pressure pumps, RO skids and appurtenances. Tetra Tech also provided the design, permitting, and constructionservices for the expansion to 10.0 MGD. The raw water for the new ROWTP is supplied from the new Floridanaquifer wellfield that was also designed by Tetra Tech and constructed under a separate construction contract.

The City of Port St. Lucie once again selected Tetra Tech to design and manage construction of a ROWTP at thegreenfield LTC Ranch Site. The water facility had an initial capacity of 6.0 MGD and was also designed with theability to readily expand to a capacity of 22.5 MGD. Tetra Tech provided a facility design for the initial capacityallowing for phased construction and start-up of the proposed facilities to meet the City's rigorous schedule foradditional capacity. In 2005, the City authorized Tetra Tech to begin design for the facility expansion to a totalcapacity of 20.0 MGD. The raw water supply facilities consist of 10 offsite brackish wells with remote telemetryand auxiliary power, one onsite supply well, one onsite blend well, and two raw water mains.

Tetra Tech has the unique qualifications of both the raw water supply wells and the design of the RO treatmentsystems. This complete system knowledge will provide the City with a highly experienced and qualified teamthat has a complete understanding of all aspects of this assignment and your goals.

Committed Team Leadership

Tetra Tech has assembled a premier team with the demonstrated experience and understanding of currenttechnologies needed to provide a successful pilot test. Project Manager Jarrett Kinslow has led numerousprojects involving reverse osmosis for brackish water and conducted pilot tests for multiple RO plants. Hisextensive experience and detailed understanding of the JEA plant extends back to the initial planning starting in2001, continuing through all phases of construction that were completed in 2008. Additionally, Tetra TechDrinking Water National Practice Leader James Christopher has served as the project manager for both thePineville ROWTP and the James E. Anderson ROWTP expansions. He has an unmatched knowledge of bothfacilities providing tremendous value to the City for this proposed project. Since the completion of the JEAprojects for the City, both James and Jarrett have continued to work as a team on recent projects that havecontinued to expand our design capabilities for such systems. By pairing this additional experience with ourunderstanding of the plant, Tetra Tech can help the City benefit from our knowledge of the latest technicaladvances, while also providing a cost-effective and rapid response to the City's needs, which will create aseamless approach to conducting the pilot test.

Pilot Testing Experience

Tetra Tech has a significant amount of experience in the development and implementation of more than adozen pilot-scale and bench-scale treatment studies to select processes for the design of new water treatmentfacilities, and for improvements and upgrades to existing facilities for regulatory compliance, and/or processenhancements to increase the treatment effectiveness. An owner needs input from a consultant that not onlyhas the pilot testing experience, but also has the experience and "lessons learned" from translating pilot testingresults into full scale design.

For the City of Clearwater, Tetra Tech proposed, piloted, and designed a pilot treatment system to demonstratethe capability of the system to treat reclaimed water to meet all of the regulations for indirect potable reuse.The pilot system mimics the full-scale system, which included three membrane processes, ultrafiltration, reverseosmosis, and membrane contactors. The pilot system included a first-of-its kind, post- treatment system thatstabilizes the purified water through calcium remineralization and oxygen removal to stabilize the water. TetraTech was responsible for managing the operation, troubleshooting and water quality sampling during the one-year pilot. In addition, one of the earliest pilot tests for Orange County was conducted by Tetra Tech to use NFmembranes for lower energy potable reuse.

This data was in turn usedto estimate the yield of the proposed wells, design of the pumps and motors, and provide basic datafor the groundwater flow model.

Process/mechanical equipment included within the facility includes micron filtration, high pressurepumps, reverse osmosis, chemical feed including anti-scalant, sulfuric acid, sodium hydroxide, poly-phosphate, chlorine and ammonia, forced draft degasification, odor control, high service pumpingfacilities, back-up power facilities and intermediate pumping facilities. The RO treatment facilitiesconsist of ten RO skids that are 2.0 MGD each and divided into two separate trains for operationalredundancy. Each train includes chemical pretreatment via sulfuric acid and scale inhibitor, followedby physical pretreatment via micron filters. The RO treatment skids are fed by dedicated highpressure pumps and feature interstage boost via energy recovery turbines. The post treatmentprocesses include raw water blending, fluoridation, degasification, disinfection, and stabilization. Theconcentrate from the RO process is disposed of via an onsite deep injection well.

