INTRODUCTION The City of Denton (OWNER) intends to conduct a study of its Lake Lewisville Water Treatment Plant to determine improvements necessary to comply with applicable regulatory standards (e.g. drinking water, codes, etc.); customer water quality goals; and operational and facility efficiency objectives. Malcolm Pirnie, Inc. (ENGINEER) will perform professional engineering services to conduct the study (PROJECT). Specific elements defined in the request for proposal and addressed in this scope are as follows: ■ Evaluate disinfection strategy ■ Evaluate taste and odor control ■ Improve chlorine and ammonia facilities for safety and capacity ■ Evaluate filter operations and advise on replacement of underdrains; retrofitting air scour; filter to waste; retrofit to membranes; and similar ■ Evaluate options for correcting hydraulic deficiencies of plant ■ Evaluate sludge removal system ■ Evaluate the negative impact related to current enhanced coagulation strategies ■ Evaluate pH adjustment system ■ Evaluate backwash recycle practices ■ Evaluate plant operations and water quality with respect to current and future regulations ■ Evaluate the reliability and condition of plant facilities and equipment ■ Evaluate source and distribution water quality as appropriate for the treatment process selection II. DETAILED TASK DESCRIPTIONS To address the specific elements of work, ENGINEER will conduct the Study Phase Services for the PROJECT as detailed in the following tasks. The outcome of the study will provide: ■ Recommendations of a process design that meets water quality objectives (regulatory and customer driven) ■ Recommendations for improvements to specific technical issues indicated above ■ Basis of design for facility process components (loading rates, sizing, etc.) to enable subsequent development of plans and specifications for bidding ■ Prioritized implementation plan for the capital program with associated estimated project costs and schedule Task 1 - Project Administration ENGINEER will conduct project management of the work including project planning; preparation and submittal of monthly activity reports, invoices, schedule updates and decision needs to the OWNER; management and coordination of subcontractors; and monitoring and control of schedule. Communication with the OWNER will generally be weekly through phone calls or email, as appropriate with written communication for substantive items. Deliverables: ■ Monthly activity reports, schedule updates and invoices Task 2 - Data Collection ENGINEER will prepare a data request for source water quality, the existing plant facilities and distribution system (as appropriate) including construction drawings, schematics, diagrams, shop drawings, reports, pilot data, pertinent operating records including MORs, chemical use data sheets, water quality test reports, energy records, and related data in order to conduct the study. For water quality data that is not available, ENGINEER will submit a request for analysis by the OWNER on agreed upon parameters (e.g. MIB/geosmin). ENGINEER will also investigate availability of pilot / bench scale data available from other users of the Lake Lewisville source. OWNER will forward material to ENGINEER and ENGINEER will make copies of data the OWNER needs returned. Deliverables: ■ Data request ■ Analysis request, as necessary ■ Graphical results to present water quality trends using available OWNER data Task 3 - Initial Meeting with OWNER ENGINEER will attend a preliminary conference with the OWNER at the OWNER'S offices to discuss the PROJECT. The meeting will include team introductions, discussion of project goals and objectives, identification of deliverables, schedule, and discussion of additional data requirements. Levels and frequency of communications will be established. ENGINEER will prepare an agenda at least 3 working days in advance of the meeting and a summary within 3 working days afterward to document substantive comments. Deliverables: ■ Meeting agenda ■ Meeting summary Task 4 - Site Reconnaissance at Plant On the same day as the initial meeting with the OWNER (Task 2), the ENGINEER will conduct a tour of the plant site, documenting in detail the condition of process components including mixing, flocculation, sedimentation, filtration, and pumping; support facilities including washwater recycle, chemical storage and handling, and electrical and instrumentation systems; and, using our operations specialist, conduct an operations practices analysis. Information will be collected in standard facility templates. Deliverables: ■ Data collection templates ■ Photographs Task 5 - Detailed Assessment of Data and System Information ENGINEER will assimilate and review the data collected from the OWNER'S records (Task 2), initial meeting and the site tour. A description and condition assessment of each facility will be prepared and documented. The information will be documented and incorporated into a draft "Description of Existing Facilities" chapter of the study. In addition, a hydraulic "capacity" assessment using a computer model will be made of each plant facility component to identify hydraulic constraints and capacity of each component. Within 15 working days of completing the operations practice analysis, the assessment will be documented in a separate memorandum to the OWNER. It will contain initial recommendations that plant staff can readily implement to optimize operations without significant capital investment. It will also contain a brief discussion (based on discussions with staff and the data review) on distribution system aspects that impacts water quality (e.g. blending, tank operations, etc). Deliverables: ■ "Description of Existing Facilities" chapter of the report ■ Operations assessment memorandum ■ Hydraulic "capacity" assessment Task 6 - Develop Criticality Ranking, Establish Water Quality Goals and Conduct Workshop No. 1 The ENGINEER and OWNER will meet in Workshop No. 1 at ENGINEER'S office to conduct the criticality assessment of the existing plant components and to develop the water quality goals (regulatory and city/customer driven) that will serve as the basis for developing treatment alternatives and facility improvements. Immediately prior to Workshop No. 1, the ENGINEER will develop and submit to the OWNER the initial criticality factors and ranking of each existing facility component (evaluated as part of Tasks 4 and 5). It will contain a proposed numerical rating system and the initial values applied to each component for initially rating its condition. Then, in the workshop using a pair wise comparison matrix, the criticality of each component to meeting water quality goals, safety standards or to sustain reliable operations of the plant will be determined to rank the importance and priority of any needed improvement. The results of this analysis will be used to develop alternatives and associated planning level costs. The ENGINEER will facilitate the pair wise comparison analysis. ENGINEER will prepare an agenda and the initial pairwise facility matrix with initial ratings at least 3 working days in advance of the workshop and a summary within 3 working days afterward to document substantive comments. Deliverables: ■ Meeting agenda and initial pairwise matrix for rating existing facility components prior to workshop ■ Meeting summary documenting water quality goals and the results of the criticality analysis Task 7 - Develop Alternatives and Conduct Workshop No. 2 In advance of Workshop No. 2, the ENGINEER will prepare a listing of multiple treatment alternatives (ten to fifteen) that could potentially meet the water quality objectives and address facility deficiencies based on its experience and prior OWNER input. These initial alternatives could range from simple process modifications / enhancements to the existing conventional plant all the way to integration of new processes such as ozone, ultraviolet light irradiation, granular activated carbon adsorption, membrane filtration, etc. Capital and operational costs for the candidate alternatives will be based on USEPA cost curves and historical data (e.g. cost per 1,000 gallons) for