Agenda 11/13/2012 Item #16C511/13/2012 Item 16.C.5. EXECUTIVE SUMMARY Recommendation to accept Amendment No. 01, a zero dollar time extension to the South Florida Water Management District Alternative Water Supply Grant 4600002535. OBJECTIVE: Allow remaining South Florida Water Management District (SFWMD) Alternative Water Supply (AWS) Grant revenue of $100,000 for Project 2, Aquifer Storage and Recovery (ASR) Well Project, to be invoiced during FY2013. CONSIDERATIONS: On June 24, 2008, Agenda Item 10G, the Board of County Commissioners (Board) adopted the 2008 Wastewater Master Plan Updates that identified requirements for the Aquifer Storage and Recovery (ASR) Well Project. The proposed scope of work is consistent with the 2008 Wastewater Master Plan Update, Project 74030 "Irrigation Quality Water Aquifer Storage and Recovery (ASR) Well," Section 8, Table 8 -1, page 7 of 7, line 148. The project is consistent with the 2010 Wastewater CIP Update page 3 of 4, line 93, as identified in the 2011 User Fee Rate Study. On February 28, 2012, Agenda Item 16C2, the Board accepted SFWMD AWS Grant 4600002535 partially funding two separate AWS projects, "Project 1," the Reverse Osmosis Treatment Units Replacement and Inter -Stage Booster Pump Project; and, "Project 2," the Aquifer Storage and Recovery (ASR) Well Project. A time extension of the grant is needed to invoice remaining grant funds in FY2013. Project 2, the ASR Well Project, was delayed for various reasons: • Unanticipated testing during design. • Extended bidding process. The lowest bidder was not a local vendor. The second lowest bidder was a local vendor who initially agreed to accept the contract at the lower price, and then changed that decision. • The lowest bid ($1,042,050) was higher than the original estimate provided in the contract ($700,000), and additional project funds were required. • There was no Board meeting in August to facilitate an earlier approval. Grant funding for "Project 1" was invoiced and received during FY2012. This time extension will allow the remaining grant revenue for Project 2 to be invoiced during FY2013. FISCAL IMPACT: Remaining grant revenue of $100,000 will be realized upon completion of work during FY2013. Funding source is the Wastewater User Fees fund 414. To recognize grant funds and match funding, three budget amendments were required: 1) $500,000 from Fund 414— County Sewer Capital Project, to Fund 414— Reserve /Transfer; 2) $500,000 from Fund 414 - Reserve /Transfer, to Fund 417— Public Utilities Match; and, 3) $100,000 to Fund 416 — Public Utilities Grant recognizing SFWMD grant funding award. These amendments were approved and executed by the action taken at the Board's February 28, 2012, meeting under agenda item 16C2. Packet Page -1983- 11/13/2012 Item 16.C.5.

The County has requested cooperative funding for the following two projects scheduled for completion in FYI 3: • Reverse Osmosis Treatment Units Replacement & Installation Inter -stage Booster Pump Installation • Aquifer Storage & Recovery (ASR) Well at Livingston Road L0. PROJECT 91 :North County Regional Treatment Plant (NCRWTP)- Reverse Osmosis Treatment Units Replacement & Installation Inter -stage Booster Pump The North County Regional Water Treatment Plant (NCRWTP) has an 8 MGD Brackish Water Reverse Osmosis (BWRO) system. Collier County Public Utilities would like to evaluate the BWRO membranes with the existing BWRO skid configuration with the addition of interstage booster pumps between the first stage and second stage pressure vessels. Installing interstage booster pumps would benefit the RO system. Advantages of using these pumps are reduced feed pressure requirements, extended membrane life expectancy, enhanced hydraulic control over the membrane system (i.e., improved flux rate balance at each stage) and reduced energy and power consumption. Installation of the interstage booster pumps requires modifications to the interstage and concentrate piping, along with the instrumentation and control system. The use of interstage booster pumps allows for substantial O &M cost savings per year for the RO process. The power cost savings combined with the assumed increase in membrane life (5 to 7.5 years), saves approximately half a million dollars per year in O &M costs. 1.1 OBJECTIVES The objective of this project is to replace the RO membrane cartridges in the four (4) BWRO skids located on the east side of the RO building. The project will also include design modifications to the existing skids to add interstage booster pump capability. Agreement No. 4600002535, Exhibit "A1 ", Page 1 of 3 Packet Page -1989- 11/13/2012 Item 16.C.5. 