Direct Potable Reuse Demonstration Project, Daytona Beach, Florida

Project Team:Jennifer Ribotti, PE,Jarrett Kinslow, PE,Dave MacNevin, PhD, PE,James Christopher, PE

Project Duration:Ongoing

Project Value:$423,000

The City of Daytona Beach is facedwith investigating alternative watersupplies to meet growing potablewater demands while complyingwith more restrictive nutrientdischarge limitations associatedwith the City's effluent disposaloutfall. As a result, the City initiatedthe Direct Potable Reuse (DPR)Demonstration Program todetermine the feasibility of potable

reuse as a source water supply.

The DPR Demonstration Program includes a $3.1 million "demonstration scale" advanced waterpurification system. The project was identified by the St. Johns River Water Management District asan innovative alternative water source project for its potential to address two emerging issues withone solution: by improving the City's local impaired river water quality through eliminating effluentdischarge and offsetting current groundwater withdrawal practices.

The program began in 2015 with a feasibility study investigating both indirect potable reuse (IPR)and direct potable reuse (DPR) relative to exploiting more conventional water resources. Thefeasibility study was performed by Tetra Tech, which later assisted in preparing and finalizing theDistrict Funding Application on behalf of the City. The contract for the DPR Demonstration TestingSystem (DTS) was awarded in April 2016 to Tetra Tech with services including design, bidding andconstruction management services. Public outreach campaign services are also being provided.

Construction of the system is underway, and after completion, will operate for two years, testing avariety of operating scenarios. A unique aspect of the project includes the testing of eightdifferent membrane modules and elements for both the ultrafiltration and reverse osmosissystems. A robust sampling plan will verify the effectiveness of the system and provide confidenceto the public and regulatory agencies that both regulated and non-regulated constituents are beingremoved.

The Demonstration Testing System will add full advanced treatment (FAT) to the City's existingWestside Regional Water Reclamation Facility (WRWRF) to purify approximately 200,000 gpd ofreclaimed effluent. The WRWRF currently practices advanced wastewater treatment with ultravioletlight for disinfection. The FAT process for the DTS has been widely proven in potable reuse projectsaround the country and uses an integrated membrane system with advanced oxidation.

• Membrane filtration stage (Ultrafiltration): Provides initial removal of suspended solids andvirus and pathogen removal and acts as a solids barrier for the subsequent membrane stage,which extends the useful life of the membranes

• Membrane separation stage (RO): Provides an additional barrier for viruses and pathogens,as well as a removal mechanism for a majority of organics, inorganics, heavy metals, bacteria,pharmaceuticals, and personal care products

• Advanced Oxidation with ultraviolet light (UV-AOP): Provides an additional barrier againstviruses, nitrosodimethylamine (NDMA) and reduces trace levels of low-molecular-weightorganics, constituents that pass through the membrane stages.

The purified water produced from the Demonstration Testing System is anticipated to exceed allcurrent drinking water standards and will be tested for a variety of microconstituents,pharmaceuticals, and personal care products (PPCPs).

Shell Creek WTP RO Upgrades, Punta Gorda, Florida

The City of Punta Gorda (City) ownsand operates the Shell Creek WaterTreatment Plant (SCWTP), which treatssurface water from Shell Creek that isimpounded by the Hendrickson Dam.The SCWTP is rated for a treatmentcapacity of 10.0 MGD and serves asthe primary source of potable watersupply for the City of Punta Gorda. Inaddition, the City owns and operates a2 MGD aquifer storage and recovery

(ASR) system to augment potable water supply. Typically, during the dry season, Shell Creekexperiences elevated levels of total dissolved solids (TDS) and the existing SCWTP process cannotreduce the raw water TDS levels to less than the secondary maximum contaminant level (SMCL) of500 milligrams per liter (mg/L) in the potable water. The City petitioned the FDEP for an alternativeSMCL of 1,000 mg/L. The FDEP issued a variance to allow the alternative TDS level of 1,000 mg/Luntil June 15, 2011. By June 15, 2011, the City was required to meet the SMCL of 500 mg/L. For theCity to meet this deadline, advanced water treatment needed to be installed at the SCWTP andadditional raw water supply needed to be developed.