purposes of comparing the relative costs of each only and not with the intention of developing budgeting at the screening level. Then, the ENGINEER will conduct the Workshop at the ENGINEER'S office to discuss the merits of the initial alternatives and conduct an initial screening using standard screening criteria developed by the ENGINEER and a software package (Decision Criterium Plus). The intent of the workshop is to obtain significant OWNER input on the candidate alternatives then screen down to the 3 to 4 most viable treatment alternatives for final review and assessment. In addition, as part of the workshop, ENGINEER will solicit the OWNER'S input on rating factors and importance weights to use for the detailed alternatives analysis (Task 8 below). ENGINEER will prepare an agenda and preliminary alternatives at least 3 working days in advance of the workshop and a summary within 3 working days afterward to document substantive comments. Deliverables: ■ Meeting agenda and factors for the initial screening of alternatives in advance of workshop ■ Meeting summary documenting results of the screenings and the factors and weights to use for the final alternatives evaluation Task 8 - Conduct Detailed Alternatives Assessment and Workshop No. 3 In assessing the final 3 to 4 treatment process alternatives screened to under Workshop No. 2, it is anticipated that the ENGINEER will assess both economic and non -economic factors (developed in Task 7). Costs analysis will be developed in three components - capital, operations and life -cycle. Capital costs will be based on the detailed definition of the candidate alternatives and priced in costs sheets using historical data from Malcolm Pirnie bid projects bid in the Dallas/Fort Worth area plus a contingency of up to 20%, to account for variability of risk and detail available. Operational costs will be developed using the OWNER'S anticipated costs for labor, chemicals, power, and related. Where appropriate, an inflation factor may be assigned to each operational cost to determine the relative impact on the overall life -cycle cost of each alternative. Life -cycle costs will be based on the prevailing interest rates, expected to be in the range of 4 to 6%. Using Criterium Decision Plus software, the ENGINEER will conduct a detailed analysis of the 3 to 4 candidate alternatives and place initial ratings against each factor. ENGINEER will forward the analysis in a technical memorandum form to the OWNER for initial review. Within two weeks of the submittal, ENGINEER will meet with the OWNER at the ENGINEER'S office to receive comments on the analysis. From this review, it is expected the ENGINEER will proceed with finalizing the report development. Deliverables: ■ Meeting agenda and draft alternatives analysis ■ Meeting summary documenting results of the final alternatives analysis Task 9 - Prepare Study Report / Design Basis and Final Meeting ENGINEER will prepare a draft study report and design basis then revise the document to final form. To facilitate timely review and maximize OWNER input, it is expected that the ENGINEER will submit draft chapters for review by the OWNER during the course of the PROJECT (e.g. Description of Existing Facilities - Task 2; Facilities Assessment - Task 5; Alternatives Analysis - Tasks 7 and 8; etc.). The report contents will generally cover the following: ■ Executive Summary ■ Project Background, Data and Information ■ Description of Existing Facilities ■ Regulatory Assessment ■ Treated Water Ouality Goals ■ Treatment Technology Descriptions ■ Treatment Alternatives Evaluation ■ Recommended Facility Improvements ■ Implementation Plan and Costs ■ Design Basis Summary ■ Appendices - Facility condition assessments - Treatment operations assessment - Cost information - Equipment data sheets as appropriate This document is assumed as a Preliminary Engineering Report level of detail, defining the work in conceptual level adequate for development of drawings and specifications. Ten copies of each draft document will be submitted followed by up to thirty copies for final record. The ENGINEER anticipates a final review meeting with the OWNER at the ENGINEER'S offices to discuss and receive final comments on the compiled draft document. Review comments will be addressed and the final copies submitted for record. This report will serve as the basis of subsequent design services. Deliverables: ■ Draft report - up to 10 copies ■ Final report - up to 30 copies ■ Final meeting summary Task 10 - Assistance for Presentations to Governing Authorities ENGINEER will assist the OWNER for preparing for and attending up to two meetings with governing authorities (City council or Utility Board). Assistance includes preparation of presentation materials and handouts. Deliverables: ■ Powerpoint or similar presentations in electronic form ■ Handouts - 30 copies per meeting III.

Denton Benefits Because Our Fresh "Source to Tap" Vision Will Deliver the Best Overall Upgrade to Cost -Effectively Improve -Water Quality Malcolm Pirnie has long been aware of, and intensely preparing for, the City of Denton's (City) RFP relating to the Lake Lewisville Water Treatment Plant Upgrade. During this time we have been doing our homework in order to understand the project goals, recognize critical issues and discern the City's articulated and unarticulated needs. Our staff has conducted multiple site visits to the facility and met with City staff at all levels to develop our understanding of what is important. Based on what we found and heard, resolving the following critical challenges will be essential for success. We need to: ■ Develop the most appropriate treatment process that improves disinfection for current and impending regulations, addresses taste and odor, increases organics reduction, and minimizes impacts to the distribution system and customers, all in a cost-effective manner. (Refer to Section D, Technical Items 1, 2, 7, 9 and 10) ■ Design safe and reliable chlorine and ammonia facilities that meet current codes and safety standards. (Refer to Section D, Technical Item 3) completely meet the City's needs within budget. ■ Modernize and upgrade flocculation, sedimentation, filtration and residuals / recycle processes to improve functionality, extend service life, and reduce operation and maintenance requirements. (Refer to Technical Items 4, 6, and 11) ■ Resolve operation and maintenance issues related to caustic feed, hydraulic impediments, sludge draining by using a balance of creative concepts, automation, and operations. (Refer to Technical Items 5, 6, and B) To meet these critical challenges, we have 'assembled an outstanding team and created an approach that meets the specific requirement's of :the RFP. and provides -strong "value added" benefits; By selecting our team, we can offer-Ahe: `City: ■ A Strong, Locally Committed Delivery Team That Promises to Meet the Schedule. We can contractually commit all of our key team members to this project. In addition, we offer to include liquidated damages in the engineering contract for schedule delays for which we are responsible. ■ A "Source to Tap" Approach That Provides the Best Total Solution. For example, to ensure we address source issues, we have engaged Sam Atkinson, PhD of the University of North Texas to advise our team on Lake Lewisville issues. A Time and Cost -Saving Strategy for Piloting and Plant Optimization. Should piloting type data be required, we have an approach that relies on prior piloting efforts of Lake Lewisville water if ozone is considered or concurrent piloting / preliminary engineering timeline for membranes to eliminate schedule delays. We also propose optimization of the existing plant through full-scale tests. ■ A Proven Process Selection Approach. Our approach relies on a workshop -based process where, collectively, we would define water quality goals, establish candidate processes that can meet these goals, followed by a matrix evaluation process, using Criterium Decision Plus Software, that objectively ranks alternatives using cost and non -cost factors with assigned importance weights to each. Our approach results in defensible