dioxide and ammonia storage and feed systems to new chemical storage area  Install new transfer pumps that will send filtered water to the SWTP for blending  Replace existing lime softening basin internal mechanism with a new mechanism of the same type  Install new yard piping for temporary fill of the existing 4MG tank during construction that will ultimately be used for permanent blend and 4MG tank fill  Modify existing backwash basin to provide solids settling before new backwash recycle pumps transfer the recovered water to lime reactor inlet  Add instrumentation and control systems to automate new and existing chemical feed systems, MF system, and transfer pumps.  Modify disinfection approach to achieve the full required Giardia, cryptosporidium, and virus inactivation after exposure to air without chloramine contact time.  Remove from service and demolish existing sulfuric acid feed system, granular media filters, clearwell, transfer pumps, old high service pump station, old control room, electrical shed, and finished water pipe  Reallocate existing 0.5-MG tanks for use at the Reclaimed Water Production Facility (RWPF)  Repower existing lime reactor, backwash basin pumps, and solids handling equipment from new MF building electrical room The MF Improvements project will simplify the overall process as demonstrated by the process flow diagrams presented in Exhibit 3. As the diagrams show, the only new components of the NWTP will be the MF system, transfer pumps, and sodium hydroxide system used for MF cleaning. Modifications will include a change in disinfection approach that takes advantage of the enhanced filtration and integrity monitoring of the MF system and the refurbishing the lime reactor by installing new equipment that is the same as the existing equipment. The primary challenge of this project will be obtaining appropriate disinfection credit for the microfiltration system which has integrity monitoring that is compliant Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) requirements. Current Florida Department of Environmental Protection (FDEP) rules do not address the advanced removal capabilities of the microfiltration system that have been demonstrated in third- party validation testing and have been accepted by the United States Environmental Protection Agency (USEPA) and other state agencies. MARCO ISLAND NWTP MEMBRANE FILTRATION IMPROVEMENTS PROJECT OVERVIEW MARCO MF PROJECT OVERVIEW REPORT 12-22-10.DOCX 3 Section 62-550.817 (2)(b) FAC discusses the Giardia and virus removal and inactivation requirements for subpart H systems treating surface water. The current language indicates that “Systems providing reverse osmosis, ultrafiltration, or nanofiltration shall provide sufficient disinfection to achieve a minimum of 0.5-log Giardia lamblia cyst and 2-log virus inactivation to supplement membrane filtration treatment.” This language, written before the LT2ESWTR and the USEPA membrane filtration guidance manual (MFGM), does not address the use of microfiltration, nor the implementation and adoption of direct integrity testing to directly and reliably demonstrate that MF systems greater than 4.5-log Cryptosporidium and Giardia removal by both microfiltration and ultrafiltration membrane systems. Information on several operating facilities in North America have demonstrated that these membrane filtration systems can reliably exceed the 3-log Giardia and Crypto removal requirements of the SWTR and LT2ESWTR. Therefore, MIU is proposing that FDEP permit the selected microfiltration system for full 3-log Giardia and 3-log Crypto removal in accordance with the MFGM. This will require a change or an exemption to the current rule as described in 62-550.817 (2)(b) FAC. MF has been classified by the USEPA as a ‘best available technology’ (BAT) for meeting the Cryptosporidium removal requirements of the LT2ESWTR. As such it is also a BAT for removal of the larger-sized Giardia. Using the proposed design criteria of this project, following the guidelines of the MFGM and having selected a MF product whose performance (for Crypto and Giardia removal) has been validated through third-party testing (e.g., California Department of Public Health certification testing) should provide a reliable and permitable system. To provide a safety factor with respect to compliance with LT2ESWTR and SWTR, CH2M HILL proposes to design MF system such that during operation, it will to achieve >4-log Giardia/Crypto removal 95 percent of the time and >3.5- log Giardia/Crypto removal 100 percent of the time. The integrity of the MF system with respect to removal of these pathogens will be demonstrated through continuous indirect integrity testing and daily direct integrity testing in accordance with chapters 3 and 4 of the MFGM.

MIU wishes to remain proactive in meeting the potential Cryptosporidium inactivation requirements of this rule, as well as current Giardia and virus removal/inactivation requirements of the SWTR and those further mandated by FDEP (i.e., ‘bird rule’). At present, the NWTP achieves the 2-log virus and 0.5-log Giardia inactivation requirements of the bird rule by using chloramines to provide sufficient CT in the existing finished water storage tanks. However, MIU desires to use these tanks to provide more storage at the NWTP and for equalization at the adjacent Reclaimed Water Production Facility. FDEP Requirement for Filter Rehabilitation The FDEP conducted routine inspections of the NWTP in 2009 and identified several old components that were corroded or deteriorated. Several 40+ year-old structural components of the existing filters pose a safety risk to operations staff, and other corroded filter components have begun to impact treated water quality. FDEP therefore mandated that MIU make improvements to the filters and lime softening reactor. These improvements are anticipated to cost $1.6M ($1.2M for the filters) and are expected to take up to 2 months to complete. The NWTP will not be able to produce the water needed to meet finished water demands during this rehabilitation without a temporary filtration system that is expected to cost approximately $275,000. Zenon System Failure The existing Zenon membrane filtration system, installed in 1998 and which representing 20 percent of the total filtration capacity at the NWTP, is aging and is showing signs of imminent failure. Currently the system is operating at significantly reduced capacity. To restore structural and performance integrity, a minimum of 50 percent of the membrane cassettes must be replaced, and the steel tank requires significant refurbishment or replacement. Estimated cost for repair and/or replacement is a minimum of $560,000 and must be completed in the near future to maintain the current NWTP capacity of 6.7 mgd. Repairing the Zenon system will extend the life of the system by approximately 3 years, but will not ensure compliance with the upcoming LT2ESWTR. UV System Cost Impact from Source Water Quality Change CH2M HILL conducted an initial investigation of UV for disinfection at the NWTP in August 2009 using the results of the membrane filtration pilot testing conducted in 2008. Pilot testing showed that UV could meet the new regulations efficiently. CH2M HILL recommended that MIU implement UV disinfection in order to comply with both the requirements of the LT2ESWTR and FDEP bird rule. Recent changes in Marco Lakes water quality prompted CH2M HILL to conduct additional testing during March 2010 to identify the impact to the proposed UV system and if changes to existing NWTP treatment could improve UV efficiency. The testing results indicated that the water quality changes would significantly reduce the UV efficiency and that changes to NWTP operation would result in little improvement. The lower UV system efficiency would MARCO ISLAND NWTP MEMBRANE FILTRATION IMPROVEMENTS PROJECT OVERVIEW MARCO MF PROJECT OVERVIEW REPORT 12-22-10.DOCX 8 double the UV system footprint and O&M cost and would not meet the FDEP bird rule without continued use of the 0.5-MG storage tanks. UV system construction cost was expected to increase by at least $600,000 up to a total of $2.0M. Backup for the Lime Softening Reactor and Filters During Annual Maintenance MIU needs a treatment system that can meet current regulations, as well as the LT2ESWTR during annual maintenance of the lime softening reactor and filters. A new membrane filtrations system is a cost-effective option that can meet regulations when the lime softening reactor is down for maintenance and be maintained without reducing system capacity. Future Membrane Filtration Expansion MIU is planning to expand the NWTP by 4 mgd in 2013 to meet increasing finished water demand on the island. An expansion evaluation conducted by CH2M HILL in 2007 identified direct filtration of the NWTP Marco Lakes source water using a membrane filtration as a cost effective expansion option. MIU and CH2M HILL conducted a membrane filtration pilot study between January and August of 2008 to identify the feasibility and cost of treating the Marco Island NWTP source water with membrane filtration. A MF pilot unit supplied by Pall Corporation was used for the testing and displayed excellent performance. Based on the results of the pilot study, the membrane filtration equipment cost was estimated at $1.4M. After installing a building and other related process components, the anticipated cost for the expansion was estimated at $7M. Based on all of these considerations, MIU and CH2M HILL have identified various processes for meeting finished water treatment goals and the more stringent state and federal regulations. After a detailed evaluation, membrane filtration followed by the existing lime softening process has been selected as the preferred treatment that would provide the best value while meeting all the goals and regulations. Summary of MF System Design Criteria  Use of MF product whose membrane fiber and module characteristics comply with the requirements of the LT2ESWTR  Meet the intent of the MFGM with respect to MF system product quality control/quality assurance testing, direct and indirect integrity testing and MF system design  6.7-mgd minimum filtered water flow rate with one fully redundant MF train  Automated direct integrity testing of each membrane train on a 24-hour basis to verify a minimum 3.5-log cryptosporidium and 3.5-log Giardia removal that exceeds current and future requirements  Disinfection of the MF filtrate using free chlorine to meet the FDEP requirement for 2-log virus inactivation when MF is used following lime softening or 3-log virus inactivation when MF directly treats Marco Lakes water  Minimum design recovery rate of 95 percent with backwash equalization, treatment and recycle to the inlet of the lime reactor  Design flux of 65 gfd as established through pilot testing based on direct treatment of Marco Lakes water (most challenging MF feed water quality) MARCO ISLAND NWTP MEMBRANE FILTRATION IMPROVEMENTS PROJECT OVERVIEW MARCO MF PROJECT OVERVIEW REPORT 12-22-10.DOCX 9  Automatic (PLC-controlled) operation of all MF system functions (filtration, backwash, chemically-enhanced backwash, direct integrity testing and clean-in-place)  On-line laser turbidimeter for continuous, indirect integrity monitoring of filtrate from each MF train TECHNICAL MEMORANDUM 3. Marco Island NWTP Membrane Filtration Improvements Project Water Quality MARCO MF PROJECT WQ REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island NWTP Membrane Filtration Improvements Project Water Quality PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Source Water The NWTP source water comes from the Marco Lakes located approximately 10 miles north of Marco Island. The source for the Marco Lakes is storm water runoff from adjacent Henderson Creek with some influence from local groundwater. The majority of the year, water from Henderson Creek flows into the Marco Lakes through an embankment which significantly reduces turbidity. However MIU occasionally must open a weir gate between Henderson Creek and Marco Lakes when lake levels drop and more flow is needed. MIU also uses Aquifer Storage and Recovery (ASR) wells to store excess Marco Lakes water during the wet season for use during the dry season. MIU injects filtered Marco Lakes water into seven Floridan Aquifer wells during the wet season, and then recovers this water during the dry season. The recovered water is blended with the surface water or used alone to feed the NWTP in the dry season. The recovered ASR well water is influenced by the brackish Floridan aquifer groundwater having elevated levels of chloride and sulfate. Exhibit 1 presents the range of feed water quality. The feed water quality can vary due to seasonal changes in Marco Lakes as well as the use of recovered water.

Actual TOC removal may be greater depending on selected process. Finished Water Quality Goals The treated water after the improvements project must improve upon existing finished water quality. The finished water quality shall meet current and proposed future regulatory requirements including FDEP primary and secondary drinking water standards, USEPA S2DBPR and the LT2ESWTR. Exhibit 2 presents MIU’s anticipated finished water quality goals based on these regulatory requirements as well as MIU specific goals for aesthetic-based parameters. The raw Marco Lakes water is high in color, hardness, and total organic carbon (TOC) including disinfection byproduct (DBP) precursors. The surface water may also contain pathogens that require removal or inactivation. The high concentrations of sulfate and chloride may be contributing to copper corrosion problems in the distribution system on the north end of the island. The improved treatment process must effectively address these target constituents to meet the desired water quality goals. The finished water quality must be stable (non-corrosive) with a pH near 8.8, total alkalinity above 35 mg/L as CaCO3, and total hardness between 100 to 120 mg/L as CaCO3. The treatment process should minimize increases in sulfate and chloride, or even reduce them in order to control copper corrosion. MARCO ISLAND NWTP MEMBRANE FILTRATION IMPROVEMENTS PROJECT WATER QUALITY MARCO MF PROJECT WQ REPORT 12-22-10.DOCX 3 The finished water must meet the S2DBPR by achieving 30 percent TOC removal and maintain a TTHM concentration below 80 g/L and a HAA5 concentration below 60 g/L at all points within the distribution system.