To address the TDS requirements, as well as an administrative order to remove arsenic from theASR wells and discontinue the use of the ASR wells, the City retained Tetra Tech to perform thepreliminary and final design for the development and implementation of a new groundwater sourceand a new RO treatment system. The objective of this Project is to reliably produce an annualaverage of 10 MGD of potable water at the SCWTP that meets drinking water standards by utilizingRO to treat groundwater and then blend with the existing surface water treatment process. Toaccomplish this task, existing ASR wells were converted to groundwater wells, therebyaccomplishing two goals: 1) the arsenic will be removed through the RO process and injected into anew deep injection well, and 2) the use of existing ASR wells will reduce drilling costs for adding newsupply wells. New supply wells were added as part of this project, but the use of existing ASR wellsreduces the number of new wells required.

The new RO treatment system treats an initial capacity of 3.0 MGD, expandable to 8.0 MGD. TheRO permeate will blend with the treated surface water in a blending tank prior to final storage anddistribution. Final chemical dosing for disinfection will be accomplished in the blending tank.

The City of Tarpon Springs historicallysupplied their customers with a mix of a freshCity groundwater supply and waterpurchased from Pinellas County through abulk service agreement. The City decided toconstruct an alternative water supply andtreatment facility to support their customerdemands using the design-build deliverymethod. The facility utilizes water from theupper producing zone A of the FloridanAquifer, and the concentrate is disposed ofby surface water discharge into the coolingchannel for the Anclote Power Plant. The

City obtained for the project the water use permit and drilled the 15 supply wells, cooperative fundingfrom the SWFWMD, the FDEP construction permit, and the NPDES discharge permit. The Cityselected the design build team of Wharton Smith, Inc., Tetra Tech, Inc., and Harn R/O to provide allthe design, permitting, and construction services necessary to complete the project and place it intoservice.

Tetra Tech provided a full range of engineering services including preliminary engineering, finaldesign, permitting, construction administration, start-up, and testing. The project consisted ofequipping the 15 raw water supply wells, construction of over 14,000 linear feet of 8-inch to 24-inchraw water transmission mains, construction of a 16,000-square- foot pre-engineered metal building, anew reverse osmosis water treatment plant (ROWTP) capable of treatment up to 6.4 MGD on amaximum daily demand basis, and construction of more than 14,000 linear feet of 16-inchconcentrate force main. The RO treatment system consisted of three 2.13 MGD RO skids loadedwith Dow Filmtec seawater membranes to treat a raw water with up to 16,600 mg/L TDS, which arefed by two 450 horsepower feed pumps in series. This project also included the design andconstruction of a new 5.0 MG ground storage tank and associated high service pump station for theCity. The ground storage reservoir is of a somewhat unique design employing an inner circular tankwall to create two 2.5 mg compartments that can be isolated for maintenance. The high servicepumping system incorporates a jockey pump and five high service pumps coupled with variablefrequence drives (VFDs) to deliver up to 14.1 MGD at 80 psi pressure to the City's water customers.The project also included two degasifiers, a biotracking filter odor control system, chlorine contactchamber, transfer wet well, and transfer pumps. Chemical storage and feed facilities were providedfor sulfuric acid, scale inhibitor, lime solution, carbon dioxide gas, ammonium sulfate, hydrofluosilicicacid, phosphate corrosion inhibitor, and sodium hypochlorite.

Tetra Tech was responsible for the complete design of all of the raw water supply facilities, ROprocess, post treatment processes, storage and pumping facilities, pipelines, structures, electricaland instrumentation, and for coordinating with state and local permitting agencies, seeking permitmodifications, and obtaining construction permits for these facilities. Permits obtained included thebuilding permit, three modifications of the FDEP water construction permit, FDEP construction permitfor the supply wells, modifications of the SWFWMD ERP permit, FDOT right-of-way permit, PinellasCounty right-of-way permit, US Army Corps of Engineers ERP permit, and FDEP Generic permit forthe Discharge of Ground Water from Dewatering Operations.

To reduce the discharge of reclaimedwater to open waters and more fullyutilize their reclaimed water resources,the City of Clearwater is investigatingthe feasibility of replenishing aquifersystems in the City with highly purifiedreclaimed water. In 2009 the Cityauthorized Tetra Tech to evaluate thefeasibility of utilizing advancedtreatment processes for purification ofreclaimed water at a capacity of 3MGD with the objective of replenishinga local groundwater aquifer within theCity.