solutions that completely meet the City's goals. ■ Innovative Solutions For Flocculation That Substantially Reduce Maintenance While Improving Coagulation and Hydraulics. Considering concepts such as hydraulic baffled flocculation can eliminate the need for energy and maintenance intensive flocculators while improving coagulation performance and reducing hydraulic restrictions. Low Cost Solutions to Sludge Settling Proven Through Computational Fluid Dynamic Modeling. Simple modeling of the sedimentation basins ensures that we can evaluate the benefits of low capital cost solutions, such as baffling, to improve sludge settling within the first zone of the basins. This allows us to reduce the frequent need to drain and clean the basins. A Low -Cost and Low -Maintenance Solution to Calcium Carbonate Plating Using a Caustic Mix Chamber. Installing a low cost injection chamber concept and introducing mixing can significantly resolve the calcium carbonate plating in the pipes and occasional turbidity spikes from caustic. A Risk / Consequence Prioritized Approach To Assess and Rank Necessary Improvements That Meet the City's Financial Goals. We have a proven approach that methodically assesses, ranks, and orders potential improvements in a prioritized manner. The City can integrate this approach into the capital program and use it for assessing impacts to rates. A Proactive Approach Toward Safeguarding Distribution System Water Quality During Construction And With New Process Changes. We can help the City to proactively manage potential disruptions to water quality caused by construction and the introduction of new process changes. This is accomplished through a well - planned startup protocol that includes contingency procedures to anticipate potential issues. A Construction and Operations Perspective To Complement The Engineering Aspects Of The Design. Integrating construction and operations experience into the design will maximize quality, constructability, and operability of the design. Bringing this perspective to our team are our operations specialist Jim DeWolfe, and construction engineer Fred Johnston. ■ A Cost -Containment Approach That Delivers A Facility Meeting All Project Goals Within Budget. Past successes with other large water projects proves our plan enables us to proactively manage cost growth at each stage of the project to prioritize the design. This will enable the City to make decisions that keep it within the overall budget. Section D contains detailed discussion on these value-added aspects of our approach, including the steps we will employ in developing the best solutions for the City. Firm Personnel's Availability Through our Dallas office, we have successfully Implemented major water treatment plant planning, design and construction efforts, and we ,are available and eager to help the City do the same. In the previous three years, our proposed local delivery team has completed the process evaluation and design of a $31M Water Treatment Plant Expansion & Upgrade for the Trinity River Authority, an $IBM new Membrane Water Treatment Plant for the Guadalupe Blanco River Authority and a $SM Expansion and Upgrade for the City of Lewisville. Our team has experience working together and furthermore has the necessary availability to meet the schedules as further discussed in Section D - Approach. "...on the TCWSP project, the work was very .thorough and completed on time ... very responsive to the Authority's needs."

RELEVANT ExPERIENCE AND CAPABILITIES Completing the Project on Time and Within Budget Our Implementation Strategy and Cost Containment Approach Ensures Completion of the Project on Time and Budget Malcolm Pirnie has a 110-Year history of completing water treatment plant projects on time and within the engineering and construction budgets. Over that period, we have developed efficient processes, experience and reputation to deliver projects. For example: ■ In Section D, under "Project Schedule and Deliverables" on page 11, we have committed to completing the preliminary design report by May 2006 as evidenced by our proposal to include liquidated damages if our actions delay the schedule. For the Fort Worth Process Assessment and Trinity River Authority Water Plant Improvements projects, which involved piloting and detailed assessments, we delivered those projects on time. In Section D, under "Technical Approach" on page 23 we describe a detailed cost -containment approach that will deliver the Lake Lewisville Water Treatment Plant Upgrade on budget. That section contains several examples of our recent history of successfully completing projects within budget. Disinfection Evaluation Strategies & Regulatory Constraints Malcolm Pirnie is at the leading edge of disinfection technologies and the regulatory environment. This is proven by the fact we have been involved in dozens of AWWARF studies and the preparation of USEPA technology documents. For example, Malcolm Pirnie prepared the USEPA Technology and Cost documents for the Stage 2 D/DBP and LT-2 Rules and Guidance Documents for the initial distribution system evaluation (IDSE), membranes and UV disinfection. present and evaluate alternative technologies. We propose multiple workshops with Denton management, engineering and operations staff along with key members of the project team. The first workshop would define the water quality objectives, present all the water process technologies, and compare their benefits to meeting current and future regulations. The second workshop would consider the cost, operations, maintenance, construction schedule, water quality, process reliability and flexibility of the technologies to meet the City of Denton's goals. We have successfully used this identical approach on all of the listed projects (TRA, Lewisville, GBRA, etc.). The approach steps and decision software we use is described in detail on page 12 of Section D. How Rehab Project Issues are Evaluated & Prioritized Our Conditions Assessment and Risk F ,Consequence Approach Identifiesthen prioritizes ,the Right Upqrades to Ensure Reliability of the 'Treatment Process _ A plant rehabilitation and upgrade project must recognize the previous capital investments and value Over the Last 5 Years, Our Malcolm Pirnie Dallas Office has Completed Regulatory Assessments, Process Selections, and Designs for Water Plants Totaling over 0.6 billion gallons per day Capacity. of the existing facilities. Our first objective would be to select the right process meeting the City's water quality objectives then assess the impact it would impose on the existing infrastructure to achieve its integration. After we collectively identify the required upgrades, we would categorize them as to the need and benefit. Under Section D, "Technical Approach Technical Issue #11", we present a step-by-step risk / consequence approach that methodically identifies and prioritizes all upgrades based on their critical nature to the process. With this, we can accurately identify the higher priority needs that must be included to achieve a reliable treatment process. We then follow these with a prioritized listing of other noncritical upgrades we could slate for future projects as part of the City's capital improvements program. Capability of Local Office Our water process team members work closely with Section B details the size and professional staff USEPA and TCEO to understand and shape future disciplines of Malcolm Pirnie's local and national regulations. Mike MacPhee has performed many staff, and the local staff of our subconsultant team. water process evaluations throughout the nation and The proposed evaluation and design team is local, has developed effective communication skills to with the exception of our national experts, Mr. MacPhee and Mr. DeWolfe and the technology panel. The local design team has successfully completed the evaluation and upgrade designs of various water facilities as described later. Relevant Project Experience The appendix includes detailed descriptions of the following projects that demonstrate our teams experience and capabilities to complete the Denton Lake Lewisville Water Treatment Plant Upgrades.