Marco Island NWTP Membrane Filtration System MARCO MF PROJECT MEMBRANE REPORT 12-22-10.DOC 1 TECHNICAL MEMORANDUM Marco Island NWTP Membrane Filtration System PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Background During the treatment alternatives evaluation phase of this project, Marco Island Utilities (MIU) identified low-pressure membrane filtration as one of the processes to meet the current and upcoming federal and state regulations for the NWTP. The membrane filtration process will meet the requirements of the Florida Department of Environmental Protection (FDEP) “bird rule” and the US Environmental Protection Agency (USEPA) Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). Membranes offer several advantages over other filtration technologies, with the superior and absolute particle removal barrier a key consideration in its selection. A low-pressure membrane filtration process provided by Pall Water Processing Inc. (Pall) of Cortland, NY was among one of the processes that were piloted at the NWTP. The 8-month pilot study was conducted in 2008 and the results of the study were summarized in The Marco Island Pilot Report dated January 6, 2010. During this study, the feasibility of the low- pressure membrane process in meeting treatment goals was demonstrated. As part of this study, the operating parameters such as flux, backwash intervals, and chemical cleaning regimes were also established. The NWTP source water quality has been degrading because of increased groundwater influence, and because the South Florida Water Management District is redirecting additional stormwater into the Henderson Creek. Therefore, low-pressure membrane filtration process has been selected as the most cost-efficient way to upgrade the plant to meet treatment and production objectives. MIU selected a membrane system provided by Pall. Pall will be providing a low-pressure membrane system with all the necessary ancillary components for the system in addition to the microfiltration treatment trains. The details of the system will be outlined in this technical memorandum. MARCO ISLAND NWTP MEMBRANE FILTRATION SYSTEM MARCO MF PROJECT MEMBRANE REPORT 12-22-10.DOC 2 Membrane Filtration System The membrane filtration system generally consists of the following major systems:  Membrane Feed Tank  Membrane Feed Pumps  Pre-Filter Strainers  Membrane Filter Racks  Reverse Filtration (RF) System (i.e. backwash) o RF pumps o Compressed Air Scour System  Membrane Integirty Testing Air System  Chemical Cleaning System for Clean-in-Place/Enhanced Flux Maintenance (EFM) A process flow diagram for the NWTP is presented in Exhibit 1that includes the systems listed above. EXHIBIT 1 NWTP Process Flow Diagram Marco Island Membrane Filtration Improvements Project Engineering Report The raw water feed for the plant will be Marco Lakes which will be pre-treated with the refurbished lime softening reactor before it is introduced to the Membrane Filtration trains. Lime softening followed by membrane filtration was selected as the ultimate treatment train that would provide the best value to MIU while meeting all the finished water treatment goals of complying with the current federal and state regulations. MARCO ISLAND NWTP MEMBRANE FILTRATION SYSTEM MARCO MF PROJECT MEMBRANE REPORT 12-22-10.DOC 3 Membrane System Components The system components are presented in Exhibit 2 below: EXHIBIT 2 Membrane System Components Design Criteria Marco Island Membrane Filtration Improvements Project Engineering Report Description Value Number of membrane trains 4(1) (3 Duty, 1 Standby) (+ space for 2 additional trains in the future) Number of membrane modules populated per train 72 Number of membrane spaces per train 80 Total number of populated membrane modules 288 (216 Duty, 72 Standby) Number of membrane feed pumps 3 (2 Duty, 1 Standby) Number of pre-filter strainers 3 (2 Duty, 1 Standby) Pre-filter strainer mesh size 300 µm Number of RF pumps 2 (1 Duty, 1 Standby) Air Compressors/Receivers 2 (1 Duty, 1 Standby) Membrane Cleaning Chemicals Sodium hypochlorite Sodium hydroxide Citric acid CIP/EFM Circulation Pumps 2 (1 Installed, 1 shelf spare) CIP/EFM Batch Tanks 2 (1 acid, 1 base) (1) Under normal operation mode all trains will be operational.

Each train will have space to install 10% more membranes in case filtrate production can’t be met due to changes in operational conditions such as the raw water source. The membrane system is sized to account for filtrate usage for backwashes, chemical cleans, and chemical cleans and down time for integrity testing. Piping and all ancillary equipment is sized to enable future expansion. The system has been designed to be able to install two additional trains for an ultimate net filtration capacity of approximately 10 million gallons per day. The system is designed based on the parameters set during the 2008 membrane pilot study. Characteristics of the membrane product and detailed productivity design criteria of the membrane treatment trains are provided under separate headings in this technical memorandum. Membrane Feed Tank A membrane feed tank will be installed between the membrane filter trains and the existing Lime Softening Reactor. The tank has a capacity of 15,000 gallons and is provided to equalize flow from the lime softening process to maintain uniform water quality into the membrane filters. The membrane feed tank is sized for 3 minutes detention at maximum flow. Pre-Filter Straining System The 300 micron pre-filter strainers are provided with two duty and a spare unit, each dedicated to a feed pumps.

The following is a description of the system operation provided by Pall: 1. Forward Filtration (FF): The feed pump draws water from the membrane feed tank and pumps it through the membrane filters through the feed port at the bottom of the modules. The filtrate exits the filtrate port at top end of the modules. 2. Reverse Filtration and Air Scrub (RF & AS): As water is filtered, rejected particulate accumulates on the membrane fiber’s surface. The effect is flow restriction in the module increasing the transmembrane pressure (TMP.) After a user defined total filtered flow volume, he module racks will go through a combined reverse filtration (RF) and air scrub (AS) cycle that backwash the filters. Filtrate is pumped from the reverse side of the membrane fibers (lumens) at a fixed filtration rate and while air is injected into the modules on the feed side of the fibers. All discharge during the RF & AS is sent out the upper drain. The combined water-air flow creates strong turbulent and shearing force to dislodge dirt deposits on the membrane surface. The filtrate for the RF cycle will be pumped from the main filtrate header after the membrane trains.The RF ans AS cycle is anticipated to be automatically initiated every 30 minutes. 3. Reverse Flush (FL): This process follows an AS to flush waste out of the module. During a FL, the RF pump is used to pump additional filtered water without air through the fibers and out the upper drain to waste. 4. Enhanced Flux Maintenance (EFM): At a user defined flow volume which is anticipated to be at least 3 days depending on feed water characteristics, the system will stop while in forward filtration mode. During the EFM process, the feed side of the system is drained and filtrate is then pumped from the permeate header to the CIP/EFM tank and heated via a submerged water heater. Chemical (typically chlorine) is injected into the heated water and the warm solution is then recirculated for 30 minutes through the system on the feed side of the filter and back to the CIP/EFM tank. The solution is then drained and the system is flushed using a standard AS and FL. The EFM procedure functions to extend the interval between the full chemical clean-in-place. 5. Clean-In-Place (CIP): Approximately once a month, a more thorough chemical cleaning is required. The CIP is a 2 step process. The first step consists of circulating a 1% sodium hydroxide and 0.1% sodium hypochlorite solution on the feed side of the modules for 3 hours. The second step consists of circulating a 2% citric acid solution on the feed side of the module for 2 hours. An on-board computer and PLC control the operation of the system. Critical operational parameters are logged continuously and are recorded automatically on the system computer’s hard drive. The real-time data is used for operation optimization and troubleshooting. Operational Control Parameters The system includes both direct and continuous indirect membrane integrity testing methods in accordance with the USEPA Membrane Filtration Guidance Manual. Key operational control parameters are presented in Exhibit 6 below.

This is anticipated the RL/AS will be initiated approximately every 30- 40 minutes. RF waste (i.e. backwash) and flush (i.e. filter-to-waste) contains no membrane cleaning chemicals and shall be discharged to the NWTP backwash recovery basins. Chemical Cleaning –EFMs are automatically triggered by a user-configured TMP setpoint. Chemical solutions can be heated to increase the effiencies of the cleans. EFMs are anticipated approximately every 3 days depending on source water characteristics. CIPs are manually initiated by operations staff and are anticipated approximately once a month. CIP will target restoring membrane permeability. All CIP spent waste will be sent directly to sanitary sewer. Water softening is not required for process water. TECHNICAL MEMORANDUM 5. Marco Island NWTP MF Improvements Project Disinfection Design MARCO MF PROJECT DISINFECTION REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island NWTP MF Improvements Project Disinfection Design PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Background During the treatment alternatives evaluation phase of this project, Marco Island Utilities (MIU) identified lime softening, low-pressure membrane filtration, and chlorination as the preferred treatment train to meet the current and upcoming federal and state regulations for the NWTP. This train will meet the requirements of the Florida Department of Environmental Protection (FDEP) “bird rule” and the US Environmental Protection Agency (USEPA) Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). Membrane filtration offers several advantages over other filtration technologies, with the superior and absolute particle removal barrier a key consideration in its selection. In conjunction with lime softening and low pressure membranes, chlorine disinfection will be used to meet disinfection requirements. Disinfection System The disinfection system has been dictated by current drinking water regulations. The regulatory requirements that impact disinfection requirements for the NWTP include:  FDEP rules require 4-log virus inactivation after exposure to air  SWTR requires 3-log Giardia inactivation  ESWTR required 2-log cryptosporidium removal Virus and Giardia Removal/Inactivation The Surface Water Treatment Rule (SWTR), promulgated in 1989, seeks to prevent waterborne diseases caused by viruses, such as Legionella and Giardia lamblia. To reduce occurrence of these microbes in drinking water, the SWTR requires that water systems filter and disinfect water from surface water sources, and from groundwater sources under the direct influence of surface water. The SWTR includes criteria requiring filtration and procedures for determining whether filtration and disinfection systems are required. Water treatment plants must achieve at least a 3 log (99.9 percent) removal or inactivation of Giardia and a 4 log (99.99 percent) removal MARCO ISLAND NWTP MF IMPROVEMENTS PROJECT DISINFECTION DESIGN MARCO MF PROJECT DISINFECTION REPORT 12-22-10.DOCX 2 or inactivation of viruses. Removal credit is given to systems that provide adequate filtration. The remainder of the credit must be achieved through chemical disinfection (that is, chlorine treatment) that inactivates the microorganism. Florida Department of Environmental Protection (FDEP) rules have the additional restriction that the 4-log virus removal/inactivation must occur downstream of any exposure to air. The SWTR allows a 2.5 log Giardia credit and a 2.0 log virus credit for a well-operated conventional treatment plant. Exhibit 1 provides a summary of filtration processes, along with the associated Giardia and virus removal credits granted in the FDEP rules. Additional disinfection credits must be achieved through chemical disinfection for microorganism inactivation. To help utilities determine if inactivation requirements are being met, the SWTR establishes and references “CT Tables” to determine associated chemical disinfection credits. The CT tables are a function of the water pH, temperature, chlorine dose, and the type of baffling or short circuit factor. EXHIBIT 1 Typical Removal Credits for Various Treatment Technologies Marco Island Membrane Filtration Improvements Project Engineering Report Process Giardia Removal Virus Removal Conventional treatment 2.5-log 2.0-log Direct filtration 2.0-log 1.0-log Slow sand filtration 2.0-log 2.0-log Diatomaceous earth filtration 2.0-log 1.0-log Alternative (membranes, bag filters, cartridge filters) Systems must demonstrate the log removal of the alternative filtration method by pilot study or other means Cryptosporidium Removal/Inactivation The Long Term 2 Enhanced SWTR (LT2SWTR) was promulgated in 2006, and builds on previous surface water treatment regulations. As with previous rules, LT2ESWTR goals were to improve public health protection through the control of microbial contaminates by focusing on systems with elevated Cryptosporidium risks, and to prevent significant increase of microbial risk that might otherwise occur when systems implement the Stage 2 Disinfectant and Disinfection Byproducts (DDBP) Rule. LT2ESWTR recognizes that systems may require additional protection against Cryptosporidium, and that such decisions should be made on a system-specific basis. System source water Cryptosporidium monitoring is required. Monitoring results are used to classify systems in different categories, or bins, based on Cryptosporidium levels found in source water. All systems are required to achieve 2-log removal and additional removal may be required based on the results of source water monitoring. Exhibit 2 provides a summary of bin classifications and total removal or inactivation requirements based on the number of cysts found in source water.