The initial 2009 feasibility study was followed by a jointly funded feasibility study in 2011 with theSouthwest Florida Water Management District (SWFWMD) as a cooperative funding partner to theCity. This study provided a continuation of previous evaluations, including refinement of theconceptual purification treatment process consisting of the following treatment steps:

• Ultrafiltration

• Reverse Osmosis

• Advanced Oxidation Process

• Membrane Contactors

• Post Treatment Stabilization

This treatment process adopts the multi-barrier processes utilized for other Indirect Potable Reuse(IPR) projects in the United States and abroad, but also added dissolved oxygen removal to minimizeany potential for arsenic mobilization in the receiving groundwater. Additionally, the feasibility phaseincluded meetings with regulatory agencies and project stakeholders, development of the publicinvolvement process, and updates to cost opinions for construction and operations.

In 2012, the project entered the pilot testing phase of the treatment processes that were conceptuallyoutlined in the previous feasibility studies. The scope of services included the design and one-year operation of an advanced treatment process pilot system for treating reclaimed water.Other services that were provided included administration of the pilot system construction andequipment procurement, permitting, coordination with regulatory agencies, and start-up andtroubleshooting. Services during the one-year operational period included data collection, review ofsystem operations, troubleshooting and recommendations for operational adjustments andmembrane cleanings, water quality sampling and monitoring, emerging constituent challenge testing,and support of the City's public education and information program. The sampling program includeda wide array of water quality parameters including emerging constituents of concern as well astesting for mutagenicity of the reclaimed and purified water. This work will be concluded with thepreparation of a summary report of the purification process pilot system operations.

Following successful completion of the one-year pilot program, Tetra Tech was contracted in 2016 toprovide the final design, permitting and bidding services for the full scale advanced water treatmentfacilities at the City's Northwest Water Reclamation Facility. Design for this 3.0 MGD facility wascompleted in 2017 and a draft permit for the facilities was issued in 2018.

The City of North Miami Beach's water treatmentplant included approximately 15.0 MGD of limesoftening water treatment facilities located at theNorwood-0effler Water Treatment Plant.

In June 2001, Tetra Tech was retained to performpreliminary design, final design, permitting, andconstruction services to expand plant capacity totreat a total of 32.0 MGD with nanofiltration and low-pressure RO technologies. The expanded facilityconsists of 15.0 MGD from existing lime softening

facilities, 9.0 MGD for new nanofiltration facilities, 6.0 MGD from new low-pressure RO facilities, and2.0 MGD of micron filtered raw water blend.

The project was designed to make the City of North Miami Beach independent of the Miami-DadeWater and Sewer Department system, which historically supplied approximately half of their finishedwater. One primary advantage of the program was an improvement in water quality to the City'scustomers. An important part of this facility design was the blending and stabilization of waters fromfive different sources: lime softening effluent, RO permeate, nanofiltration permeate, filtered rawBiscayne aquifer ground water, and filtered raw Floridan aquifer ground water. A water blendingmodel was developed to determine the best combination of sources for each system demand tominimize finished water quality variations in terms of color, hardness, chlorides, and disinfection by-products.

Post treatment facilities were designed to provide the proper conditioning of the treated watersrequired for disinfection, producing a chloramine residual for disinfection by-product control, blendingthe waters together for a uniform quality, adding a phosphate inhibitor for corrosion control andadding sodium hydroxide to the combined flow stream as a final control of the finished water pH andstabilization index (Langelier Index).• Facility improvements included:• Five new Biscayne aquifer wells and four new Floridian aquifer wells• One deep injection well for concentrate disposal• Bulk chemical facilities• High-pressure feed pumps with variable frequency drives

• Energy Recovery Devices• 9 MGD of nanofiltration and 6.0 MGD of LPRO membrane treatment facilities• Degasification and odor control facilities• New operations and process buildings• Associated yard piping, site work, paving, drainage and grading• Electrical and instrumentation facilities• Two new ground storage tanks and new high service pumping facilities• Gravity sludge thickening facilities• Security System

Construction administration services were also provided for this project, including bidding servicesand construction management. Upon project completion, Tetra Tech prepared record drawings andcertified the project complete to the Florida Department of Health and Miami-Dade DERM.

Project Value:$40,000 (study)

The City of Hardinsburg, Kentucky set a long-term goal of supplying every resident ofBreckinridge County with a safe and potabledrinking water supply, and to attract industry tothe County to supply jobs and boost theeconomy of the area. To provide this supply,the City contracted with Tetra Tech to evaluatewater supply and treatment options to expandand improve their existing water system. Anevaluation document was prepared to support aWater CIP for the City.