APPROACH Team Organization and Communication Approach (Clear Lines of Responsibility and Delineation of Communication Channels Ensures the City's ;Needs are Understood and Incorporated by the ,Team For a project to be successful, Malcolm Pirnie knows the critical importance of effective communication (both external and internal) and its impacts on project efficiency and quality. We accomplish this by clearly defining roles and responsibilities of key team members and the proper communication protocols (verbal and written). These features are inherent in our team structure, which is as follows: Our team has a primary contact with the City, through an experienced project manager (Robert McCollum) leading the "right" delivery team to ensure the project meets the City's budget, schedule and deliverable requirements; ■ A client service manager (Randy McIntyre) who is independent of the delivery team and serves as an advocate to the City, to assure the City that it's expectations are heard by the team and seriously considered in developing the best total solution(s); and ■ With a sub -team of highly experienced technical specialists and quality assurance consultants that are experts in their field, and that start "Day One" to ensure our team considers the proper array of leading edge solutions with demonstrated performance history. ■ With specialized subconsultants that deliver value to the project in their area of expertise. We select firms with whom we have a long and successful track -record and where their work products can be clearly delineated. The graphic on this page depicts the overall communication chain that our team will follow. Our project manager and team have at their disposal effective tools and processes to ensure our communication is focused, timely and effective. We do this using: ■ Weekly (or more often as needed), communications between Malcolm Pirnie and City Project Manager to discuss progress and issues; ■ Weekly team coordination meetings with a discussion of issues and update of the action list to ensure all items are being appropriately addressed; ■ Submission of a monthly activity report to the City communicating the team's activities during the preceding month, and including a preview of activities for the upcoming month. We will dedicate a special section of the report to documenting major decisions and decisions that we need from Denton to keep the project on course. ■ Bi-weekly updates of the schedule, budget, and action lists that is distributed to the team. ■ In-depth involvement in a rigorous quality program and stop sessions (discussed in more detail in Section E) that ensures the documents are high quality, coordinated, and that the right solutions are employed. Section B illustrates in detail the organizational structure of the project with identified technical 9oMt G. H[Collum nn,a� rae,r�e e .ar s .v a.. roles and responsibilities. The following chart further defines the day-to-day communication and implementation responsibilities of each key member Percentage Commitment of Key Team Members Malcolm Pirnie promises to deliver the team we Propose; consequently, we are prepared to bind their Involvement in the project through contract ',terms. The following chart depicts members's approximate average level of involvement in the project over each phase including their availability to commit to this project. Our team has the availability to commit to Denton Except for our key national water quality experts, we will execute the project using Dallas staff. Advisability of Pilot Work and Schedule Impacts !Capitalizingon Previous Pilot and Full -Scale Data Denton Can Save Time and Money while :Yielding 'the Best Information The piloting of candidate treatment schemes and hydraulic loading rates to simulate full-scale performance can achieve multiple benefits. These include: 3. Optimization of existing and new treatment unit performance to aid in increasing water quality at optimal operating cost; and 4. A demonstration of reliable and credible results needed to receive regulatory approval of the process of choice (i.e. membranes). In a conventional approach, obtaining these benefits comes at the expense of longer project duration (upwards of a year) and increased up front costs to build and operate a pilot facility. Even with these impacts, it is Malcolm Pirnie's experience that piloting is beneficial and pays for itself through the "right sizing" aspect alone because an optimally sized facility can substantially offset piloting costs. In the case of ozone and filtration rates, we can achieve many of these same benefits without spending the additional money or time for piloting. Malcolm Pirnie proposes an approach that will capitalize on previous work by other users of Lake Lewisville water or possibly the Ray Roberts plant. For example, Dallas Water Utilities (largest user of Lake Lewisville water), conducted pilot studies for their Elm Fork plant to assess coagulation processes, and the use of ozone and various high rate filtration options. Malcolm Pirnie successfully used this identical data on behalf of the City of Lewisville at their C.R. Feaster plant to achieve approval from TCEO for increased filter loading rates. This saved Lewisville considerable time and money and resulted in a very cost-effective expansion without the need to add more basins and filters. Using data from plants operating on Lake Lewisville water can save piloting cost while yielding needed data. 1. Evaluating candidate process(es) for Now that the Elm Fork plant and Upper Trinity plants effectiveness in meeting customer and have had ozone in operation for several years, we regulatory driven water quality objectives; can obtain, with their permission, available historical 2. Reduced capital costs since it obtains operating data to optimize sizing of ozone (if performance data for a selected process to selected) at Denton. A second possibility is to enable "right sizing" of facility components; conduct full-scale performance testing in partnership with Dallas to obtain the additional pertinent information including taste and odor reduction, bromate and disinfection by-products formation, turbidity reduction, impact on filtration, etc. We can conduct this parallel with a design and not affect the overall schedule. If membranes become the technology of choice, we can perform pilot testing simultaneously with preliminary design. The pilot testing would (1) confirm the design criteria (flux, clean -in -place interval), and (2) short-list membrane suppliers that meet the performance requirements. Concurrent pilot testing with preliminary design would keep the project on schedule. It is our experience that some membrane suppliers would donate their pilot systems for testing, thus we could save some money. Project Schedule and Deliverables To demonstrate Malcolm Pirnie's commitment to ;Denton, we propose to include liquidated damages 'in the engineering agreement for schedule delays :for which we are responsible. The RFP stipulates completion of the preliminary design report by mid -May 2006, assuming an award in late January, 2006. This schedule is reasonable and our team can accomplish the tasks within this timeline. In particular, with our approach of relying on earlier Lake Lewisville pilot and full-scale plant data for ozone or concurrent design with membranes, we are very confident our team can develop the best solution for Denton by mid -May 2006 without the need to extend the schedule for piloting. The attached graphic (11 x 17 foldout) depicts the project schedule by phase with the associated milestones, meetings with numerous input points by the City, and deliverables. Overall Project _Implementation Approach A Source to Tap Vision Results in the Best 'Overall Upgrade that will Cost -Effectively [Improve Water Quality OBJECTIVES AND CRITICAL SUCCESS FACTORS FOR THE PRELIMINARY DESIGN From our understanding of the work through multiple site visits and meetings with Denton staff, we believe the overall pertinent considerations and challenges that will determine the technical success of this project include the following: ■ Integration of source related aspects into the process selection. We have included Sam Atkinson, PhD of the University of North Texas to bring that balance. ■ Selection of reliable and cost-effective upgrades/ Process modifications that improve operational efficiency and meet current water quality objectives with flexibility to respond to future changes. ■ An approach that enables maximum utilization of existing infrastructure and consideration of cost saving concepts to contain capital and operations and maintenance costs. ■ Integration of operations perspective to assure we implement new processes during construction in a well -planned manner, thus avoiding service disruptions and water quality excursions to the customers. As the project team and the City collaborate and determine the best overall solution for the Lake Lewisville plant, it is important to keep an