1.2 SCOPE OF WORK The work includes a design report for the membrane /interstage booster pump project, engineering drawings and specifications, bid and construction phase support, and start up support. Collier County will procure the new BWRO membranes, remove the old BWRO membrane modules, and install the replacement BWRO modules. In addition, the installation of the interstage booster pumps and piping modifications to the four (4) existing BWRO skids will be procured by Collier County and coordinated with the replacement of the membranes. 13 WORK BREAKDOWN STRUCTURE The major tasks and task descriptions that will be necessary for the completion of the scope of work are as follows. Task 1: Engineering, Design, Permitting, and Construction Management of Project Task 2: Membrane Procurement and Installation Task 3: Installation of Inter -stage Booster Pumps and RO- Membranes 2.0 PROJECT #2: Aquifer Storage & Recovery (ASR) Well at Livingston Road Collier County Public Utilities Division (CCPUD) has invested heavily in the development of a expansive irrigation quality (IQ) water system as part of an overall commitment to a sustainable total water management program. However, even with the extensive reuse program that the County has in place, during rainy.periods when irrigation demand is low, excess reclaimed water must be disposed of using percolation ponds and deep injection wells. To better manage its reclaimed water resource, the County developed an IQ water ASR system, the initial phase of which was completed in 2007. The County ASR system was designed for expansion to a total of five ASR wells. As a continuation of the IQ water ASR program, the County is working to construct a Non - Underground Source Drinking Water (Non -USDW) ASR well at the Livingston Rd ASR welifield. The development of a Non -USDW ASR well will allow greater flexibility in meeting regulatory requirements when storing excess reclaimed water. The flexibility will allow CCPUD to utilize reclaimed water more effectively; reducing irrigation withdrawals from surface or groundwater systems during critical dry season periods and reducing loss of valuable freshwater resources. For these reasons, the use of ASR wells for storage of reclaimed water is consistent with the goals and objectives of the Big Cypress Basin of the South Florida Water Management District and is an excellent candidate for Alternative Water Supply (AWS) funding. The proposed project includes the extension of an existing ASR to tap a Non -USDW aquifer that will serve as the storage zone capable to receive a maximum of 2.0 million gallons per day. Agreement No. 4600002535, Exhibit "Al", Page 2 of 3 Packet Page -1990- 11/13/2012 Item 16.C.5. 2.1. SCOPE OF WORK The scope of the project is to construct a Non -LTSDW ASR well by extending the existing ASR Well. The project will create a facility for the storage and recovery of more than 140 million gallons of reclaimed water. It is anticipated that upon completion, the proposed well would accept and recover water at a rate of 1.0 to 2.0 MGD. The injection will occur over a 90 to 120 - day period during the wet season, or whenever excess wastewater was available. The Non -USDW ASR well will be completed with a 12 -inch diameter casing to approximately 1,450 feet below land surface (bIs) and an open hole extending to approximately 1,475 feet. The final depths will be determined from subsurface data obtained during well construction. The project will be comprised of the following construction elements: 1. Pilot hole drilling and testing of identified Non -USW storage zone (monitoring well) 2. Construction of non -USDW ASR well and testing (injection well) 3. Installation of submersible pump and above ground appurtenances 2.2 WORK BREAKDOWN STRUCTURE The major tasks and task descriptions that will be necessary for the completion of the scope of work are as follows: Task 1:. . Pilot hole drilling and testing of identified Nan -USW storage zone Task 2: Construction of a Non USDW ASR Well and testing Task 3: Installation of submersible pump and above ground appurtenances 2.3 PROJECT COST The construction cost of the proposed ASR well project is estimated with $1,042,050. 2.4 PROJECT LOCATION The project is located north of the IQ Water Wellfield, off Livingston Road in Collier County. The injection well and monitor wells will be installed on easements obtained by the County. Agreement No. 4600002535, Exhibit "At ", Page 3 of 3 Packet Page -1991- 11/13/2012 Item 16.C.5.