The City's existing supply included a 1.6 MGDsurface water treatment plant located on the Rough River Reservoir and a countywide transmissionand distribution system serving the residents of Breckinridge County and the Cities of Hardinsburgand Irvington. For several years, the city had been experiencing high levels of formation ofdisinfection I disinfectant by-products (DIDBP) due to the high organic content of the reservoir'swater. Therefore, the study document evaluated expanding and improving the existing surface waterplant to meet water demand and water quality goals, and the construction of a new facility. Thestudy recommended a new groundwater treatment facility.

Tetra Tech was hired to provide pilot testing, preliminary, and final design services for a new 3.3MGD reverse osmosis RO water treatment facility to treat groundwater from the alluvium fields alongthe Ohio River in the northeast part of the county. The proposed groundwater source containedhardness and nitrates, and the pilot test confirmed removal of both of these constituents to complywith water quality standards. The plant was the first RO water treatment plant constructed andowned by a Kentucky municipality, and was designed to be easily expanded for increased capacitiesat minimal cost.

Project Management Plan

Project Administration

Tetra Tech has developed propriety tools to effectively manage its projects. The tools support the Five ProjectManagement Processes identified by the Project Management Institute:1. Initiation - Beginning the project on the correct foot by doing things like developing a good scope of work2. Planning - Developing good project (work) plans to guide the work3. Executing - Completing the work according to the plan4. Controlling - Adjusting the plans and execution to accommodate project and client needs5. Closing - Bringing closure to the project by doing things like confirming the scope has been completed,

ensuring the client is satisfied, and organizing project notes for archiving

Examples of typical processes that are used to manage our client ' s project are:

• A comprehensive work plan prepared and shared with all members of the team.

• Monthly, written progress reports (more frequently during fast-track tasks). The reports include anassessment of how the project is tracking the agreed upon budget and schedule.

• Draft meeting minutes delivered for comment by e-mail within 48 hours of the meeting.

• Project audits by an independent professional to ensure the project is meeting scope and is within budgetand schedule.

Tetra Tech ' s approach to developing sound engineering/construction recommendations and problem resolutionbegins prior to commencing work on the project. Our approach is based on a collaborative, team-baseddecision-making process. The process consists of:• Developing team-shared vision, goals and objectives• Recognizing stakeholder needs, goals, and objectives

• Identifying potential barriers and providing solutions for successful project delivery• Utilizing team-based decision making• Providing project leadership, direction and guidance

This collaborative process results in trust through open, honest, and frequent communication.

Project Goals

One of the first steps is to develop the project goals and defined standards further. The goals consist of budgetand schedule targets, specific performance goals, project features, and, most importantly, what the Citydesires/needs/wants. These goals will guide the process and project features. It is critical to the project successthat these goals are confirmed during the kickoff meeting and that City input is incorporated.

The goals become an underlying theme of the project and delivery of the work. They are communicated tomembers of our team and City representatives alike. Project alternatives are judged against established goals. Atthe conclusion of the project, quality is judged by how well the project goals are achieved.

Project Concept Development

The planning phase of the project establishes and identifies the project goals, team, and lines of communication,budget, schedule, project milestones, construction concerns, and project kick-off. Through proper planning, wewill have a thorough understanding of the project issues and deliverables at the onset of the project, which inturn will enable us to exceed your expectations.

Project Delivery

Tetra Tech's project management procedures are designed to keep the project schedule and budget on track.This is accomplished by holding regularly scheduled meetings to encourage communication among teammembers and key stakeholders.

Project Meetings - Project meetings are held to review progress, budget, and schedule status, and to identifyand discuss any project issues. The meetings are designed to anticipate problems before they occur. At the

44

[m) TETRA TECH

meetings, an honest assessment of progress is presented and compared with planned budget and scheduleestimates. The meetings include updates with appropriate City staff members. During the pre-design phase,meetings will be held more regularly than during the detailed design phase. Ultimately, Tetra Tech, with theagreement of the City, will schedule meetings as required, adjusting the frequency as necessary to ensure heproject remains on schedule.

Management Plan -All Tetra Tech projects, regardless of size, are managed using our in-house ProjectManagement Guidelines and Policies Manual. This manual sets forth procedures for project start-up, tracking,and closure. These procedures are tools that our project managers use to ensure that all project tasks are

properly planned and executed. The guidelines include procedures for project planning, contract execution,project team assignments, project meetings, filing, correspondence, and budget, schedule and quality control aswell as project close-out. By adhering to these procedures, the City will receive a quality project within scheduleand budget.