overall system vision at the forefront to ensure a completely successful project. With this approach, Denton can be assured the right improvements will be selected that effectively treat the water to the regulatory and customers standards at optimal cost. This includes how we would manage water quality and quantity changes even during construction and after the facility start up. Malcolm Pirnie has also established a methodology for selecting the best overall process design. The major steps of this process are shown in the flowchart on the following page. The benefits of our approach are: ■ Our collaborative workshop approach ensures that we clearly delineate the City's needs and place them at the forefront of each alternative we review. ■ By using our panel of industry recognized experts (Section E) in ozone, membranes, UV, disinfection and coagulation, we provide a thorough consideration of relevant technologies to solve the real issues. ■ our approach forges a prioritized implementation plan that matches the City funding limitations and addresses immediate water quality and facility concerns (Technical Issue 11). ■ Our balanced matrix approach using Criterium Decision Plus Software effectively weights economic and non -economic factors for the best total solution. I { ; rr Our evaluation process provides a properly balanced assessment of candidate treatment alternatives. ;We have successfully. used this Identical^approach Ion projects for the Trinity River Authority,. 'Guadalupe Blanco River. Authority, City of Fort 'Worth, and Bonham. Technical Approach We have formatted the following section according to the technical issues identified in the RFP. For purposes of discussion, we have arranged the topics to address two main areas - process evaluations and rehabilitation / upgrades. To present how our team will address each technical issue, we offer preliminary, thought -provoking concepts for consideration that lead to the previously stated critical success factors. In addition, based on what we have learned from our multiple site visits and meetings with City staff, we offer discussion on other aspects of the project where our team can provide value-added solutions. PROCESS EVALUATIONS Technical Issues #1, 2, 7, 9 and 10 - Disinfection, Taste and Odor, Enhanced Coagulation, Regulations / Water Quality With respect to process design, our team will consider all key factors influencing process selection identified from this RFP and from our workshop sessions. Below we offer a snapshot of potential concepts that could meet many of the water quality issues and goal already discussed with the City. Background The City operates two Water Treatment Plants: the Lake Lewisville (LLWTP) and Lake Ray Roberts RRWTP. The LLWTP is a conventional treatment plant with a nominal capacity of 30 mgd. The initial phase of LLWTP was completed in 4957. The RRWTP is an intermediate ozonation plant, which the City started in 2003. The challenges faced with the treatment process are: ■ Maintaining consistent 35% reduction of TOC for satisfying regulations; ■ Potential additional requirements for complying with Cryptosporidium inactivation; ■ Proactive taste and odor control similar to RRWTP. ■ Reducing DBP's to position for compliance with Stage 2 D/DBP Rule; ■ Compatibility of waters between the RRWTP and LLWTP within the distribution system; ■ Some of the process units could use upgrading to optimize their performance (i.e. better mixing of coagulants, enhanced settling in the basins to simplify sludge management and maintenance, filter to waste for filters, etc). Regulatory Update We expect that EPA will finalize the Stage 2 Disinfectants and Disinfection By -Products (D/DBP) and Long Term-2 (LT-2) Rules by January 2006. The Stage 2 D/DBP Rule requires compliance at each monitoring site in the distribution system on a locational running annual average (LRAA) basis as opposed to the overall system running annual average (RAA). The Stage 2 D/DBP Rule will be implemented in two phases. Water systems will have 3 years (2008/2009) to comply with Phase I of the Rule and 6 years (201112012) to comply with Phase II of the Rule. According to Phase I of the Stage 2 D/DBP Rule, the maximum contaminant levels (MCL) for total trihalomethanes (TTHM) and haloacetic acids (HAA5) will be 120 micrograms per liter (pg/L) and 100 pg/L, respectively. In Phase II, the MCLs for TTHM and HAA5 would reduce to 80 pg/L and 60 pg/L, respectively. From data we have reviewed, the historical distribution system TTHM and HAAS were as high as 160 pg/L and 45 pg/L, respectively, thus current THM levels would be problematic. The LT-2 Rule requires source water monitoring of Cryptosporidium. We anticipate that the LLWTP raw water would classify under Bin 1 for LT2ESWTR and therefore may not require any chemical inactivation of Cryptosporidium, beyond filtration. If future monitoring shows the raw water Cryptosporidium concentrations were increasing beyond 0.075 oocysts/L then the water would be classified in higher bin than Bin 1. The higher bin classification will require greater inactivation or removal of Cryptosporidium. Malcolm Pirnie prepared the EPA Technology.and 1Cost documents for the Stage 2D/DBP and LT-2 Rules. Malcolm Pirnie also prepared the Guidance Documents for the initial distribution. system !evaluation (IDSE), membrane filtration and UY disinfection. This first hand involvement provides our team the unparalleled understanding of the upcoming rule requirements and implementation issues. The Malcolm Pirnie team will consider the upcoming regulations including Stage 2 D/DBP and LT-2 Rules in evaluating the process enhancements We Would Craft Candidate Alternatives to Meet the City's Water Duality Goals screening process to assess final candidate alternatives. Described below are initial concepts our team has developed to target the water quality issues of concern to Denton. These are illustrative and it would be important that we obtain the City's input under the actual project beforehand to ensure we provide options that completely meet its needs. Alternative 1: Conventional Treatment with UV In candidate alternative 1, we would enhance coagulation process performance in terms of coagulant and acid addition. Optimizing enhanced coagulation would reduce the (1) O&M costs for chemical addition (2) impact of chemicals on the concrete and internals and (3) possibly reduce solids production through evaluation of different coagulants. Optimizing the enhanced coagulation process can involve improving mixing conditions with new mechanical mixing combined with changes to coagulant/acid dosages. PAC Cli•---� NH, A'nrhJSand 1 UV Na0H Malcolm Pirnie team members have helped several utilities (TRA, GBRA, Canyon Lake WSC, the Cities of Lewisville, Glendale, Phoenix, and Scottsdale) with optimizing their enhanced coagulation practices for total organic carbon (TOC) and turbidity removal. We would consider the lessons learned from these utilities to help the LLWTP staff improve the performance of coagulation/flocculation process. UV on each filter or in vault on site Rapid Mixing Using our implementation approach, previously = described, we would first identify water quality goals Alternative 1: Conventional Plant with UV followed by an identification of all potential candidate alternatives. At this point, we would use a The plant would continue to add chlorine to the settled water flumes and provide future UV disinfection as an additional barrier to the microbial pathogens. The current taste and odor removal approach would continue using PAC addition. No pilot testing would be necessary for implementing this alternative. We present hydraulic considerations in Technical Issue 5. Benefits of this Alternative ■ No piloting required. ■ More budgeted funds would be available to use for overall upgrades rather than process additions. ■ Improved effectiveness of enhanced coagulation with new mixing and chemical optimization. ■ Install UV now or in the future to address Cryptosporidium, should City fall in a higher bin classification in rules. Alternative 27 Ozone/Biofiltration In candidate alternative 2, the plant would inject a small ozone (0.5 mg/L) dose to the raw water using sidestream ozonation (to a recycle stream) then provide intermediate ozonation in new contact chambers to the settled water. To foster biological active filtration we would consider replacing the anthracite / sand media with the deep -bed GAC media. The point of chlorine injection would move downstream of GAC to enable biological filtration. It would be important to assess viability of chlorine free backwash so biological activity is not impacted from washing. Clz NH3 Opt. EC 03 GAC NaOH By using GAC filter media, PAC addition for T&O control could be minimized or discontinued. With intermediate ozone, ozone could serve as the primary disinfectant then we would convert chlorine and ammonia for residual maintenance purposes. Consideration for hydrogen peroxide addition