EXHIBIT 3 NWTP Process Flow Diagram Marco Island Membrane Filtration Improvements Project Engineering Report Giardia/Cryptosporidium Removal Design Microfiltration membranes sieve particles from water based on pore size. Microfiltration systems have been shown to have log-removal levels for Giardia and cryptosporidium cysts above 4-log, because the cysts are larger than the membrane pore size. The Appendix provides validation testing results for the Pall MF system demonstrating greater than 4-log removal of the smaller Cryptosporidium cyst, as well as regulatory acceptance documents. MARCO ISLAND NWTP MF IMPROVEMENTS PROJECT DISINFECTION DESIGN MARCO MF PROJECT DISINFECTION REPORT 12-22-10.DOCX 4 Section 62-550.817 (2)(b) FAC discusses the Giardia and virus removal and inactivation requirements for subpart H systems treating surface water. The current language indicates that “Systems providing reverse osmosis, ultrafiltration, or nanofiltration shall provide sufficient disinfection to achieve a minimum of 0.5-log Giardia lamblia cyst and 2-log virus inactivation to supplement membrane filtration treatment.” This language, written before the LT2ESWTR and the USEPA membrane filtration guidance manual (MFGM), does not address the use of microfiltration, nor the implementation and adoption of direct integrity testing to directly and reliably demonstrate that MF systems greater than 4.5-log Cryptosporidium and Giardia removal by microfiltration membrane systems. Information on several operating facilities in North America have demonstrated that membrane filtration systems can reliably exceed the 3-log Giardia and Crypto removal requirements of the SWTR and LT2ESWTR. Therefore, MIU is proposing that FDEP permit the selected microfiltration system for full 3-log Giardia and 3-log Crypto removal in accordance with the MFGM. This will require a change or an exemption to the current rule as described in 62-550.817 (2)(b) FAC that provides no credit beyond conventional filtration for microfiltration. MF has been classified by the USEPA as a ‘best available technology’ (BAT) for meeting the Cryptosporidium removal requirements of the LT2ESWTR. As such it is also a BAT for removal of the larger-sized Giardia. Using the proposed design criteria of this project, following the guidelines of the MFGM and having selected a MF product whose performance (for Crypto and Giardia removal) has been validated through third-party testing (e.g., California Department of Public Health certification testing) should provide a reliable and permitable system. To provide a safety factor with respect to compliance with LT2ESWTR and SWTR, CH2M HILL proposes to design MF system such that during operation, it will to achieve >4-log Giardia/Crypto removal 95 percent of the time and >3.5- log Giardia/Crypto removal 100 percent of the time. The integrity of the MF system with respect to removal of these pathogens will be demonstrated through continuous indirect integrity testing and daily direct integrity testing in accordance with chapters 3 and 4 of the MFGM. Log reduction value (LRV) is the metric for evaluating membrane performance. LRV is a theoretical number calculated based on the plant flow, the hydraulic configuration of the membranes, and the amount of flow that is by-passing the membrane. Feed water may by- pass the membrane due to breaks in the membrane fibers. LRV is calculated for the membrane system and reported in the SCADA System. A direct integrity warning point will be set at a LRV less than or equal to 4.0. A direct integrity shutdown set point will be set at a LRV less than or equal to 3.5. The proposed NWTP disinfection design is claiming 3.0-log removal for the membrane system, which lower than the shut down set point. Virus Removal/Inactivation Design The membrane system will provide adequate Giardia and Cryptosporidium removal, but virus inactivation will need to be achieved through multiple barriers. NWTP will receive 2- log virus removal credit from lime softening plus filtration; the remaining 2-log required for a total of 4-log removal/inactivation will be through free chlorine chlorination. If bypassing the lime reactor during normal maintenance, the NWTP can continue to add alum coagulant to achieve direct filtration which would provide 1-log virus removal per FDEP rules. The MARCO ISLAND NWTP MF IMPROVEMENTS PROJECT DISINFECTION DESIGN MARCO MF PROJECT DISINFECTION REPORT 12-22-10.DOCX 5 remaining 3-log inactivation when membrane filtering in-line coagulated would be achieved by free chlorine contact time. Virus inactivation is required after lime softening filtration, the last point of the process that is open to the air, due to the FDEP ‘bird rule.’ The level of inactivation is presented in tables published by the EPA and is based on CT (the required contact time x concentration of free chlorine), water temperature, and pH. The required contact time for disinfection has been evaluated as the time between the chlorine addition and the ammonia addition. Exhibit 4 shows the piping located in the Membrane Facility that was used for disinfection calculations. Exhibit 5 summarizes the chlorine disinfection design parameters. The hydraulic retention time in the pipe between the feed tank and the ammonia injection point is 1.05 minutes using the shortest flow path displayed in Exhibit 4 and the maximum flow shown in Exhibit 5. This represents the minimum contact time available in the line and given the 1.0 baffling factor, the minimum T10. The resulting 3.15 CT is adequate to provide the needed 3 mg/L- min CT for 3-log virus inactivation at the minimum 15C temperature and 3.0 mg/L chlorine residual at the normal operating pH that is less than 9.0. To ensure continued compliance, flow through the membrane system will be continuously monitored and a new total chlorine residual analyzer will be located downstream of the ammonia injection point.

Chlorine will be dosed as sodium hypochlorite. The bulk storage tanks and the feed pumps will be relocated as part of this upgrade.

Marco Island NWTP MF Improvements Project Chemical Storage and Feed Systems MARCO MF PROJECT CHEMICAL REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island NWTP MF Improvements Project Chemical Storage and Feed Systems PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Introduction The existing chemical storage and feed systems at the Marco Island North Water Treatment Plant (NWTP) are located in various locations around the WTP site and are manually controlled. Many of these chemical systems must be relocated to make room for the new membrane filtration (MF) building, as well as to move them from future demolition locations. The NWTP MF improvements project includes constructing a new bulk chemical and storage area that will serve to consolidate all of the new and existing chemicals on the NWTP site. The benefits of centralizing the chemical bulk storage and feed systems include the following:  Simplify chemical delivery by creating one fill station in an easily accessed location  Improve operations by automating chemical feed, adding SCADA monitoring of tank levels, and centralizing chemicals near the treatment facilities for easy inspection  Promote safety by eliminating tote/drum handling, providing more accessible eyewash/safety shower stations, improving lighting, and improved bulk tank protection/containment The chemical system improvements associated with this project fall into the following categories:  Relocation of bulk storage and feed systems (carbon dioxide, alum, sodium hypochlorite, phosphoric acid, citric acid)  Relocation of application point (ammonia, sodium hypochlorite, citric acid, phosphoric acid)  New chemical associated with MF cleaning processes (sodium hydroxide) The new and relocated chemical systems at the NWTP and their primary uses are listed in Exhibit 1.

MARCO ISLAND NWTP MF IMPROVEMENTS PROJECT CHEMICAL STORAGE AND FEED SYSTEMS MARCO MF PROJECT CHEMICAL REPORT 12-22-10.DOCX 3 Citric Acid Citric acid is a weak organic acid. It is the most frequently used acid in membrane cleaning, since it is less hazardous than mineral acids such as hydrochloric or sulfuric acid. The acid works well on inorganic fouling contaminates and acts as a chelating agent. Sodium Hydroxide Sodium hydroxide is a reactive chemical used to increase the pH of the MF CIP cleaning solution to higher than pH 12. The reactivity of sodium hydroxide requires special materials for storage tanks (fiberglass reinforced plastic resin such as Derakane 411), piping, feed pumps and instrumentation. In the 50 percent concentration form, sodium hydroxide tanks and feed lines should be equipped with heat tracing and insulation to maintain acceptable temperature ranges for the chemical. Sodium hydroxide also requires special building construction and safety equipment including chemical containment, fire sprinklers, chemical suits, and safety showers. Phosphoric Acid (Orthophosphate) Treated water is typically aggressive (tendency to dissolve calcium carbonate) and must be conditioned prior to being introduced into the distribution system to prevent corrosion of piping. Orthophosphate is one method of corrosion control that promotes the formation of calcium phosphate protective scale on distribution system piping. Orthophosphate has also been proven to reduce lead, copper and some iron corrosion in distribution systems The conversion of the orthophosphate species in the water between H3PO4 to H2PO4- and HPO4-2 provides some additional buffering capacity to the finished water to stabilize pH. Orthophosphate is typically added in the form of phosphoric acid, which is a low-cost alternative to proprietary forms. The reactivity of phosphoric acid requires special materials for storage tanks, piping, feed pumps and instrumentation. Phosphoric acid also requires special building construction and safety equipment including chemical containment, fire sprinklers, chemical suits, and safety showers. Sodium Hypochlorite Sodium hypochlorite is a reactive chemical used to provide residual disinfection inside the distribution system and is typically available with an active concentration between 5 and 15 percent, 12 percent solution being the most common. In finished water treatment, when sodium hypochlorite is added to the water, two substances form, hypochlorous acid and the less active hypochlorite ions. Water pH determines which form is more predominant. Sodium hypochlorite is highly unstable and decomposes slowly over time into chlorine gas, oxygen gas and sodium chlorate. The reaction speeds up at temperatures above 40 degrees Fahrenheit. Sodium hypochlorite should not be stored for more than 30 days and it should be kept in a cool, dark and dry area. The reactivity of sodium hypochlorite requires special materials for storage tanks, piping, feed pumps and instrumentation. Sodium hypochlorite also requires special building MARCO ISLAND NWTP MF IMPROVEMENTS PROJECT CHEMICAL STORAGE AND FEED SYSTEMS MARCO MF PROJECT CHEMICAL REPORT 12-22-10.DOCX 4 construction and safety equipment including chemical containment, fire sprinklers, chemical suits, and safety showers. Treatment Process Description Exhibit 3 shows the existing process flow diagram with current chemical application points, as well as the process flow diagram after the installation of the new MF system. The chemical application points will remain the same or will be slightly modified as described below.  Alum, lime and carbon dioxide application points will remain unchanged.  Sodium hypochlorite will continue to be added downstream of the lime softening reactor, but the application point will be moved to just upstream of the membrane feed tanks. This will allow credit for virus inactivation and comply with the FEDP ‘bird rule’, while reducing contact time that can increase DBP formation.  The Ammonia application point will be moved downstream of the new membrane filters to provide free chlorine contact time for virus disinfection. The residence time in the membrane filters is much shorter than the existing granular media filers, which allows the ammonia to be added downstream of the filters without increasing DBP formation.  Phosphoric acid will be added downstream of the new membrane filters, which is similar to its current application point.  The new membrane system will continue to use hypochlorite and citric acid during cleaning cycles.  Sodium hydroxide will be added to the new MF system cleaning process.

Marco Island NWTP MF Improvements Transfer Pumping Design MARCO MF PROJECT TRANSFER PUMP REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island NWTP MF Improvements Transfer Pumping Design PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Background Increasing well salinity is reducing the reliability of the RO process at the South Water Treatment Plant (SWTP) and if not carefully managed may ultimately reduce the current 6 mgd capacity. In order to preserve the existing brackish resource for peak day demands, Marco Island Utilities has incorporated expanded surface water treatment into its 10-year water resources and treatment plan. Part of this plan includes increasing the capacity of the treated surface water that can be transferred from the NWTP to the SWTP. The ongoing Marco Island South Water Treatment Plant Tank project includes switching the use of the existing 12-inch blend line and the 16-inch concentrate line that run between the NWTP and SWTP. Once converted, the larger 16-inch blend line will have the expanded capacity to transfer more than 5 mgd of treated surface water from the NWTP to the SWTP for blending with RO permeate. It should be noted that the 16-inch and 12-inch pipelines have no existing connections to the existing distribution system. The existing transfer pumps are aging converted higher service pumps that are maintenance intensive and inefficient for the blend transfer operation. Therefore this project includes adding new transfer pumps to the MF building that are sized for the 2-5 mgd of design blend flow. The new transfer pumps will be constructed within the new membrane filtration building and will be sized based on the flow capacity of the new 16-inch blend water main and the new system hydraulic head between the NWTP and SWTP. Variable frequency drives (VFDs) will be provided with new transfer pumps for flow control flexibility to the SWTP. Transfer Pump Design The new transfer pump design is to install two transfer pumps (1 duty & 1 standby) within the new membrane filtration building in-line downstream of the new membrane filtration trains. The transfer pumps will discharge into a new 16-inch blend water main that will convey water from the membrane filtration facility to an existing connection point with the 16-inch blend water main to the SWTP. The connection point is near the intersection of E. Elkcam Cir. and Windward Dr. The initial membrane filtration facility configuration will vary slightly from the proposed future configuration. In the initial configuration, the suction will be from the filtrate header which will be hydraulically linked to the existing 4-MG ground storage tank fill stand pipe. In the future configuration, the membrane filtration MARCO ISLAND NWTP MF IMPROVEMENTS TRANSFER PUMPING DESIGN MARCO MF PROJECT TRANSFER PUMP REPORT 12-22-10.DOCX 2 trains will be operated from two separate feed water supplies – Lime Softened Water & Raw Water. The membrane filtration trains will then be valved to separate the feed and filtrate headers based water supply source. The transfer pumps will be downstream of the raw water membrane filtration trains which will no longer be hydraulically linked to the existing 4-MG ground storage tank. The pump suction will be from the raw water filtrate header which will have a residual pressure of approximately 20 feet (8.7 psi). This filtrate residual pressure will be controlled by the membrane filtration feed pumps. Currently, the existing NWTP high service pumps discharge to the 12-inch blend water main to the SWTP and to two water mains (one 12-inch and one 16-inch) that leave the NWTP along Windward Drive, connecting to the distribution system near the intersection of Windward Drive and Elkcam Circle. These existing pumps will remain in service throughout the construction of the new membrane filtration facility. New Transfer Pump Selection The basis of design of the new SWTP transfer pumps is as follows:  The maximum pump size shall be based on the available capacity in the existing 16-inch blend water main. The maximum practical pumping velocity in the 16-inch pipeline is 6 feet per second, therefore the maximum recommended pumping rate is 5.5 MGD (3,800 gpm)  The pumps will be sized for both initial and future membrane filtration configurations. A high head and low head scenario will also be considered for each configuration. The high head scenario is based on the SWTP RO train in operation and blending with the NWTP blend water. The low head scenario assumes the RO trains are off. The selected pump will be evaluated under initial/low-head, initial/high-head, future/low head, and future/high-head conditions as described below.  The pump’s best efficiency point (BEP) shall be between of the low-head and high head operating points. The selected pump will be evaluated under initial/low-head, initial/high-head, future/low head, and future/high-head conditions as described below. The piping system from the new transfer pumps to the SWTP was modeled using a hydraulic modeling program (AFT Fathom) to determine system head conditions at initial/low-head, initial/high-head, future/low-head, and future/high-head conditions. The system curves for each of the four scenarios are presented in the chart below. A Peerless horizontal split case model 8AE15 with a 12.32” impeller diameter is recommended. This pump’s 100% and 50% speed curves are also shown in Exhibit 1. The fundamental control strategy for SWTP blend water transfer service is to operate the pumps to maintain consistent RO blending at the SWTP. Flow signals from the SWTP RO system will be used to modulate the speed of the operating pumps using the motor VFDs.