A detailed work plan will be developed that identifies the specific scope of work, budget, and responsibilities foreach team member. After the project team kick-off meeting, each team member will have a clear understandingof the project scope, schedule, budget, and individual responsibility. Mr. Kinslow will then monitor and controlthe project's schedule, budget, and quality of work, which provides a means to implement the proposed workplan in an efficient and timely manner that meets the City' s expectations.

Project Schedule - Developing a detailed project schedule is essential to overall project success. The Tetra Techteam will develop a Critical Path Method (CPM) schedule consistent with the project time frame and the needsof the City. The schedule will identify baseline for work progress, critical path items, and those tasks that requirework efforts from subconsultants, suppliers, contractors, and/or City personnel. The degree of activity detail willcover the major phases of the project. Developing a comprehensive schedule as part initially allows for a morethorough and complete response, with identification of any assumptions on the part of Tetra Tech and the Citythat require resolution before commencing work on the project. The schedule becomes the road map by whichthe overall success of the project is judged.

Coordination - Frequent and effective communication among team members, City, and other projectstakeholders is a key element in the timely and successful completion of each assignment.

Coordination will be accomplished through regularly scheduled meetings with the following agenda items thatwill be adjusted depending upon the participants:• Project progress and pertinent interim findings• Issues regarding the designated scope of services and deliverables• Problem areas• Planned activities• Coordination of field investigations and agency contacts• Review of work status relative to schedule and budget

All meetings will be documented with written meeting minutes distributed to the attendees and placed in theproject file.

Project Communication

Tetra Tech is committed to fully informing the City's project manager of all day-to-day activities and progress.This is achieved through project correspondence as well as weekly progress reports that allow the City's projectmanager to measure the actual-versus-plan work progress. Central to our project administration is theassignment of an experienced project manager highly qualified in the ROWTPs. Mr. Kinslow will serve as thepoint of contact with the City, which allows the City's project manager to obtain pertinent project informationwithout extra efforts. All assigned team members will report directly to the Mr. Kinslow. A paramountresponsibility for Mr. Kinslow is maintaining effective communication among all team members.

Quality Assurance/Quality Control

Our team clearly understands the importance of making certain that the City receives the highest qualityproduct from Tetra Tech. For each project, a person that is not directly working on the project will oversee theQA/QC team for each milestone and will ensure that all the project goals are met. This program helps confirmdesign concepts at an early stage and prevent change orders.

In addition, in mid-2018 Tetra Tech incorporated a risk management process to supplement the standard QA/QCreview. The risk management process has identified company practice leaders and chief engineers throughoutthe country responsible for different project disciplines. These individuals are made aware of ongoing projectswithin their discipline and are available as an additional resource to the project manager and QA/QC reviewer.

Project Understanding and Approach

Our Commitment to this Facility

The James E. Anderson WTP represents great significance for both the City and Tetra Tech, and to this day wefeel very privileged to have been trusted to have served the City for such a landmark water supply facility. Asone of the largest brackish groundwater facilities in the State of Florida and the United States, we consider thisfacility to be a significant achievement in both advancing the use of RO membrane technology at large scale andin the performance, it has sustained through over a decade of exceptional operations by the City. It is difficult tooverstate the depth of personal investment that our key project staff have in the success of the facility, howeverit is fair to say that our personal level of commitment to serve the City cannot not be matched by any other firm.

Maximizing the City's Current Investment

As the design engineer for all previous membrane installations at the James E. Anderson WTP, our team isknowledgeable of all four phases of membrane start-up at the facility and the unique differences in each ROskid. Using data from the initial start-up as well as current operating data, our suggested project approach willevaluate performance of existing RO skids on an individual basis and develop a membrane replacement planthat will provide the City with a recommended replacement schedule to maximize the remaining life andperformance of their current investment in membrane elements.

Additionally, we understand that the current concern is the increasing total dissolved solids (TDS) or salinity inthe City's existing groundwater supply wells and the potential impact to the treatment plant. Our firm hasrecently completed design assignments that successfully utilized process advancements including energyrecovery technology and other customized configurations of RO treatment units to address these concerns forother facilities. We can bring this expertise to bear for the City and provide a solution using a refined controlprogramming strategy that will address operational demands of the changing supply water and maximize theuseful life of existing mechanical equipment such as pumps, piping, valves, and pressure vessels.