would provide added flexibility to quench ozone before the filters or provide the added benefit of considerably increasing T&O reduction. The Malcolm Pirnie team would evaluate the existing disinfection practices and identify the most optimal locations to add chlorine and ammonia for the rehabilitated LLWTP. The evaluation will recommend a disinfection strategy that is most appropriate for the upgraded plant. Implementing GAC would likely require replacing the underdrains, modifying troughs height, including provisions for air scouring and filter -to -waste cycles, and adding piping/valving to convey GAC in and out of the filters. The piping/ valving for GAC conveyance can be located outside the filter building; so the GAC trucks could locate along side of the building and connect to the media conveyance system. With respect to GAC, bench -scale testing of GAC would assist with identifying the benefits of adsorption, but would not provide information on biological filtration. However, Malcolm Pirnie team members have information on ozone/biofiltration from more than 10 WTPs that would be available to design the retrofit for GAC in the existing filter boxes. Benefits of this Alternative ■ No piloting required using the approach we discussed earlier in this section. ■ Applying low doses of ozone to the raw water using the side stream approach would reduce the capital cost for contactors. Raw water ozonation would assist in enhancing floc formation and TOC removal by enhanced coagulation. ■ Improved effectiveness of enhanced coagulation with new mixing and chemical optimization. ■ Ozone addition coupled with GAC filters provides strong barrier for taste and odor and to man - introduced and emerging contaminants (endocrine disruptors, pharmaceutically active compounds, etc.). ■ Biological GAC would improve DBP precursor removal. ■ The water produced under this alternative would be somewhat similar to the water produced by RRWTP; which will reduce the distribution systems impacts from the addition of a new process at LLWTP. Alternative 3: Post Filter GAC with UV In concept alternative 3, we would add post -filter GAC to remove T&O-causing compounds and DBP precursors. The City could construct the post -filter GAC in phases over several years to match budget constraints. Treating a portion of the water through the GAC contactors and mixing with the remaining waters would still provide additional benefit in terms of T&O control and DBP precursor removal. Provisions would be included for UV addition in the future for Cryptosporidium disinfection if needed. The team would evaluate the physical location of the GAC post -filter contactors at the site with respect to hydraulics and intermediate pumping. Some of the issues that were discussed earlier for other alternatives (e.g., moving point of chlorination) would be applicable for this concept. Ch NH, Opl. EC AntdJSanC; GAC UV 77 '--------"----- NaOH Pilot testing is not required for the post -filter GAC. Bench -scale testing using rapid small-scale column tests (RSSCT) would provide the necessary information for design. Malcolm Pirnie has relationships with universities that could perform RSSCTs, if this alternative is chosen for implementation. Benefits of this Alternative ■ No piloting required with this concept. ■ Improved effectiveness of enhanced coagulation with new mixing and chemical optimization. ■ The post -filter GAC would improve T&O, DBP precursor removal, and serve as an additional barrier to emerging and man -introduced contaminants. ■ Install UV now or in the future to address Cryptosporidium, should City go to higher bin classification in rules. Alternative 4: Membrane Filtration Membrane filtration is becoming a widely accepted choice for filtration. A number of new and existing plants are presently considering low-pressure microfiltration (MF) or ultrafiltration (UF) membranes. For LLWTP, submerged membrane filtration could be a viable alternative for consideration. The submerged membranes could be retrofitted into the existing filter boxes or in the aft section of the sedimentation basins. The membrane retrofit could be staged in phases. PAC Clx NHx Opt. EC MFIUF -------� NaOH In the recent past, the cost for membrane filtration has fallen and is becoming a cost competitive alternative to conventional processes. Membrane filtration provides an absolute barrier to particulates (turbidity) and microbial contaminants (Cryptosporidium, Giardia, viruses). Adding PAC and coagulant in concert with membranes would remove appreciable T&O causing compounds and DBP precursors. Membrane filtration has a compact footprint and provides an opportunity to expand the plant in the future, if necessary, by adding more units and making hydraulics improvements. Malcolm Pirnie's team has assisted several utilities across the country with procuring membranes. Malcolm Pirnie would perform a rigorous evaluation of hydraulics and life -cycle costs for membranes and compare it with the other alternatives. Benefits of this Alternative ■ Concurrent piloting during the predesign - no schedule impact. ■ Improved effectiveness of enhanced coagulation with new mixing and chemical optimization; ■ Submerged membranes would facilitate the opportunity to expand the plant in the future; ■ Using PAC and coagulant, the City would achieve good taste and odor control; ■ Membranes provide a positive barrier for pathogens and credit toward Cryptosporidium removal. Alternative 5: Membrane Filtration with Post -Membrane GAC ■ Submerged membranes would facilitate the opportunity to expand the plant in the future. ■ The post -filter GAC would improve T&C, DBP precursor removal and serve as an additional barrier to emerging and man -introduced contaminants. ■ Membranes provide a positive barrier for pathogens and credit toward Cryptosporidium removal. With each of these candidate alternatives , they would address each water quality issue differently , thus we will consider the vanabiliq within the evaluation process.

For example, the ammonia feeders are located inside the same building and adjoining room as the chlorine feed equipment and containers; any potential leaks from the chlorine ton containers cannot be contained and scrubbed; and the ammonia bulk tank is exposed to view and unprotected. Additionally, much of the equipment is aged and needs upgrades and/or replacements to reduce maintenance, meet capacity requirements, and optimize performance. With potential changes to the disinfection process with ozone, membranes, or UV for example, we expect that chlorine and ammonia use can decrease by between 25 and 50%, thus serving as a secondary residual disinfectant only. Therefore, there may be opportunity to right -size the equipment at the same time as the overall move toward a safer and secure facility. Approach In the aftermath of vulnerability and security assessments, a trend toward improving not only safety, but also security of gaseous chemical systems is occurring because of the potential widespread impact of catastrophic releases to the surrounding public. Our approach will focus on effective containment of releases and mitigation of off -site impacts with costs sensitivity in mind. City staff has indicated a preference for a facility similar to the Ray Roberts plant. That facility employs a full containment concept for chlorine and ammonia with scrubbing capability. This design approach provides a very high degree of safety and security, but it can come at a significant capital cost. At the Lake Lewisville plant with the investment in existing infrastructure and given Denton's budget limitations, we propose to assess alternatives that balance costs and optimum use of facility with security and safety concerns. In addition, we suggest evaluating the cost -benefits of using liquid chemicals or bulk chlorine storage to reduce chemical costs to that of safety concerns. Three alternatives could include the following: ■ A Ray Roberts design (full containment and scrubbing). The cost could be in the range of $4.5 to $5.5M. ■ A modified design full containment concept and scrubbing capability for chlorine; separate enclosure for ammonia feeders but outdoor shielded bulk ammonia storage with sprinklers. The cost could be in the range of $3.5 to $4.5M. ■ Conversion to liquid sodium hypochlorite and ammonium sulfate facilities. The facilities could be outdoors under a shaded area thus eliminating the cost of a building and scrubber. The cost could be in the range of $2 to $3M. Proof For the City of College Station's water production system, Malcolm Pirnie designed a new 40 mgd chlorine feed and storage facility with full containment to replace an aged system that stored containers outdoors. The project also included the latest security provisions. Technical Issue #4 - Evaluate Filter Operations Background The Lake Lewisville plant contains sixteen filters equipped with surface wash, dual (anthracite / sand) media and a variety of underdrains (Wheeler, Leopold type S with