Marco Island MF Project Backwash Recovery Basin Modifications MARCO MF PROJECT BACKWASH REPORT 12-22-10.DOCX 1 TECHNICAL MEMORANDUM Marco Island MF Project Backwash Recovery Basin Modifications PREPARED FOR: Marco Island Utilities PREPARED BY: CH2M HILL DATE: December 2010 Introduction The Marco Island North Water Treatment Plant (NWTP) currently uses granular media and Zenon filters that intermittently backwash to remove solids from the filters. Approximately 3-5 percent of the total feed flow to the NWTP is used for backwash. To minimize waste, this water is collected in a backwash recovery basin that equalizes the flow before it is pumped back to the inlet of the lime softening reactor. The new membrane filtration (MF) process operates similarly to the existing filters. Approximately 3-5 percent of backwash will be generated that needs to be equalized and recycled to the inlet of the lime reactor. However, the membrane filters are more efficient than the existing filters at removing solids. To avoid concentrating ultra-fine solids in the NWTP previously not removed by the filters and that may not be removed by the lime reactor, the exiting backwash recovery basin must not only equalize flow, but also provide additional solids removal and the ability to occasionally blow down accumulated solids. This section describes the existing backwash recovery basins, testing conducted to determine the needed treatment of the MF backwash waste, and the proposed modifications to the existing basins. Existing Backwash Recovery Basins The Marco NWTP currently has a backwash recovery basin that equalizes backwash flow before pumping to the head of the lime reactor. Exhibit 1 shows a schematic of the existing concrete backwash recovery basin. The basin currently has a single backwash equalization cell, an existing lime sludge holding cell, a thickener overflow cell, and an emergency overflow cell. All backwash enters and exits the backwash equalization cell on a normal basis. In the event of a high level in the equalization cell, water will overflow into the emergency overflow cell where another pump will recycle water to the inlet of the lime reactor. The thickener overflow and lime sludge holding cells operate independently of the backwash system. MARCO ISLAND MF PROJECT BACKWASH RECOVERY BASIN MODIFICATIONS MARCO MF PROJECT BACKWASH REPORT 12-22-10.DOCX 2 EXHIBIT 1 Existing Backwash Recovery Basin Marco Island NWTP Membrane Filtration Improvements Project Engineering Report MF Backwash Treatment Requirements The solids suspended in the MF backwash water require adequate time in an undisturbed settling zone to reduce turbidity before recycle to the head of the lime reactor. The single open cell currently used for backwash equalization and pumping will not work for this purpose because the inlet flow mixes the solids in the basin and the backwash recycle pump from the lowest point of the basin. To help evaluate the design criteria for solids settling and propose modifications to the existing backwash pond, a settling rate test was performed at the plant site using a 2” Pall MF module. The Pall MF module helped mimic the actual full scale performance of MF filtration and generation of backwash waste. Sufficient backwash volume was collected by running the Pall module with lime softened feed water. The backwash was allowed to settle in a jar for three hours. The turbidity of the top portion of the jar was recorded every 30 minutes. The settling test results shown in Exhibit 2 demonstrate that most of the solids settling occur within the first 60-120 minutes as the turbidity drops from 8.3 NTU down to between 1.2 and 1.6 NTU. After this time, there is little improvement in the turbidity. Therefore the backwash basin must provide at least 60 minutes of undistributed settling time and ideally more than 120 minutes.

The existing equalization cell will be converted into separate surge and settling zones, while the emergency overflow cell will be converted into a pumping zone. MARCO ISLAND MF PROJECT BACKWASH RECOVERY BASIN MODIFICATIONS MARCO MF PROJECT BACKWASH REPORT 12-22-10.DOCX 4 EXHIBIT 3 Backwash Basin Modifications Marco Island NWTP Membrane Filtration Improvements Project Engineering Report Key modifications to the backwash pond Reinforced concrete wall The reinforced concrete wall will divide the existing equalization cell into a surge zone and a slow settling zone. A 4-ft gap between the zones will allow the backwash water to flow from the surge zone into the settling zone. The wall is positioned to provide adequate volume in the surge zone to equalize backwash flows while separating surge mixing from the settling zone. The wall is also positioned to provide linear plug flow and adequate settling time in the settling zone without the need for settling plates. Existing vertical turbine pumps The existing backwash recycle vertical turbine pumps, which are sized for the higher current media filter backwash flows, will be used to purge solids from the surge and settling zones as needed. The discharge piping of these pumps will be connected to the existing RWPF off-spec water pond to provide a necessary air gap to avoid cross-connection. From the off-spec ponds, the waste backwash water will be pumped to the head of the RWPF for treatment. Rectangular settling zone overflow weir The rectangular weir will be cut into the existing wall and separate the settling zone from the pumping zone. The weir will help maintain a consistent depth and uniform plug flow in the settling zone to minimize short-circuiting and improve settling.

All necessary instrumentation will be provided to allow effective monitoring and control of the treatment process. Refer to the provided P&IDs and Block Diagrams for additional details. Process Instrumentation and Control System (PICS) The process instrumentation and control system (PICS) will expand on the existing control system at the Marco Island North Water Treatment Plant (NWTP) and include a new plant PLC, new Membrane Filtration Package system PLC and new Remote I/O (RIO) located at the new Chemical Storage area. The existing Wonderware SCADA system will be expanded to add screens for new processes added as a part of this project including screens for the Membrane Filtration system. Local manual controls at motor controllers and valve operators will provide a means of locally controlling and overriding PLC control. In general, instruments will locally indicate process measurements. The main portion of the NWTP upgrades and control system will be a packaged Membrane Filtration System. The Membrane Filtration package system will be controlled by an Allen- Bradley ControlLogix PLC and will communicate with the NWTP SCADA system via Ethernet/IP communications. Any required communications between the Membrane Filtration PLC and the Plant PLC system will be via hardwired I/O interfaces to minimize communications errors. Additionally, existing fiber optic Ethernet connections currently terminated in the Sand Filter Electrical/Control Room and to the North and South Construction trailers will be re- routed and terminated to the existing WTP Operations Building. Additional telephone and CATV interfaces will also be re-routed and terminated in the WTP Operations Building as required. The PICS design will not include any type of network security. It is assumed the Owner will work with their IT consultant and secure their network according to their standards. Any additional network security appliances will be provided by the Owner. It is noted that MARCO ISLAND MF IMPROVEMENTS PROJECT ELECTRICAL AND I&C DESIGN MARCO MF PROJECT ELECTRICAL-I&C REPORT 12-22-10.DOCX 2 the Membrane Filtration system requires remote network access for troubleshooting and maintenance requiring a direct connection to the Internet which could lead to potential vulnerabilities, however, mitigating these vulnerabilities is not a part of this project and will need to be addressed by the Owner’s IT consultant. The PICS will not include any type of building security, access controls, or CCTV systems. Any other building management and alarm systems will be provided as a part of the Membrane Filtration building design. Process Control The following systems will be evaluated during design development to determine if SCADA HMI screens exist and provide adequate functionality for plant operators:  Marco Lakes raw water pumps: Provide On/Off, Speed, and Flow Setpoint functionality from SCADA HMI. Requires an Ethernet connection between the WTP and WWTP control systems. Ethernet connection is shown to be provided as part of the Marco Island RWPF Phase III design and the existence of this connection will need to be confirmed during design.  Existing Lime Reactor System: Automate influent valve and add Lime reactor drive and rake control to the SCADA HMI.  Membrane Filtration Package System: Duplicate package system control screens on the SCADA HMI System.  New Chemical Systems (Alum, Lime, Carbon Dioxide, Sodium Hypochlorite, Phosphoric Acid, and Ammonia): Provide remote manual control of all chemical systems from the SCADA HMI. Determine which chemical systems require automatic PID, Trim, or flow pacing control during design development.  NWTP High Service Pumps: Provide SCADA HMI screens for monitoring and control.  SWTP High Service Pumps: Provide SCADA HMI screens for monitoring and control. No other systems at the NWTP or SWTP are planned to be added or modified to the Owner’s SCADA HMI or PLC system. Process systems added to SCADA HMI not currently connected to the PLC system will have available equipment I/O connected to the new plant PLC in the Membrane Filtration building or to the new Remote I/O located at the Chemical Storage facilitiy to allow incorporation onto the SCADA HMI screens. PLC and SCADA Systems Koyo DirectLogic PLCs will be used for all PICS PLC and RIO applications. New systems will be controlled by a Koyo DirectLogic 405 PLC which will be located in the main control panel located in the Membrane Building Electrical Room. The PLC will interface with field devices and Package System controllers via hardwired I/O and control functions will be accessed from SCADA via Ethernet. The Owner’s existing Invensys Wonderware HMI software and the Owner’s existing HMI servers and workstations will be used for SCADA. The Owner’s SCADA system will be updated to incorporate new systems including additional reporting requirements for MARCO ISLAND MF IMPROVEMENTS PROJECT ELECTRICAL AND I&C DESIGN MARCO MF PROJECT ELECTRICAL-I&C REPORT 12-22-10.DOCX 3 systems added as a part of this project. The HMI software will be updated as required to support new systems and communications. The PLC for the packaged Membrane Filtration system will be an Allen-Bradley ControlLogix PLC which will be housed in the Membrane Filtration system Main Control Panel in the Membrane Building. The PLC will interface with field equipment via hardwired I/O and with Membrane trains via Ethernet/IP connected Pneumatics remote I/O units. Any communications required between the Plant PLC and the Membrane Filtration system PLC will be via hardwired I/O. In-Plant Communications Networks The primary network used for communications across the PLC/HMI networks will be 10/100/1000BASE-TX Ethernet over Category 6 copper Ethernet cables and Gigabit Ethernet over fiber optic cable. Loose buffer gel-free Multimode 62.5/125 micron fiber is currently being used and new fiber optic data links will use the same type of fiber. Sixnet industrial managed switches and media converters will be used to match the existing network components at the plant. Cable routing and outlet locations will be discussed further in the Electrical Section. The existing network is connected with main nodes in a star configuration to the existing switch in the NWTP Operations Building. New major links will be added using the same configuration. This configuration does not provide fault tolerant communications. If a link is disconnected or damaged, all data associated with that link will not be available on the network, but other links will still be available. New communications connections include a fiber optic Ethernet connection between the new fiber optic Ethernet switch located in the plant PLC enclosure and the existing gigabit switch in the NWTP Operations Building. Additional communications connections include connection to the Pall System switch, Pall System remote I/O units, and Remote I/O at the Chemical Storage facility. No other new communications are planned to be added. Existing fiber optic Ethernet connections currently terminated in the Sand Filter Electrical/Control Room will be evaluated and re-terminated to the WTP Operations Building if it is determined that they are still required for proper Plant communications. These connections include communications to the onsite Trailers, Lime System, and to the County WAN external to the plant. These connections need to be evaluated with the Owner and the Owner’s IT manager to determine requirements including construction scheduling, equipment preferences, and interface preferences. Existing plant Ethernet and Radio communications paths at the Plant will be utilized for all other plant communications, such as communications with equipment at the Marco Lakes location. The current NWTP control system network also has several connections to business, public, and city wide area networks (WAN). It is not currently known if these connections are through a local internet service provider (ISP) or are private City maintained communications service connections. Control Systems connected to Business networks and/or the Internet face an increased risk of being adversely affected by malicious software and of being penetrated by attackers. It is not currently known if the network, SCADA MARCO ISLAND MF IMPROVEMENTS PROJECT ELECTRICAL AND I&C DESIGN MARCO MF PROJECT ELECTRICAL-I&C REPORT 12-22-10.DOCX 4 servers, or PLCs at the NWTP have security measures in place and is network security measures are not being investigated as a part of this project. However unless the City is confident that current network security provisions are adequate, evaluation of the entire City SCADA network is recommended to determine if additional security improvements are required such as network segmentation using Virtual Local Area Networks (VLANs) or addition of Demilitarized Zones (DMZs). For example, current standards such as the latest draft standard of NIST SP 800-82, Guide to Industrial Control Systems Security, also recommends Firewall blocking of email (SMTP) and internet (HTTP) protocols on process control networks. However a detailed network risk assessment would be required to determine security measures applicable to the City of Marco Island Water Treatment System SCADA network. Raceways will be provided for Telephone connections, if required. Telephone circuits will be designated and provided by the Owner. Field Networks Field networks are device level networks that connect multiple signals from devices, such as variable speed drives and electric motor operators, to the PLC via a serial data communications link instead of hardwired I/O. No Field networks are being provided as a part of this project. Provisions For Future Expansion Two membrane trains and related process equipment are planned to be provided in the future for expansion of the NWTP membrane filtration system. PICS and Package Control systems will be provided with sufficient installed I/O and spare space to allow incorporation of these items into the systems provided as a part of this project. Software will be designed to allow incorporation of these items into the PLC and HMI programs without major re-programming. The PICS PLC system will also be provided with a minimum of 15% spare installed I/O in addition to the I/O reserved for known future equipment.