Addressing Impacts from Changing Groundwater Quality

Our team is also familiar with the variability in raw water salinity and can benefit the City through our recentproject experience involving the design of an innovative variable salinity/recovery RO treatment process for theCity of Tarpon Springs, treating supply wells that range from 3,000 to over 17,000 mg/L of total dissolved solids(TDS).

In addition to engineering services, our firm also provides more than two decades of experience and knowledgeof the raw water supply wellfield, having provided hydrogeological services to the City. This will allow us toprovide technical solutions that are seamless throughout the facility from supply to concentrate disposal.

Energy Recovery and Process Optimization

Since implementing energy recovery devices (ERDs) in the form of hydraulic turbochargers at the James E.Anderson WTP in 2005, our design team has used this technology as a standard design feature for numerousmembrane facilities, with nearly 15 years and approaching 50.0 iviGD of design experience. In addition to

46

TETRA TECH

providing energy savings, our designs have leveraged the use of ERDs to treat high salinity water sources,achieve high recovery rates in brackish water systems, and optimize RO membrane life and performancethrough improved flux balancing.

Understanding of Design Intent and Prior Construction History

Due to our institutional knowledge of the JEA WTP, our firm is in a unique position to more quickly andeffectively prescribe the appropriate corrective actions to meet the City's goals. In discussions with the City'sstaff responsible for plant operations over the last 10 years of operation (since the final expansion was placed

into operation in 2008), we have maintained a record of issues experienced at the plant and potential rootcauses that may link to the plant construction or the equipment that was supplied. We also have retainedrecords from start-up testing that will be an invaluable resource for adjusting control system programming forany plant optimizations that are controls related. For a large and complex facility such as the JEA RO WTP, thisknowledge will result in the ability to skip past any learning curves and provide faster and more informeddecisions, saving the City both time and money.

Membrane Selection/Optimization

Every plant design project begins with a comprehensive review of membrane selection and incorporatesmultiple levels of optimization as the design progresses. While we have yielded positive results for Owners bothwith and without pilot testing, we agree that pilot testing can offer numerous benefits for both membraneselection and process optimization - so much so that we have included provisions for permanently installed pilottesting units at multiple large capacity membrane systems to facilitate pilot testing to be conducted for longerdurations and to test the long-term effects of pretreatment and other process optimizations.

In the case of the membrane replacement for the James E. Anderson WTP, perhaps the most important reasonto conduct such testing is to validate the membrane projections that are submitted are accurate for the actualperformance that is provided.

Procurement of Replacement Membranes

Our suggested approach to provide the best value to the City would be to competitively bid the membranereplacement services from a shortlist of pre-qualified membrane OEMs and Membrane Manufacturers.Selection criteria for both will include experience with similar supply sources and similarly sized facilities alongwith references from recently completed projects. In addition to the replacement membranes, the MembraneOEMs would include unit pricing for performing rehab and process upgrades to the existing RO treatment units(skids).

Following shortlisting, we will prepare contract documents for competitive bidding of RO membranes to includepilot testing of selected membrane elements and field services for membrane element installation, performancetesting, and treatment skid optimization. Replacement membrane element submittals shall include at aminimum the following information:

• Membrane projections for 0-, 3-, and 5-year operational scenarios

• Membrane performance warranty with permeate water quality goals to be maintained over theinitial 5-year operational period

• Membrane element pricing with guarantee to hold pricing for a minimum of five years to allowscheduled replacement by the City

• Proposed membrane pilot testing plan and schedule

• Proposed membrane replacement plan, schedule, and bill of materials

• Proposed membrane start-up and performance testing plan

Upgrades to Existing RO Treatment Trains (A and B Sides) and Individual RO Skids

Based on discussions with City staff at the plant, potential upgrades that will be considered for the RO treatmentskids may include the following:

RO Skids #1-3 Potential Upgrades (Operational Start-up in 2005)

• Replacement of manually controlled ERD bypass valve with an automated ERD bypass valve

• Convert to insertion venturi flow meters for total permeate flow to match RO skids #4-10

• Replace PVC permeate tubing from pressure vessels with schedule 80 PVC to match RO skids #4-10

Potential Upgrades Applicable to All RO Skids

• Replace aging PVC check valves on total permeate piping (consider alternate materials such as 316stainless steel)

• Replace first stage permeate throttling valves with a process control valve controlled by an electricmotor actuator

• Replace permeate piping (PVC) with stainless steel piping for first stage prior to permeate throttlingvalve