IMS caps and ceramic clay tile type). The filter effluent pipe is equipped with a blowoff waste pipe but it is not suitable for filter- to - waste use. We understand that some of the filters boxes have developed leaks and the concrete walls have corroded and need repair. Denton staff has implemented some of these repairs. Approach Water plant filtration serves at the heart of water treatment. The last 20-year trend to enhancing filter effluent performance has increased the need to tighten filter operations (filtration, backwash and media ripening) to an individual filter level. The coagulation process can significantly affect filtration performance thus Malcolm Pirnie will emphasize optimizing it in order to achieve the highest degree of filter performance. This includes optimizing rapid mixing to improve chemical dispersion; improving flocculator performance using low cost and low maintenance hydraulic baffled flocculation; and enhancing settling by eliminating upflow currents at weirs to achieve optimum overflow rates. A water that is properly prepared through coagulation has a better chance of being effectively filtered. Options Malcolm Pirnie could consider includes: • Retrofitting existing filters. • Install submerged membranes in 7 of the 16 filters. • Install submerged membranes In the aft end of the sedimentation basins and convert the filter media to all or part GAC,. With ozone as candidate process addition, it is essential we produce biologically stable water before the plant distributes it to the customers. Thus, media selection, the need for disinfectant free backwash water, and air scour features will be important and will receive the proper level of attention. The filters will be an integral part of any effective ozone treatment scheme. An alternative potential option we can consider includes retrofitting the existing filter boxes with submerged membranes filters. Using for example, Zeeweed® ultrafiltration modules, we can retrofit about seven of the 16 existing filters to achieve the equivalent 30 mgd treatment capacity. The advantage of such an approach is consistent particle and turbidity performance while gaining substantially increased treatment capacity in 30 to 40% of the footprint of conventional filters. In a potential future scenario, and with hydraulic improvements, this could lead to a reasonably economical plant expansion through high rating of the flocculation (hydraulic baffled flocculation) and sedimentation basins (tube settlers), and complete conversion of the filters (membranes). An expansion to between 50 and 70 mgd capacity is possible at the same site. We have evaluated this concept for the Gulf Coast Water Authority where they plan to expand an existing site from 50 mgd to 75 mgd. We found it cost -competitive to retrofit their filters and reduce the need for additional tankage. For the Lake Lewisville plant, retrofitting the filters with air scour and filter -to -waste capability and potentially new underdrains and media would cost about $2.5 to $3.OM. Converting the filters to submerged membranes would likely cost about $8 to $9M. At first sight, this does not appear cost-effective. However, should an expansion of the Lake Lewisville plant be considered, these numbers would converge and the cost benefits of a membrane retrofit would be realized. Another option that would eliminate the need for major modifications of the filters could be installation of low pressure membranes at the aft end of the sedimentation basins and conversion of the existing filters to GAC contactors. The cost would be higher than retrofitting the filters, but because the plant would not need ozone, it can potentially offset cost. II is these leading idea concepts we can assess in the preliminary phase of the project. Proof For the 87 mgd Trinity River Authority plant, Malcolm Pirnie designed a retrofit of ozone and its twenty filters including new air / water underdrains; removing the surface wash and adding air scour capability; modifications of effluent piping and SCADA programming to include filter -to -waste function; and replacement of the old media with new dual media (anthracite / sand). Technical Issue #5 - Evaluate Options for Correcting Hydraulic Deficiencies Background Besides the hydraulic issues identified in the RFP, we observed some additional opportunities for improvements to the existing facilities as is discussed in our approach below. We also recognize that the plant's current hydraulic profile poses significant challenges to integrating process changes that may be required to meet the water quality objectives. Approach Our approach will consider opportunities for improving existing plant hydraulic deficiencies while including cost effective approaches to accommodate the required process changes. For each of the potential process concepts we evaluate, we will conduct a complete hydraulic profile from the raw water intake to the clearwells. lookino for opportunities to simplify hydraulics, improve process effectiveness, and reduce need for additional pumping. Example of Existing Facility Hydraulic Improvements Flocculation Basins. During our site visits, we noted hydraulics deficiencies at the flocculation basins can be improved to enhance flocculation and coagulation: 1. Flow path and distribution between the 3 compartment flocculation zones. Flow enters the center compartment and is forced to the outer compartments through the two horizontal paddle shaft access holes. Forcing flow through these holes at high velocities with paddles churning on both sides of the holes creates significant floc shear. 2. Flow path from floc basin to sedimentation basin. Two small exit holes leading out of each of the outer floc compartments feeding the sedimentation basin influent launder also cause additional floc shear. Among several of the options we could consider is the use of hydraulic baffled serpentine channels, like Hydraulic baffling can reduce maintenance by eliminating most mechanical equipment in the flocculators. we have done for the City of Phoenix, for example. The baffles create the gentle swirling patterns that achieve effective flocculation without need for paddle mixers. Baffling can easily be retrofitted with minimal demolition through insertion of baffles into the existing floc tanks. We would also evaluate the enlargement of the effluent ports from the floc tanks and filleting of the upwells leading to the sedimentation basin influent launders to allow smooth flow with minimal floc shear. With the elimination of the paddle flocculators, there are also additional operational and maintenance cost savings to complement the process enhancements. Example of Process Change Related Hydraulic Improvements For treatment alternative 3 described in our approach (intermediate ozone/GAC filters), if the intermediate ozone contactor is located adjacent to the effluent wall of the existing sedimentation basins we will consider the use of concrete channels to convey flow to the filters, thus eliminating the need for re - pumping. By doing so, we can discontinue the use of the existing settled water channels feeding the filter Hydraulic baffling can reduce maintenance by eliminating most mechanical equipment in the flocculators. ei nuent eno or me ozone contactor into the niter building wrapping around the existing sedimentation basins. Proof For the 87 mgd expansion of Trinity River Authority's Tarrant County Water Supply Project, we used similar hydraulic concepts (concrete channels and tight control of clearwell levels using variable frequency drives on transfer pumps) to integrate settled water ozonation within tight hydraulic constraints. Technical Issue #6 - Evaluate Sludge Removal System Background Each of the eight sedimentation basins contains two settling zones for collecting sludge. The first zone contains sludge collection equipment that sweep settled sludge toward a center hopper. A second downstream zone also contains a hopper but it is not equipped with sludge collection equipment. Reportedly, operators drain and clean basins on a 3- month cycle chiefly due to accumulations within the second zone. In addition, they must manually manipulate sludge drain valves, draining sludge to the sanitary sewer. Approach In streamlining sludge operations, we will focus on cost-effective facility enhancements that 1) optimize sludge settling within the first zone and 2) automate the sludge valves controlled by timers or sludge depth / density. Currently, the two zones of each basin are open and contain no baffling. In large rectangular tanks without baffling, it is our experience they develop currents that can impact the natural gravity sedimentation process. Using a simply hydrodynamic model, we can simulate existing conditions then model again with baffling between the two zones to assess the improvements. The impact of reducing sludge accumulations can be dramatic. Basin Plan nni 4,mr�,d+yn�/l•lf��f in /4nc� nu Computational hydrodynamic modeling is a valuable tool