Control Modes & Levels of Automation General philosophy The PICS will provide automatic and manual control of equipment. Control Modes & Selection Both LOCAL, primarily manual, and REMOTE controls will be provided as follows. Local Control All equipment will have manual local control devices located at the motor controller location for emergency operation, maintenance, and testing. In LOCAL operation, PLC control will be bypassed. Controllers will need to be set for REMOTE operation to allow PLC control. Local controls will be independent of the PLC except for hardwired interlocks for personnel safety and equipment protection such as motor overloads, emergency stop, low/high liquid level protection, etc. PLC Control PLC control is accomplished from any PC workstation having the appropriate HMI software using HMI graphic displays. This is the control level for normal system operation. Any PC workstation on the PLC/HMI network can be used for process monitoring and control of any process in the facility. Any equipment that is controlled automatically by the PLC system will also be provided with a PLC manual control mode. This will allow individual equipment to be manually controlled from PC workstations. The membrane filtration package system may not have the same manual control mode. The Owner’s existing SCADA workstations and servers will be used for this project. No new workstations, servers, or standard PC software will be provided as a part of this project. Automatic and manual control logic will be implemented in the PLCs. Control logic will not be performed in PC workstations. The Owner’s existing control for PC workstation access and applications software user levels will be followed for all new HMI programming. Tag Numbering System Equipment, Control Valves, and Instrument Numbering System A standard numbering scheme will be used for this project, except for Package Control System equipment, that will include equipment, instrumentation, and control loops. The tag number consists of, device identification letters, followed by a sequential “loop” number, a unit number, and an optional letter suffix. This numbering scheme is described below.

MARCO ISLAND MF IMPROVEMENTS PROJECT ELECTRICAL AND I&C DESIGN MARCO MF PROJECT ELECTRICAL-I&C REPORT 12-22-10.DOCX 9 Electrical Systems Description of Power Distribution The North Water Treatment Plant Membrane Filtration Facility one line drawings show the basic power distribution scheme for the facility. Below is a description of the major electrical distribution system features:  The power feeds to the Existing Zenon System #1 and Existing MCC-5 located in the Sand Filter Electrical Room will be demolished with conductors removed and conduit abandoned in place. Feeder breakers for these equipment will be either reused or marked as spare.  Power will be fed from the existing Low Voltage Switchgear LVSG-2 located in the Operations Building Electrical Room. The ratings and trip settings of the Existing breakers in the switchgear will be evaluated to meet the needs of the new electrical loads in the Membrane Filtration Facility.  MCCs will be rated for 800 Amps, 480Vac, 65kAIC to match existing feeder breakers in LVSG-2 and Interrupt Current capacity selected based on the Power System Study performed by GE. Fault currents will be increased as appropriate based on calculations performed during design development. The number of MCCs required will be determined during design development to accommodate all electrical loads, including known future loads, and providing some spare capacity for future modifications.  A new 480Vac panelboard, transformer, and 208Y/120Vac panelboard will be located at the new Chemical Storage facility for local power distribution. The 480Vac panelboard will be fed from one of the new MCCs in the Membrane Filtration Building.  The existing MCC-6 building will be demolished and circuits powered from MCC-6 will be re-fed from new Chemical Storage Area panelboards.  Equipment currently powered from existing MCC-5 that is still required to be in operation will be re-located into the new MCCs located in the Membrane Filtration Building.  Equipment performing similar functions will be fed from separate MCCs to allow continued operation of similar equipment during MCC maintenance or failure such that taking a single MCC out of service will not disable processes that have lead/lag or duty/standby type operation. Equipment that is part of the same process train will be located in the same MCC where feasible.  All 480V distribution for the Membrane Filtration Facility will be provided from the new MCCs. Power feeds to other new equipment not located at the Membrane Filtration Facility will be obtained from the nearest suitable electrical power source.  Motor Starters, AFDs, and Equipment requiring over 100Amp, 480Vac breaker feeds will be fed from the MCCs. All other equipment will fed from panelboards.

CH2M and WSA are familiar with the NCRWTP system and will incorporate our existing understanding of data gaps into the planned scope and analysis.  Use of innovative, unproven technologies without testing, and if not successful, requiring equipment modifications after startup: mitigate by doing due diligence and perform additional testing if the proposed technology is not proven yet on this type of water.  Future raw water quality variations differ from the projections, either in TDS or other water quality constituents, requiring equipment or operational modifications after startup: mitigate by doing detailed projections, verify with other utilities who have experienced variable TDS and provide flexibility in design. Use recent CH2M experience and lessons learned in variable TDS evaluation and design to anticipate and account for likely issues.  Finished water quality is different from projections due to different raw water quality or use of different types of membranes/treatment regime requiring additional post conditioning chemicals and corrosion control testing: mitigate by conducting post‐treatment evaluation early and provide flexibility in post‐ treatment process.  Existing well/pipeline/fittings and process equipment are over 15 years old, and may fail due to condition during the startup and/or operation with the higher salinity water: mitigate by conducting a condition assessment, review material compatibility with higher TDS water, and include upgrades as part of this project.  Combined concentrate water chemistry changes as part of this project leading to precipitation of scales in pipe or injection well: mitigate by performing desktop water chemistry modeling and bench scale testing using CH2M’s in‐house Applied Sciences Laboratory to predict scale formation in concentrate and develop III‐3 methods to mitigate. Use CH2M experience at several facilities where potentially incompatible waste waters have been combined before deep well injection.  Client is not able to make a selection of the preferred alternative delaying the project: mitigate by involving the client in every step/decision during the project. Use a clearly defined, documented and defensible decision making process as successfully completed on several project using CH2M decision making tools.  Cost of implementation of preferred alternative is above the budget requiring rework to get within budget costing time and money: mitigate by developing detailed and reliable capital and operating cost opinions using CH2M’s CPES™ cost model early in the alternatives evaluation and conceptual design phases and developing a financing and phasing plan.  Conversion of existing BWRO trains to variable TDS RO trains requires multiple and extensive plant shutdowns impairing ability to make water: mitigate by providing constructability reviews and by working together with the County to develop phased implementation plan, with potential temporary utilities/facilities.  The TDS in the affected wells declines over time and matches the other wells resulting in an unutilized asset for variable TDS treatment: mitigate by providing a flexible treatment solutions capable of treating low TDS water even if less efficient. Identify process that provide multiple benefits like energy reduction or concentrate minimization to offset potential inefficiencies. Design flexibility into the overall treatment process by selecting components that can be used for multiple scenarios if anticipated early.

