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.

STATEMENT OF WORK
COLLIER COUNTY
ALTERNATIVE WATER SUPPLY PROJECTS FY12
INTRODUCTION
The Collier County Alternative Water Supply projects are part of a comprehensive plan to
improve and expand the County's alternative water supply sources to meet the increase in
potable and irrigation water demand. 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.

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.