in assessing basin / sludge flow patterns. Another option, considerably more costly, is to install equipment in the second zone of the tanks - either a circular unit or chain and flight or traveling vacuum type (with a constructed level floor) that drags the sludge to the first zone. In our approach, which includes modeling and cost-effective analysis, we can determine the most beneficial improvements that reduce maintenance at an affordable cost. With respect to streamlining sludge draining operations, options include automated actuators that actuate on preset timers or sludge depth using density meters. With the potential baffling improvements between the two zones, modeling may indicate that we would only need to automate the first zone valves and rely on less frequent manual operations of the second zone valves. Technical Issue #8 - Evaluate pH Adjustment System Background pH adjustment is practiced at the Lake Lewisville plant using liquid sodium hydroxide that is injected into the combined filter effluent pipeline ahead of the clearwells. Typically, plant operations will adjust the pH leaving the filters to about 8.0. A common result of feeding caustic in pipelines is plating of the pipe walls with calcium carbonate precipitate that the City removes on a routine basis to restore the pipe to its original diameter. Reportedly, they have also seen an occasional turbidity spike after caustic feed. Approach Achieving a proper balance of pH control is an important aspect of optimizing organics reduction, disinfection maintenance, disinfection by-products control, and corrosion stability. The process design selection that meets the overall treated water quality goals (taste and odor, TOC reduction, disinfection, etc.) will directly influence the right process pH. We know, for example, that low pH in an ozone plant can minimize bromate formation, reduce ozone production needs (since we can maintain the residual longer), and maximize disinfection and taste and odor control. Even in membrane or UV facilities, post pH control is a routine practice since adding lime can create other side effects. Therefore, pH adjustment at the end of the Lake Lewisville plant is likely an appropriate strategy. We will approach resolving issues the City has with using caustic for pH adjustment from two angles: ■ Relocate the caustic feed to the clearwells, install mixing, and institute an automated pH control scheme. ■ Install a caustic injection chamber on the combined filter effluent line to employ mixing to reduce plating when the water re-enters the piping. The benefits of adding a chamber and mixing is we can reduce the plating and the tendency for turbidity blooms since we can eliminate localized pockets of high pH. Technical Issue #11 - Evaluate Reliability and Condition of Plant Facilities and Equipment Background The Lewisville WTP was constructed in two major expansion phases. Some of the facilities from the "first plant" built in 1957 are still in use (e.g., filters with wheeler filter bottoms, etc.). Through an ongoing maintenance program, the City has done an excellent job maximizing the use of these facilities well beyond their intended life. As part of this project, changes are planned to improve the process and position the plant to meet future regulatory needs. Having the plant facilities in optimum condition and at peak reliability with renewed useful life is essential in meeting this goal. We recognize that implementing both condition / reliability improvements plus the process improvements will be a challenge with the planned project budget. Risk (consequence) based prioritization will be needed to make informed decisions. In addition, we recognize that a phased implementation plan that has buy -in from all stakeholders (financial, operations, maintenance, and engineering staff) is also essential. Approach Our approach would identify and prioritize reliability/ condition improvements and develop a phased implementation plan. We have successfully used a derivative of the "RAM-W" process to aid our clients objectively priority critical condition/ reliability needs through a formalized process. First, we would conduct a detailed condition/ reliability assessment of the key facilities from intake to high service. Our team would focus on areas such as: ■ Mechanical ■ Electrical ■ Instrumentation and Control ■ Process ■ Hydraulic ■ Structural ■ Other As we did for the Cities of College Station and Detroit, we would document findings and recommendations in "work order/ scope" format for insertion into your design / construction contracts. Once the needs have been identified and documented, the team would proceed through the process, outlined in the figure below, to develop a prioritized plan. This process is collaborative with all key stake holders to ensure buy -in and inclusion into your CIP. Establish Assessment Needs Define Prioritization Objectives Establish Consequences of Not Implementing Needs Quantify "Risk" of Needs Quantify Relative Priority of Needs .Start Input>' Prioritized List of Needs I Proof Malcolm Pirnie has used this approach to assist a local large utility in successfully identifying the criticality of over 1000 assets in their ongoing CIP program, gaining consensus from staff at various levels along the way. The critical needs from that project accounted for nearly $90M in need -based improvements. Malcolm Pirnie Value -Added Solutions to Other Project Issues From our detailed site visits and contact with City staff, our team has gained insight into areas of the plant that, if considered, can provide added -value to the best overall upgrade program. The following table details a number of additional issues that our team is prepared to address through the project. We recognize with plants the age of Lake Lewisville, we can identify several upgrades well beyond the City's budget. Our approach will be to identify those that can provide the most beneficial return to the City (coupled with the previously discussed process) in terms of improved water quality, improvements to operations efficiency, lowering of maintenance requirements, reducing risk, and consequences if a component does not perform, all in a manner the City can afford. Following the table is an approach Malcolm Pirnie has successfully used on other projects to manage costs.

In addition, as mentioned in the adjacent the City's WWTP previous technical issues, the use of a site that is near the raw membrane retrofit would allow the water pipeline filtration process to be expanded in fewer footprints Malcolm Pirnie's-Approach will Deliver a Facility 1 that Meets all Project Goals within Budget Background Denton, like other utilities, faces doing more for less. As such, our engineering design must consider new approaches to deliver a facility that fully meet treatment objectives but at the lowest reasonable cost. Approach Malcolm Pirnie has developed a multi -pronged approach that controls costs at all phases of the work so that the City can have complete confidence that the budget established at the outset can be met when the project is complete. The flow chart that follows depicts the process that Malcolm Pirnie proposes to use for the Lake Lewisville project to maintain overall capital budget. Project Inception: The project construction budget is established and approved with known impacts to customer rates and other aspects of the capital program. Our team will use this number as the target final goal throughout all phases. Predesign: At this stage, we would confirm the sufficiency of the project budget through additional detailed cost opinions based on a concept design that meets the objectives established at the project outset. If the project scope exceeds the budget, our Adeguate fundvg tomruVucl Prgecl Meets Budget Options Develop and prioddza bid Exceeds Bud get alternatives to achieve budget ;30 Reduce scope of proled/defer 75% and BD% items to future phases Conduct detailed design VE t Cosill call Se4at Mitimize change ortlers team would develop options for the City to consider, as outlined in the flow chart. Design: Most cost overages can occur during detailed design when specific detail and features are developed for the project. As such, our team would prepare cost opinions at various stages so that these changes are captured. For any escalations, especially if they result in a budget overage, we will explain them and offer options to maintain budget, as outlined in the flow chart. Bidding: Malcolm Pirnie's focus is to enable the City to respond effectively to multiple outcomes at the bid phase so that the project budget and schedule are safeguarded. Construction: While most cost control measures usually precede this stage, it is change orders that measure the effectiveness of those measures. Our construction effort will focus on responsiveness and creative approaches to reduce change order impacts that do arise. Effective cost containment approach throughout all phases will deliver an on budget project.