III‐9 MARINA EAST VARIABLE SALINITY DESALINATION PLANT, SINGAPORE Client Name: Public Utilities Board, Singapore Size: 36 mgd Project Value: Confidential Project Duration: 2014‐2015 Key Highlights/Relevant Features:  VSP technology offers the potential to treat brackish water and seawater cost‐ effectively in the same plant  Comprehensive cost estimating  Architecture and landscaping designed both to integrate with the surroundings and offer a point of interest to the general public  Innovative layout occupying 3 levels  Environmental impact assessment (EIA) study for the 30MIGD desalination plant Singapore and its neighbors, most relevantly Malaysia, have recently experienced drought and this has resulted in challenges for the Public Utilities Board (PUB) total water management approach. Availability of imported water is becoming less certain than in the past due to climate change and the sustainability of this source is uncertain. PUB continues to investigate other sources of supply and recently engaged CH2M to undertake an investigation and conceptual design of the 36 mgd Marina East Variable Salinity Plant (MEVSP). This high profile desalination plant is located in a prominent location near the CBD of Singapore. The constrained 3 hectare site within public parkland necessitated an innovative layout occupying 3 levels and incorporating DAF and UF pre‐ treatment and two‐pass Reverse Osmosis. Seawater and brackish water will be abstracted through dedicated intakes drawing from the Singapore Straits and the Marina Reservoir, respectively. This will allow PUB to choose on a daily basis between the treatment of seawater or brackish water, which requires a much lower specific energy consumption and results in a significantly lower cost of treatment. The treatment process for MEVSP has been developed to meet World Health Organization (WHO) and PUB drinking water quality guidelines based on an analysis of water quality data from both the Marina Reservoir (post‐barrage construction) and the Singapore Straits. Due to inherently different plant losses when operating on Marina Reservoir water compared to seawater, the MEVSP will be capable of converting a higher percentage of Marina Reservoir water into potable water than seawater. As a result, the plant output will be higher when treating Marina Reservoir water than seawater. CH2M Role/Responsibilities: CH2M is providing the full spectrum of conceptual design services including;  Boundary Limits Workshops  Environmental Impact Assessment Studies  Concept Process Design Development  First Cut Infrastructure Development  Process Design Development  Equipment Sizing  Electrical System Design  Plant Layout Option Development  Preliminary Cost Estimation & Constructability Assessment  Option Screening  Design Refinement  Cost Estimation  Design Report III‐10 GREEN MEADOWS WTP EXPANSION, LEE COUNTY, FL Client Name: Lee County Utilities Size: 16 MGD Project Value: $70 million USD Project Duration: 2012‐2016 Key Highlights/Relevant Features:  Feasibility and pilot studies identified the best value option using a benefit cost analysis and CH2M tools ‐ provided Lee County exceptional value.  The RO building incorporates space‐saving concepts like a center‐trench design and train‐specific roll‐up doors and includes operator facilities.  Evaluation identified the benefits of alternative ion exchange regeneration using RO concentrate and seawater wells.  The design includes concentrate and regenerant disposal by two injections wells. The existing Lee County Utilities Green Meadows lime softening facility treats a blend of fresh surficial and intermediate aquifer groundwater sources. The existing facility was nearing the end of its useful life and needed to be replaced to maintain reliability and to continue to meet regulations. To limit the demand on fresh water sources, the larger new facility uses a brackish groundwater well source in addition to the existing wells for expansion. The new 16‐mgd facility uses reverse osmosis for desalinating brackish well water in parallel with cation and anion exchange used to remove iron, hardness and organics from a surficial aquifer fresh water source. A new seawater well provides an alternative source of brine for cation exchange resin regeneration to reduce operational costs. The estimated $35M facility is part of a $70M project that includes new wells, wellfield pipeline/roadway, and concentrate disposal wells. CH2M Role/Responsibilities: CH2M conducted a process evaluation and subsequent 1‐year pilot study to determine the most economical and efficient treatment system to make use of all three water sources. The treatment process’s identified were cation and anion ion exchange as the most cost effective and reliable process to treat a blend of the existing fresh water sources and a new RO system that will treat the brackish source before blending with the treated freshwater sources. The studies identified and subsequently verified through pilot testing that RO concentrate and/or seawater wells could effectively regenerate the cation exchange resin to significantly reduce operating cost of the new facility. CH2M conducted a desktop analysis of blending three different groundwater supplies using our Source™ water quality and treatment modeling tool to quickly identify impacts of blending on treatment and optimize options for further proof pilot testing to confirm and develop design criteria. Our CPES™ tool was used to develop costs for several different treatment variations and capacities to help the County define the best value option for the facility. Our Bridge™ design tool allowed the project team to quickly and cost effectively complete the design to meet a limited design budget and project schedule. CH2M used its Preview™ tool into provide 3‐D representations early in the design process to help freeze design decisions early. Dynamic simulation using Replica™ was also conducted during the project to optimize energy efficiency and hydraulics. III‐11 BONITA SPRINGS RO WTP, BONITA SPRINGS, FL Client Name: Bonita Springs Utilities Size: 6 MGD expandable to 12 MGD Desalter Project Value: 40.8 Million USD Project Duration: 1993‐2013 Key Highlights/Relevant Features:  CH2M successfully managed more than 22 subconsultants and delivered the RO WTP on time and within budget  Saved BSU $500,000 from direct contracting for equipment features, eliminated 3 weeks from the original schedule, and reduced construction costs by $50,000 by developing a unique installation method for the RO feed pump cans  20‐year relationship, providing water and wastewater treatment, regional irrigation planning, and general engineering services to BSU Located in a popular resort and tourism area, the Bonita Springs Utilities (BSU) service area is subject to peak seasonal water demands due to visiting tourists and part‐time residents. CH2M Role/Responsibilities: CH2M began assisting BSU in 1993 with a wide range of utility engineering, construction, and specialty evaluation services for water, wastewater, and reclaimed water systems. As part of this, CH2M prepared a water quality study for the potable water system. The study reviewed short‐ and long‐ term options for expanding the existing potable water system to meet emerging water quality regulations. In 1997, we implemented a 3‐mgd expansion to the existing potable water lime softening WTP using the traditional design‐bid‐build delivery process. In 2000, to respond to rapid continued growth in the area, CH2M completed a second expansion to this lime softening plant, increasing operating capacity to 13 mgd; this second expansion also used the design‐build delivery process. In 2002, CH2M commenced a design‐build of a new 6‐mgd (expandable to 12 mgd) RO water treatment facility constructed on the existing lime softening facility site. This new RO WTP project included installation of three cartridge filters; four RO feed pumps; four RO membranes trains; chemical systems; degasifier and odor scrubber system; 2‐million‐gallon ground storage tank; five brackish water production wells with pumps and wellhead; three new high‐service pumps; new finished water transmission main; raw water meter and new yard piping; plant generator; seven wellhead generator; electrical upgrades; instrumentation and controls software upgrades; and lime softening water plant slaker. The demineralization facility was constructed to treat the brackish water and the treated water was blended with the existing lime softened water prior to storage and distribution. The RO WTP was designed conservatively, so that its processes and equipment can accommodate potential degradation of source water quality over the next 20 years. The project involved a new 4,160‐volt electrical service and ductbank loop to existing and new site facilities and a new sodium hypochlorite generation system for both the lime softening facility and new RO facility. In 2012, CH2M completed an upgrades study, design and construction project that optimized membrane replacement, new energy recovery devices (ERDs), potential train expansion and overall wellfield and RO train control that saved the utility more than $150,000 in annual power costs. The project featured a Replica model of the complete RO and wellfield system that was used to find operational strategies that could save the utility additional power cost. “CH2M is one of the few consultants I can count on to act as an extension of my staff. When I need help and need it now, I know that CH2M will deliver.” —Fred Partin, Executive Director, BSU III‐12 NORTHWEST RIVER WTP, CHESAPEAKE, VA Client Name: City of Chesapeake Public Utilities Size: 12 MGD Project Value: $56.9 million Project Duration: 1993‐1999 Key Highlights/Relevant Features:  This project won the top award, Engineering Excellence Award, in the Water and Wastewater category from the Consulting Engineers Council of Virginia.  The first completed operating ASR system in the state of Virginia For several years the City of Chesapeake considered alternatives for upgrading the Northwest River WTP. The raw water is highly colored river water with characteristics that include high concentrations of total organic carbon and manganese, low alkalinity, and low pH. Saltwater intrusion into the river during low flow, summer periods and a need to comply with future regulations restricting disinfection by‐products (DBPs) were the two main drivers behind the upgrade. CH2M Role/Responsibilities: The City selected CH2M to design upgrades to the existing conventional treatment processes – rapid mix, flocculation, sedimentation, and high‐ rate filtration – and to design a new membrane treatment facility. The new membrane treatment facility is designed to treat conventionally treated surface water or brackish water from deep wells. The surface water and groundwater reverse osmosis (RO) systems have capacities of 8 mgd and 4 mgd, respectively. Previously, CH2M conducted a membrane pilot test program to help determine the most feasible approach to removing DBP precursors and protect against saltwater intrusion. The pilot programs confirmed the feasibility of upgrading the Northwest River plant. The proposed design for the upgrade included separate facilities for membrane treatment of filtered water from the river and of brackish water from deep wells. Pilot testing was also used to confirm suitability of the combined RO concentrate (from the surface and brackish water RO trains) for discharge to the south branch of the Elizabeth River. This required concurrent operation of two separate RO pilot units to produce representative concentrate from which toxicity and trace metal analyses could be performed. The design, which resulted in one of the most sophisticated WTPs in the U.S., includes conventional and membrane processes that allow maximum flexibility for treating the variable water sources. Four process trains fitted with low fouling, RO membranes effectively handle saltwater intrusion into the river. Two separate trains using high rejection RO membranes treat the higher‐salinity brackish groundwater from the production wells. Under the worst‐case operating scenario, all membrane trains operate on flow from the river, and all wells are in service. Under typical (non‐brackish) conditions, only one or two membrane trains operate, saving energy. “The 10‐mgd upgrade of our surface water conventional treatment plant to surface and groundwater RO was a huge undertaking for the City of Chesapeake... The design by CH2M was extraordinarily complex, requiring not only a sound design but the need for an integrated upgrade that would allow an existing plant to remain in continuous operation during construction. Virtually every design and construction challenge was overcome in a way that best combined the input of the design engineer, contractor, and the City...” —A. Craig Maples, Water Production Superintendent, City of Chesapeake, Water Production Division III‐13 RO WATER TREATMENT PLANT, CITY OF FT MYERS, FL The City of Fort Myers WTP was designed and built (by others) in the early 1990s as a membrane softening facility treating surficial groundwater. The facility was designed for a capacity of 12 mgd with an ultimate future expansion to 20 mgd. The facility was converted by others to a brackish water RO facility in 2002 because of feed water quality problems. The conversion reduced WTP capacity to 8 mgd due to feed water pumping and post‐treatment limitations. As the designer and general contractor, CH2M provided pre‐design, final design, procurement, permitting, construction management, and startup services, as well as services during construction. This project expanded the raw water supply, expanded the RO WTP capacity from 8 to 13.3 mgd, as well as resolved existing post‐treatment water quality issues. Specific treatment components included a transmission main; two degasifers; membrane feed pumps; RO equipment; production wells; raw water sand strainers; upgraded plant control; and upgraded plant electrical. CH2M HILL subsequently provided design‐build services to design and for this design‐build project, The project was delivered under budget and within schedule in spite of delays as a result of four hurricanes. MEMBRANE SOFTENING WTP, AVE MARIA UTILITY COMPANY Located on 5,000 acres of former farmland, Ave Maria is a new city development consisting of a university and surrounding community of residential units, retail stores, medical facilities, hotels, public schools, and parks. CH2M HILL began work on this design‐build‐operate project in 2005 and was responsible for design, permitting, construction, and operation of the located water facility, including a natural treatment wetlands treatment system being developed on the greenfield site. The WTP design is a 1.67‐ mgd membrane softening facility. Concentrate from the WTP is sent to the 1.25‐mgd WRF for disposal. Three water supply wells provide raw water for the system. CH2M HILL met the overall development schedule by preparing preliminary engineering reports that met FDEP requirements for permitting early in the development of the construction documents. While FDEP reviewed the permit applications, construction document preparation continued, saving time in the schedule. Early discussions and presentations to the permitting agencies helped to streamline the process. Procurement of equipment was also started early in the schedule, prior to completion of the final construction documents so that delivery of key equipment wouldn‘t slow construction. Completed in 2006, CH2M HILL OMI is contracted to operate the newly constructed facilities for up to 20 years based on four recurring 5‐year contracts. “We are extremely pleased with our relationship with CH2M HILL. They delivered on all facets of the design, construction, and operation of our facilities and within the timeframe and budget established. Their professionalism, technical expertise, and dependability have earned them a place on our team – now and in the future.” David B. Genson, PE, Director, Ave Maria Utility Company For the RO WTP project, we saved the City of Fort Myers more than $1,290,000 through diligence of scheduling, well design changes, and controlling labor costs during construction. This Ave Maria project was the winner of the 2007 Design‐Build Institute of America Merit Award for water/ wastewater projects over $15 million. III‐14 FORWARD OSMOSIS / RO HYBRID FEASIBILITY STUDY, TEXAS WATER DEVELOPMENT BOARD, TX CH2M HILL worked with the TWDB to evaluate a hybrid forward osmosis/reverse osmosis (FO‐RO) process to recover water from high salinity water for beneficial use. The study sought to examine the mechanics of forward and reverse osmosis water treatment; assess the feasibility of using high salinity streams to extract water out of water streams; and, determine characteristics required for cost‐effective application of this hybrid process. Bench‐scale pilot testing was completed to evaluate feasibility while cost modeling was also conducted to determine viability compared to other treatment options. Assuming that membranes can be commercially produced at a reasonable price point, it is anticipated that use of FO‐RO may be viable at some point in the future. This study provided several recommendations for continuing the development of the hybrid FO‐RO process. CALIFORNIA SEAWATER DESALINATION DEMONSTRATION FACILITY CITY OF LONG BEACH, CA CH2M HILL provided senior level process consulting in conjunction with construction and operation of the Seawater Desalination Prototype Demonstration Facility. The Facility utilizes a unique two pass nanofiltration (NF) system, developed and patented by the Long Beach Water Department (LBWD), for the purpose of seawater desalination. CH2M HILL served as a technical advisor to LBWD for both low pressure MF and high pressure RO membrane process engineering support during construction of the Facility. Once operational, CH2M HILL participated in a study entitled Ultraviolet (UV) Light and Chlorine Dioxide Seawater Pretreatment Systems for Biogrowth Control and Pathogen Inactivation, funded in part by Proposition 50 grant from the California Department of Water Resources. The study investigated, on both a bench‐ and demonstration‐scale, the suitability of UV and chlorine dioxide for controlling biofouling of nanofiltration and reverse osmosis systems used to desalinate seawater and to achieve virus inactivation requirements as mandated by the CA Department of Health Services. CH2M HILL prepared a research work plan that served as the basis for testing conducted under the study. A draft research plan was first developed with the input of a panel of outside technical advisory panel and LBWD in a workshop and finalized following subsequent review by LBWD and the panel. CH2M HILL also provided oversight during the testing, in part conducted by UCLA, and reviewed test data and reports. OLGA VARIABLE SALINITY SURFACE WTP EXPANSION EVALUATION, LEE COUNTY, FL CH2M HILL conducted a study and preliminary design charged with finding the optimum source water and treatment expansion option for an aging conventional surface water treatment. The study examined current and anticipated water treatment and water supply regulations, raw water availability and storage options, treatment options, and operation and maintenance costs. A benefit‐cost analysis helped identify the optimum solutions that were then benched‐tested on the project site. Bench testing of new membrane filtration and reverse osmosis processes was conducted on existing and potential new raw water sources to examine treatability and costs effectiveness on multiple process options. WEST PILBARA SWRO FEASIBILITY SITING AND COSTING STUDY, WATER CORPORATION OF WESTERN AUSTRALIA CH2M HILL conducted a feasibility study and concept design for the construction of a desalination plant as part of the West Pilbara Water Supply Scheme. Using our experience in cutting edge technologies, several options and processes were evaluated to produce an innovative solution. III‐15 The existing seawater in the proposed area was originally discounted due to the reportedly poor and variable water quality near the existing intake facility. CH2M HILL reviewed the operation of this intake and found that an improvement in water quality could be achieved through upgraded works and that full replacement of the intake facility would not be required for several years. CH2M HILL also looked at the treatment process selection as part of this study. The pretreatment and desalination technologies were chosen based on an impartial analysis of monetary and non‐monetary criteria. A decision making framework was created which ranked and weighted all of the "success criteria" which were important to the Water Corporation. This was combined with cost estimates to determine the best outcome from a cost ‐ benefit perspective. CH2MHILL created a generic design, complete with layout drawings and equipment sizing based on its global design experience. This information will guide the Water Corporation in their land acquisition negotiations EVALUATION AND OPTIMIZATION OF EMERGING AND EXISTING ENERGY RECOVERY DEVICES FOR DESALINATION AND WASTEWATER MEMBRANE TREATMENT PLANTS, WATEREUSE FOUNDATION CH2M HILL developed a computer based tool to evaluate current and emerging energy recovery devices based on their performance, applicability and life cycle costs. The model covers all known and applicable commercially available energy recovery device and all associated systems that impact it. The tool allows the user to develop an optimum RO system design based on feed water quality and desired product water quality. SEAWATER AND BRACKISH WATER DESALINATION SITING, FEASIBILITY AND COSTING STUDY, NEW YORK DEPARTMENT OF ENVIRONMENTAL PROTECTION, NY CH2M conducted a feasibility and costing study for 200 mgd BWRO and 50 mgd SWRO facilities for the City of New York. The project included the site planning, conceptual design, and cost development of a 200 mgd brackish water RO facilities treating a tidally influenced river water source and a 50 mgd seawater facility with dual pressure filter pretreatment system and post treatment facilities treating an open intake seawater source. The study examined site constraints, raw water quality, treatment options, residuals disposal, capital costs, and operation and maintenance costs. CH2M as the technical member of the team that studied alternatives for development of up to 400 mgd of emergency supply, including brackish and seawater desalination, as part of New York City’s long‐term water supply strategy. CH2M was responsible for an in‐depth evaluation of brackish and seawater desalination at various sites along the Hudson River and in New York Harbor, including the development of cost models for these processes. The study included an analysis of intakes, pretreatment, membrane treatment, energy recovery, post‐treatment, and residual management technologies. Cost models were developed for the “highest cost and largest footprint” design and the “lowest cost and smallest footprint” design at each location. A total of 14 cost scenarios were developed for four sites, capacity options, and high and low cost alternatives. CH2M then performed a statistical analysis of raw water quality, current and future water quality regulations, recommendations for finished water quality parameters, and detailed analysis of treatment alternatives for intakes, pretreatment, desalination technologies, post‐treatment alternatives, and brine return. Alternatives were reviewed on a site‐by‐site basis to determine the most feasible processes for each potential site. The benefits and costs for each alternative were evaluated and facility plans were developed for three desalination facilities (50 mgd, 200 mgd, and 400 mgd). CH2M helped the Water Corporation prove the feasibility of Seawater Reverse Osmosis as a sustainable option. III‐16 Other CH2M Desalination Project Examples SEAWATER DESALINATION SITING, FEASIBILITY AND PILOT STUDY HONG KONG WATER SUPPLIES DEPARTMENT, HONG KONG CH2M designed and managed a 30‐month study to establish technical, engineering, environmental, and budgetary information required to enable the Hong Kong Water Supplies Department to reach an informed decision on how best to implement SWRO, in preparation for their 140 MLD facility. The scope of the study included identifying prospective plant sites and conducting pilot trials to define RO design requirements, identification of the most effective pre and post treatment processes, and development of capital and operating cost estimates for one or more full scale facilities. The pilot program was comprehensive and involved testing for a continuous 12‐month period at two separate locations (24 months total), selected to represent the two types of marine water quality characteristics. Three types of pretreatment were evaluated: granular media filtration, pressurized ultrafiltration and submerged ultrafiltration. Three types of RO membranes were also evaluated: Dow FilmTec, Hydranautics, and Toray. Post‐ treatment blending with existing water supply was also evaluated to ensure smooth introduction of desalinated water into the current supply. A complete capital and operating cost evaluation was included in the project. SEAWATER DESALINATION FEASIBILITY STUDY City of Port St. Lucie, Port St. Lucie, FL CH2M conducted a planning study that investigated water supply alternatives to meet future water supply demands for the City of Port St. Lucie including reverse osmosis desalination of seawater with an anticipated capacity of up to 50 mgd. The scope of work included capital and operation and maintenance cost estimates for the selected primary supply and treatment alternatives. Seawater Desalination Plant Melbourne Water Corporation, Australia CH2M HILL provided Melbourne Water Corporation (MWC) with expert advice relative to their seawater desalination plant. The planning, permitting, design and construction of the 120 mgd desalination facility, the world’s largest RO plant at commissioning, included cost, environmental, and public acceptance issues that were integral to the project’s success. We have worked closely with MWC and their consultants to resolve technical issues regarding finished water quality, cost implications of low total dissolved solids (TDS) requirements, post‐ treatment alternatives for blending purposes, and public acceptance. Of particular sensitivity is TDS levels, boron and bromide concentrations in the finished water while maintaining overall low corrosivity relative to the long transmission lines. Southern Seas Seawater Desalination Plant Water Corporation of Western Australia The Southern Seas Seawater Desalination Plant is the second large‐scale seawater desalination plant in Perth at commissioning utilizes renewable energy to provide all the power for this 38 mgd facility. CH2M HILL, the owner’s engineer, worked hand‐in‐hand with the utility to develop specifications, evaluate proposers, and then guide the two shortlisted proposers through the full proposal process prior to award. In our role as owner’s engineer, we have assisted Water Corporation to determine the ‘short list’ and to make recommendations on numerous significant technical issues, which impacted the final design of the facility. The white papers created include Advancements in SWRO; Post Treatment with Lime and Turbidity in Product Water; Oil and Grease Testing in Seawater for RO Membranes; and RO Concentrate for Granular Media Filter Backwash. Layyah, Khor Fakkan, and Kalba Seawater Reverse Osmosis (SWRO) Plants Sharjah Electricity and Water Authority, United Arab Emirates CH2M HILL served as the single source of responsibility for EPC services for turnkey delivery of three SWRO treatment plants with a total capacity of 16 mgd and expandable to 32 mgd. The Layyah Seawater RO plant is III‐17 located within the Arabian Gulf, which is known for seawater that is warm in temperature and high in salinity. To ensure adequate pre‐treatment, the process design includes 3‐millimeter (mm) screening, dilution/ attenuation, and two‐stage media filtration. Both Kalba and Khor Fakkan plants are located on the Indian Ocean coast of the United Arab Emirates. Pre‐treatment at Khor Fakkan includes passive 3 mm screening and two‐stage media filtration, while at Kalba pre‐treatment is achieved through UF membranes with upstream protection by passive screening and pre‐filtration screens. Onsite pilot testing was conducted to verify UF performance and design parameters. SWRO Plant Power Seraya, Singapore In late 2005, Power Seraya engaged CH2M HILL to conduct a feasibility study and functional design for a new SWRO desalination WTP at the Pulau Power Seraya Station. After the successful delivery of the feasibility study and functional design and positive experiences working with the CH2M HILL team, Power Seraya requested that we continue with the new SWRO desalination plant, utilizing a design‐build delivery model. The Power Seraya Seawater Desalination Plant project is the world’s first full‐scale desalination plant to use large‐ diameter SWRO technology. CH2M HILL designers took advantage of the existing infrastructure at the neighboring power station to maximize efficiency and cost savings while maintaining technical performance. The Power Seraya plant produces two qualities of water: high‐grade service water at a rate of 2.4 million gallons per day (mgd) and domestic drinking water at 0.26 mgd. SWRO Pilot Plant Marin Municipal Water District, California CH2M HILL, in partnership with Kennedy Jenks Engineers, served as the technical advisor for planning, design and operation of an 85,000 gpd seawater RO pilot plant for the Marin Municipal Water District, California. The pilot plant comprised two screening systems (wedge wire and compressed disc), three separate pretreatment trains two submerged hollow fiber membrane systems (MEMCOR CS MF and ZeeWeed 1000 UF) and conventional (coagulation/flocculation/sedimentation/granular media filtration) and two full‐recovery seawater RO trains, each containing ultra‐high rejection elements from three different suppliers. The purpose of the pilot study was several‐fold: (1) to assess and compare performance of two screening systems and three pretreatment systems (relative to downstream RO performance and fouling control), (2) demonstrate the ability of seawater RO to produce finished water complying with EPA drinking water standards and local requirements for un‐regulated trace contaminants, (3)characterize the RO concentrate relative to sewer discharge requirements and (4) prepare costs for full‐scale (~40 mgd) desalination plant. The pilot plant was also used to gauge public opinion on the taste of desalinated water through a public outreach event in which samples of desalinated water and the MMWD’s current drinking water supply were made available for tasting. In addition to that for the pilot plant, extensive source water sampling was conducted at three sites considered most suitable for full‐scale plant construction in order to understand differences and their impact on full‐scale plant design. Results of the study were used to assess feasibility, cost and public acceptance of SWRO desalination as a means of supplementing and ‘drought proofing’ Marin County’s water supply. Demonstration Project for Integrated Concentrated Photovoltaic‐SWRO System Confidential Client, Middle East CH2M HILL is under contract to assist in the development of a demonstration project that integrates a commercially‐available concentrated photovoltaic (CPV) system for power generation with a commercial SWRO desalination facility for drinking and industrial water production. The goal of the project is to demonstrate that a seawater desalination system can be powered by renewable energy using solar energy. The CPV system will have an output of 5‐10 megawatts while the SWRO system will be sized to produce approximately 5 mgd of desalinated water. Under our contract, we will develop a scoping document that defines the capacity of the CPV/SWRO system and the manner in which the two technologies will be integrated, prepare a conceptual‐level design and III‐18 associated order‐of‐magnitude cost for the facility, identify and define parameters and issues associated with scale‐up of the two technologies and conduct a market study to identify potential applications for the CPV/SWRO system within the Middle East region. Desalinated Water Quality Blending Study San Diego County Water Authority, California CH2M HILL conducted executed a water quality study for the San Diego County Water Authority (SDCWA) to define the interaction between desalinated seawater containing varying levels of bromide to be produced by the Carlsbad Seawater Desalination Facility with two different existing treated surface waters distributed by the SDCWA throughout their service area. An initial review focused on the impact of desalinated water bromide on degradation of chloramine residual and the impact of the desalinated water on blended water pH, alkalinity and TOC. Results from the review were used to prepare a bench‐scale testing protocol that defined a comprehensive series of experiments to both quantify chloramine reduction following blending at different ratios, desalinated water bromide level, residence time between desalinated water chloramination and blending and point of re‐ chlorination. The results were used to establish design criteria for design and construction of additional chlorine (and ammonia) boosting facilities at SDWCA’s Twin Oaks Valley WTP as necessary to maintain a target chloramine residual in the blended and distributed waters. Stock Island and Marathon SWRO Water Treatment Plants Florida Keys Aqueduct Authority, FL CH2M HILL successfully delivered the Authority’s two RO seawater WTPs on budget and schedule. Since 1984, CH2M HILL has worked closely with FKAA and a multitude of stakeholder groups to seek ways to improve the water systems in the Keys. We worked with FKAA to design and construct two RO desalination plants that treat seawater to drinking water standards as an emergency source of water for the Keys; one is located on Marathon to supply the Middle Keys and one is on located Stock Island to supply Key West and the Lower Keys. CH2M HILL designed and provided engineering services during construction for these two seawater RO plants, which have a total capacity of 3 mgd. We also recently provided design, permitting, bid phase, and construction management services for a 6 mgd brackish water RO WTP in Florida City to improve the sustainability of the FKAA water system. Seawater Desalination Facility Planning Study Massachusetts American Water Company, Hingham, MA CH2M HILL conducted a planning study for a 500,000 gpd SWRO facility treating open intake surface seawater in Massachusetts. The project included the site planning, conceptual design, and cost development of a seawater facility with intake, dual pressure filter pretreatment system, and post treatment facilities. Study examined current and anticipated water treatment and water supply regulations, site constraints, raw water quality, treatment options, residuals disposal, capital costs, and operation and maintenance costs. Menifee, Perris I and Perris II Desalters Eastern Municipal Water District, Sun City, CA CH2M HILL planned, piloted, designed and provided engineering construction services for the 2.5 mgd Menifee, the 4.5 mgd Perris I, and the 3.5 mgd Perris II desalination facilities. All three facilities are located on the same site and consist of a number of facilities including feed water flow control facilities, RO buildings, bulk chemical storage and pumping areas, brine pump station, chlorine contact tank, and administration building. The RO buildings house cartridge filters, RO feed pumps, two‐stage RO skids and permeate decarbonation facilities. The RO systems are designed to accommodate the anticipated range of groundwater TDS (3,000 to 7,000 ppm). Hydraulic turbochargers extract and transfer residual pressure energy from second stage concentrate to second stage feed, reducing first stage feed pressure and flux as well as reducing energy use and first stage fouling potential III‐19 RO Water Treatment Plant Coral Springs Improvement District, FL The CSID RO Facility is designed with the flexibility to soften and remove organics from an existing freshwater facility with the capability to treat brackish water in the future. CH2M HILL designed a new 7.5‐mgd RO facility that treats existing Biscayne freshwater wells and is designed to treat future brackish Floridan well water. The new facility replaces an existing lime softening treatment process at the existing Coral Springs WTP site while using the existing finished water storage and pumping, wellfield, and chlorination facilities. The new treatment process includes sand strainers, cartridge filters and chemical pretreatment, bypass blending, three RO trains, degasifiers, finished water clearwell, post‐treatment chemical stabilization, and transfer pumping to existing finished water storage. CH2M HILL helped the District find a cost‐effective and sustainable treatment solution that met project drivers such as the need to replace aging water treatment infrastructure and ability to treat alternative Floridan brackish water in the future. Tuas Desalination Plant, Singapore Public Utilities Board, Singapore PUB is committed to providing its customers with a safe and reliable supply of high‐quality drinking water. To further increase the availability and reliability of supply of desalinated water, PUB has undertaken a third seawater reverse osmosis (SWRO) desalination plant at Tuas (TDP3) using a design‐build approach. TDP3 will deliver potable water into PUB’s distribution network and will occupy a 3.5‐ha plot of land located at the far western side of the island (fronting Tuas South Avenue 3), which currently separates the SingSpring and Tuaspring desalination plants. The seawater quality at the intake is critical in designing the overall treatment process. Key considerations for design and selection of the pre‐treatment process include suspended solids, turbidity, TOC and potential for algal blooms. Key considerations for design of the RO process include total dissolved solids, boron and temperature. There is a concern that TSS levels may increase in the future as a result of possible future dredging activities associated with various land reclamation projects in the vicinity of the Johor Straits and the TDP3 intake. With the current TSS levels, DAF followed by membrane filtration is proposed as the preferred pre‐treatment process as typical practice has been to provide solids removal (such as sedimentation or dissolved air flotation (DAF)) upstream of membrane filtration when TSS levels exceed around 20 mg/L in order to maintain high design fluxes and recoveries. The plant has been designed for an effective operating range of 6.6 to 36 mgd. The treatment process for the desalination plant consists of DAF followed by a dual membrane system using ultrafiltration (UF) followed by 1st – and 2nd‐pass RO, then by disinfection and post treatment chemical addition. The treatment process includes treatment screening, intake pumping, intake chlorination, treated water tanks and pumps, outfalls, and ancillary systems. CH2M is providing preliminary design, preparation of a design‐build tender, EIA studies and security assessments, engineering services during construction, and site supervision. Preliminary design activities include:  Data analysis provided by PUB regarding feed water quality and product water quality objectives;  Collection and analysis of additional water samples  Engage global technology experts within CH2M and, in collaboration with PUB, select appropriate treatment processes  Collect best practice and lessons learnt from similar projects globally and in Singapore  Conduct workshops on process design, value engineering and layout options with PUB and key stakeholders  Cost estimating in conjunction with PUB and key stakeholders III‐20  Develop the preliminary design for the preferred design option  Develop and optimize the intake and outfall design and locations  Develop and optimize the security conceptual designs  Develop Preliminary Design Report for PUB Barka I, Phase 2 Seawater Desalination Plant, ACWA Power Barka, Oman ACWA Power Barka (APB) appointed CH2M to act as Owner’s Engineer for a new 12.5 MiGD Seawater Reverse Osmosis (SWRO) plant near its existing Barka 1 integrated water and power plant (IWPP) facility.