• Replace remainder of RO skid permeate piping (PVC) with stainless steel piping

• Provide permanently installed permeate to waste piping in process piping trenches (to facilitateflushing of new membranes)

• Provide rupture disc or similar means of high pressure relief on skid total permeate piping or oncombined blended permeate header

Other Energy Saving Optimizations

Concentrate Disposal Backpressure

At the time of the initial construction of the JEA ROWTP, the on-site injection well was designed to receive bothRO concentrate as well as disposal flow from other sources off-site. We will evaluate the current operationalprotocols and history of the existing deep injection well and evaluate potential for improved energy recoveryperformance, which is possible from the elimination of specific backflow preventers on the RO concentratepiping prior to discharge to the deep injection well.

Permeate Throttling Pressure

Permeate throttling of the first stage is a feature that balances permeate flux between the first and secondstages, however, this control parameter will typically require small adjustments over time as the membranesage and changes occur in raw water salinity. Our firm has implemented the use of control valves for thisoperation on recent projects, which allows the control system to be automated for adjustments based on eitherpressure or flow set points. A similar optimization could be implemented on existing skids to reduce feedpressure requirements and extend the useful life of existing RO feed pumps.

Firm's Work Plans

Special Concerns or Technology

Tetra Tech has developed novel designs that advance the application of RO treatment for municipal treatmentfacilities. Such applications include high recovery RO configurations that promote optimized performance andprocess control, and variable recovery designs that allow for treatment operations to automatically adjust forswings in feed water salinity. These design innovations are examples of technical tools that may be beneficial toaddressing the membrane replacement and optimization at the James E. Anderson ROWTP.

Knowledge of Local Circumstances

City Staff: Our team for this project consists of the same staff who delivered the initial construction and thenbuild-out of the James E. Anderson ROWTP. We have continued to maintain contact with utility staff sincecompletion of the plant and have provided assistance through providing records or insights into operation and

maintenance matters since that time.

Existing Infrastructure and Equipment Systems: Through continuity in our key project staff, our team hasretained a full and complete knowledge of the existing treatment facilities. As Project Manager, Jarrett Kinslow

worked on all previous phases of construction at the JEA WTP site, beginning with the conceptual andpreliminary design phases and spanning over eight years of direct experience through the start-up and testing ofthe final expansion phase. Our knowledge extends well beyond what is obvious at the surface and includes adetailed understanding of all on-site infrastructure and inner workings of the plant.

Permitting: We are familiar with local permitting offices that are applicable to this project and have successfullypermitted the last expansion phase of the JEA ROWTP through FDEP with the submittal of a preliminary designreport, which allowed expansion design and permitting to be expedited to meet the City's rapid expansiontimeline. Prior to that we were able to successfully work with FDEP to fast track the startup of the 6.0 MGDphase of the JEA ROWTP when the nearby St. Lucie West water supply system experienced an unplanned water

production outage in 2005.

As noted above, approximately 18 months is estimated to complete the project based upon an assumption thatall membrane replacement work would occur as a single event, with a single train taken out of service at anytime. It should be noted that due to the difference in operational age on each of the four (4) phases of capacity

expansion, a more spread out replacement schedule may be preferred by the City.

Schedule for Alternate ApproachAs an alternate to the task structure outlined in the RFQ documents for consideration by the City, by includingmembrane element replacement and RO train modifications into a single set of bid documents, additionalprocess coordination responsibility can be integrated into the contract documents, and pilot testing can beincluded as a final demonstration step for the membrane replacement procurement. This will allow forimproved efficiency in bidding and compressing of timelines for pilot testing, which would be included in theMembrane OEM's scope following initial screening of replacement membrane elements. Membrane projectionsand supporting data from reference installations will be used to select membranes that provide the best value

to the City based on element price, water quality, and pressure requirements (energy use).

As shown above, this alternate bidding approach rolls tasks for pilot testing and interstage boosting

modifications into a single scope of work with the membrane replacement and would reduce the overallschedule by 60 days. This will simplify bidding and provide a savings in engineering support for a single bidpackage instead of multiple bid packages. Additionally, reduced costs are assumed for a reduced duration ofpilot testing, while accomplishing the same end goals of the tasks as outlined in the RFQ documents. Byproviding 60 days of pilot testing for the selected membrane manufacturer instead of an assumed 30 days eachfor three membrane manufacturers, additional process optimization can be conducted at the pilot scale withreduced risk to the full-scale equipment.