Manufacturers of main SWRO equipment include Degremont ‐ RO equipment supplier, Hydranautics ‐ membranes, Torishima – high pressure pumps and ERI ‐ energy recovery devices CH2M Role/Responsibilities: CH2M is responsible for review of Hyundai Engineering and Construction Company Limited (Degremont is their subcontractor) desalination plant design including DAF, 2 pass media filtration, 2 pass RO (Ten 1st pass RO Trains, three 2nd pass RO Trains). Supply of Seawater Desalination Plants, Sharjah, United Arab Emirates Sharjah Electricity and Water Authority The Layyah SWRO plant is located within the Arabian Gulf, characterized by seawater that is high in temperature and salinity and subject to algal blooms (red tie). To ensure adequate quality RO feed water, pre‐treatment includes 3‐ millimeter (mm) screening, dilution/attenuation, and two‐stage media filtration. The Kalba and Khor Fakkan plants are located in the Gulf of Oman, where seawater quality is less challenging. The Layyah SWRO Desalination Plant produces 6 mgd of permeate from Arabian Gulf seawater (TDS: 42,000 mg/L). Subject to frequent Red Tide events, the plant uses a state‐of‐the‐art pre‐treatment system including using pre‐treatment consisting of coagulation, flocculation, DAF and Dual‐Stage Pressure Sand Filters to mitigate the fouling effects of Red Tide. The Khor Fakkan SWRO Desalination Plant also produces 6 mgd of permeate from seawater withdrawn from the Gulf of Oman using pre‐treatment consisting of coagulation, inline flocculation and Dual‐Stage Pressure Sand Filters. The Kalba SWRO Desalination Plant, located near Fujairah, produces 3 mgd of permeate from seawater extracted from the Gulf of Oman using a pre‐treatment scheme consisting of coagulation, inline flocculation and NORIT Seaguard UF Membrane Filtration. CH2M Role/Responsibilities: CH2M served as the single source of responsibility for EPC services for delivery of two seawater RO treatment plants with a total capacity of 15 mgd, expandable to 32 mgd. CH2M was responsible for design, procurement, mechanical/electrical design, guarantee of water output, guarantee of electricity consumed per m3 of produced desalinated water. Pre‐treatment at Khor Fakkan included passive 3‐mm screening and two‐stage media filtration, while at Kalba pre‐ treatment was achieved through UF membranes with upstream protection by passive screening and pre‐filtration screens. Onsite pilot testing was conducted to verify UF performance and design parameters. The Layyah and Khor Fakkan sites used dual‐stage media filters for treatment of the raw seawater prior to reaching the high‐pressure SWRO system. The Layyah site incorporated a DAF system before the media filters for enhanced removal of particulates, and better protection against accidental oil spills and seasonal algae blooms. Instead of conventional media filters, the Kalba desalination plant used high‐performance ultrafiltration membranes that are specifically designed for SWRO pre‐treatment applications. All three plants incorporate the highest efficiency energy‐recovery devices available on the market. These innovative technologies result in the production of desalinated seawater at lower capital and operating costs than conventional systems. III‐22 Wonthaggi Seawater Desalination Plant, Melbourne, Australia Melbourne Water Corporation The Melbourne Water Corporation (MWC) selected CH2M to provide expert advice relative to the upcoming seawater desalination plant being procured through the Department of Sustainability and Environment for MWC. Because of the magnitude of the project, one of the world’s largest RO plants—cost, environmental and public acceptance issues were integral to the project’s success. CH2M Role/Responsibilities: CH2M has worked closely with MWC and their consultants to resolve technical issues regarding finished water quality, cost implications of low total dissolved solids requirements, setting of boron and bromide water quality limits, post‐treatment alternatives for blending purposes, and public acceptance. Of particular sensitivity is TDS levels, boron and bromide concentrations in the finished water while maintaining overall low corrosivity to long transmission lines and distribution systems, and minimization of customer impacts from boron and TDS. PowerSeraya Seawater Reverse Osmosis Plant, Jurong Island, Singapore PowerSeraya The PowerSeraya Seawater Desalination Plant Project is the world’s first full‐ scale desalination plant to use a large‐diameter SWRO technology. The desalination plant is located on the site of PowerSeraya’s existing Pulau Seraya Power Station, a 3,100 MW power plant. The desalination plant is located on Jurong Island, a unique cluster of the major oil, petrochemical, and specialty chemical industries of Singapore. The desalination plant features granular media filtration pre‐treatment and a two‐pass RO system. CH2M Role/Responsibilities: In late 2005, PowerSeraya engaged CH2M in a consultancy assignment to conduct a feasibility study and functional design for a new SWRO desalination plant at the Pulau Seraya PowerStation. CH2M took advantage of the power station’s existing infrastructure of cooling water intake, discharge out falls, and onsite tank age to co‐site the new desalination plant at the power station, resulting in an estimated 25 per cent savings in capital costs for new infrastructure. CH2M also served as the EPC contractor responsible for the design, procurement, construction, and commissioning of the new SWRO desalination plant in Singapore. Southern Seawater Desalination Plant, Binningup, Australia Water Corporation The Southern Seawater Desalination Plant, located in Binningup, was constructed in 2 stages – each capable of producing 36 mgd of water per year. The first stage began producing and supplying drinking water to the Water Corporation’s Integrated Water Supply Scheme in March 2012 and the plant is currently producing approximately 72 mgd. The plant’s energy requirements are offset by energy purchased from various renewable energy generators, including wind and solar farms near Geraldton. CH2M Role/Responsibilities: CH2M is the owner’s engineer and independent third‐party reviewer responsible for:  Independent technical advice during the Alliance Establishment Stage III‐23  Advice and technical input to Water Corporation during workshops and design presentations during the Alliance Development Stage  Preparation of a tender evaluation report to inform and assist Water Corporation with the shortlisting of four proponents from a field of six during the Alliance Establishment Stage  Advice and guidance to select the final shortlist of two proponents to proceed to the Alliance Development Stage  Preparation of proponent questionnaires and interview questions  Technical memos and key advice during the Alliance Establishment Stage  Independent third‐party reviews for all process design including, pre‐treatment, RO, and post‐treatment processes  Independent third‐party reviews for geotechnical, structural, durability, mechanical, civil, electrical, and instrumentation and controls.

National Centre of Excellence in Desalination – Detailed Design, Western Australia, Murdoch University The detailed design of a world‐class desalination pilot‐scale testing and research facility. The Facility has been designed to be a flexible, modular in design to allow testing of multiple innovative and emerging technologies, it will be highly instrumented providing advanced data acquisition. Water supplied from brackish and seawater bores, mixing is through a flexible tank arrangement and delivery to multiple points around the site. Chemical cleaning and neutralization system with disposal to sewer and Managed Aquifer Recharge of brine and product water. CH2M Role/Responsibilities: CH2M carried out the detailed design and procurement management for the center with capacity to deliver feed water for use in multiple pilot scale technologies. A detailed smart piping model was prepared using Autodesk Revit MEP to provide clarity of location and interactions of pipework. CH2M also used its contacts to find and encourage sponsorship of the facility through vendors providing equipment for use in the center. Feed waters to the facility for testing and research come from two extraction bores located on site. The bores provide freshwater and seawater directly to the tank farm location. Construction of the bores was supervised by CH2M during the conceptual phase of the project. The bore water is delivered to a tank farm consisting of three (3) feed water tanks and a service water tank to allow mixing of constitute parts to achieve a wide range of water characteristics. Brine and product water collected from pilot trial area can be discharged to a re‐injection bore via a managed aquifer recharge system. The feed water is distributed around the facility by three (3) delivery mains. Service water is delivered through a fourth main. There are nine (9) Tie‐In points available for pilot plants around the facility, power and control cables are also available from three test bay supply boxes. Data from the pilot plants is measured via an instrumentation skid, the skids include multiple instruments measuring flow, pH, conductivity, ORP, temperature etc. III‐24 QGC Value Engineering Independent Review, Queensland, Australia QGC QGC are in the process of ramping up gas production in line with their program to begin exporting LNG. The ability to manage the treatment and disposal / re‐use of the associated water is critical to ensure gas production targets are met. QGC required certainty that the water management and treatment facilities will be sufficient in terms of capacity, availability and reliability. The four water treatment plants include an RO system as a critical process unit, were reviewed at various stages of operation, commissioning, construction and design. At the commencement of the engagement, the online treatment plants (two of four) were operating well below design capacity due to water quality and operational constraints. The two treatment plants under design and commissioning at the time of CH2M’s review (i.e. review underway prior to operation) had a combined design capacity of 48 mgd. CH2M Role/Responsibilities: CH2M completed a value engineering independent review of QGC’s water treatment system that will receive coal bed seam water from the QGC Queensland Curtis liquefied natural gas (QCLNG) development in the Surat Basin, Queensland. Reynolds Desalter Expansion Sweetwater Authority The Sweetwater Authority is expanding the capacity of the Richard A. Reynolds Groundwater Desalination Facility. Built in 1999, the facility’s current production capacity is 5 million gallons per day (mgd) from six wells. This consists of 4 MGD reverse osmosis product water blended with 1 mgd of water treated only for iron and manganese removal via pyrolusite filters. The expansion will double the production to 10 mgd, with the addition of five new wells and three new RO treatment trains. The new RO trains are to include turbochargers for energy savings and flux balancing. The upgrades also include the implementation of upgraded system controls and automation enhancements to the existing and new groundwater wells. 15,700 feet of new pipelines are being installed to convey groundwater to the new treatment facility and the concentrate control disposal pipeline is being relocated. In addition, the RO clean in place and neutralization systems are being replaced. CH2M Role/Responsibilities: CH2M is owners engineer for the expansion with the following responsibilities:  Design and construction phase services of the iron and manganese treatment system added in 2009.  Environmental Services for CEQA/NEPA Compliance  Preliminary design of the expansion  Final Design of the Desalter Expansion including Construction Phase Services  Well drilling, equipment and buildings  SCADA and Automation Coordination III‐25 Menifee and Perris I Desalters, Eastern Municipal Water District Eastern Municipal Water District The Menifee and Perris I Desalter Facilities treat groundwater extracted from the Menifee and Perris sub‐basins, and produce 7.5 mgd of desalinated water (product water), with Menifee producing 3 mgd and the Perris I facility 4.5 mgd. The product water is then blended with 1.5 mgd of brackish groundwater for a total treated water flow of 9 mgd. By pumping and treating brackish groundwater, the facility reduces salinity within the San Jacinto Basin and helps the District reduce their dependence on imported water from the Colorado River and State Project water systems. Salinity reduction is achieved through the use of RO, a pressure‐driven membrane process that retains the salts using a semi‐permeable membrane. The Desalter Facility is located in Sun City, California. The facility’s process building houses the two desalters in separate but adjacent areas. Each area includes cartridge filters, high pressure pumps and RO trains, as well as a chemical cleaning system. Facilities for neutralization of spent cleaning solutions are also housed within the building but in a separate room. Enclosed chemical storage and feed systems are provided for scale inhibitor, sulfuric acid, caustic, and onsite hypochlorite generation. Outside facilities include decarbonators to remove excess carbon dioxide from the RO permeate; a chlorine contact basin to provide for virus inactivation of the combined RO product and bypassed well water; and a brine pump station. Following disinfection and storage, the treated water is delivered to the water distribution system and combined with other treated water supplies. The facility also has a separate administration building with a control and operations room, conference room and rest rooms. Each RO train at the Perris I Desalter includes a PEI hydraulic turbocharger to reduce energy consumption by recovering residual energy in the RO concentrate. After entering the brine pump station, the RO concentrate is pumped into the Santa Ana Regional Interceptor brine line for ultimate discharge to the Pacific Ocean. The Menifee Desalter was commissioned in 2001 and the Perris I Desalter in 2007. Both desalters have operated nearly continuously since commissioning. CH2M provided operational assistance during commissioning and start‐ up of the Perris I Desalter and follow‐on tailored training of desalter facility operations staff. We also assisted District staff in conducting testing to increase the recovery of the desalters from 70 to 75 percent, resulting in additional treated water production and, more importantly, reduced cost for RO concentrate disposal. CH2M Role/Responsibilities: CH2M developed the project design, performed structural, mechanical, process and electrical engineering, construction management and prepared environmental documents & permits. J. Robert Dean WTP Florida Keys Aqueduct Authority, FL For decades, South Florida has relied on the Biscayne Aquifer, a thin lens of fresh water 30 to 100 feet below the surface, for its drinking and irrigation water. But an ever‐growing population, combined with long spells of dry weather, prompted Southwest Florida Water Management District to limit the amount of fresh water drawn from the Biscayne Aquifer. The desalination facility was added to the Florida Keys Aqueduct Authority’s (FKAA's) existing 23‐mgd treatment plant to tap into brackish waters of the Upper Floridan Aquifer, located approximately 1,200 to 1,300 feet below the surface. The RO system is designed to desalt feed water with salinities from about 5,000 to 8,000 mg/L TDS. CH2M Role/Responsibilities: CH2M designed, permitted, and provided construction management services for the project. Additionally, we provided the control programming services. The design of the RO facility included supply wells and raw water III‐26 transmission mains; pretreatment; brackish water RO membrane treatment; disinfection; post‐treatment and blending; and concentrate disposal transmission and injection wellhead facilities. The RO facility is designed to be fully integrated with the existing lime softening treatment process at the plant, which treats "fresh" Biscayne Aquifer groundwater. The blended lime softening and RO desalted product waters from the two treatment processes continue to meet FKAA’s potable water production and water quality goals. The new facilities include 6 mgd of membrane permeate capacity. The RO system consists of four 1.5‐mgd, two‐stage process trains, each with dedicated feed pumps and energy recovery hydraulic turbochargers. The turbochargers transfer excess energy from the waste concentrate flow streams to boost the feed pressure to the second stage RO membranes. This not only minimizes energy consumption but better balances the flows through the system and improves RO performance. “CH2M has a long‐standing history of providing high‐quality professional engineering and multi‐discipline utility services to support the Florida Keys Aqueduct Authority's water resources needs, including several desalination projects. …They are very technically competent and have cost‐effectively and efficiently managed and delivered our projects.
