This engineering firm will evaluate the current technologies and help Winter Springs select the best plant type based on treatment types, capital costs, maintenance costs and site constraints. The final product will be a conceptual design of both the East and West Waste Water Treatment Plants. The project is estimated to be completed in eight months at a cost of$ 453,938.98. RECOMMENDATION Authorize the City Manager to execute a Purchase Order with Carollo Engineers for the selection of the new treatment processes and conceptual site design for the East and West Waste Water Treatment Plants. 1 Engineers...Working Wonders With Water® ;n0 Fair R,,hina�rn Street,Suite 1400,Orlando,Florida 32801 P.407.478.4642 F.407.478.4643 Exhibit A City of Winter Springs East and West WRF Conceptual Design Reports June 3, 2021 SCOPE OF SERVICES GENERAL The City of Winter Springs(CITY)owns and operates two wastewater treatment facilities:the East and West Water Reclamation Facilities(WRFs), respectively. Both facilities are nearing the end of their useful life and are in need of replacement. Carollo Engineers, Inc. (CONSULTANT)was selected to prepare conceptual design reports for design of each facility's upgrades. The following presents the specific tasks that will be performed as part of this Scope of Services. Certain assumptions have been made in preparing this Scope of Services.To the extent possible,they are stated herein, and are reflected in the attached project budget. TASK 1—PROJECT MANAGEMENT Task 1 includes aspects of project and quality management to provide effective delivery of the project. Specific items included in Task 1 are detailed in the subtasks described below. Task 1.1—Project Management, Communications, and Meetings The CONSULTANT will provide overall project management and communication between its staff and the CITY.The CONSULTANT will track and manage the budget, project tasks, and schedule. The CONSULTANT will attend and manage project meetings and site inspections.A project kickoff meeting will be held with CITY staff to discuss data request items. Task 1.2—Monthly Progress Reports CONSULTANT will provide monthly progress reports that identify the work that has been performed during the month and the work that is anticipated in the upcoming month.These reports will be delivered as part of the monthly progress payment request. Task 1 Deliverables: • Meeting sign-in sheet and agenda(hard copies to be provided at meetings) • Meeting minutes(pdf) • Monthly progress reports(pdf) East and West WRF CDRs Draft 5-10-2021.docx WAT E R OUR FOCUS OUR BUSINESS OUR PASSION 2 City of Winter Springs East and West WRF Conceptual Design Scope of Services Page 2 TASK 2—DATA COLLECTION AND PLANNING FRAMEWORK The CONSULTANT will collect and review existing reports and operating data pertaining to the two facilities.This will include previous reports evaluating the facilities, previous design reports, record drawings, raw wastewater quality and quantity for the past three years, and GIS and population data for the service areas. Task 2.1—Service Areas and Population Utilizing the data collection,the CONSULTANT will evaluate the service area land use and population and establish future population projections. Historical wastewater quality and quantity will be used in concert with the population projections to develop the design criteria for the future facility upgrades, including flows, loads, and peaking factors. Consideration for existing and future regulations will be included. Note that this task assumes a review of existing City established growth plans. Existing data will be utilized based on historical facility flows and a general estimate of growth, as provided by the City. This task does not include a parcel level analysis. Task 2.2—Historical and Projected Wastewater Flows and Loads Based on the identified service area, population and growth, along with historical facility flows, a projected flow will be developed for each facility. These flows will be utilized for ultimate decisions in sizing each respective facility. Task 2.3—Summary of Design Flows and Load A summary memorandum will be developed to summarize and document the results of the previous tasks. This will include a summary for each treatment facility, with the memo to be integrated into the final report at the end of the project. Task 2 Deliverables: • Draft and Final Summary Report Monthly progress reports(pdf TASK 3—SUMMARY OF EXISTING FACILITIES For each facility,the CONSULTANT will conduct an assessment of the existing facilities. The intent will be to gather an overall understanding of the facilities, including the condition of existing components, along with collection of site data in order to determine future areas for potential structures. It is anticipated from this task and forward, due to need identified by the CITY,that the East WRF effort will be prioritized over the West WRF effort. Ultimately they will be presented in one combined report, but it is anticipated they will be separate sections or appendices.

Task 4.1—Evaluate Treatment Process Alternatives • Identify Treatment Process Alternatives—Develop a list all currently available treatment processes that may potentially be used for treatment at the East and West WRF.This list will carollo.com 5 City of Winter Springs East and West WRF Conceptual Design Scope of Services Page 5 include only those processes that have been developed and in use at full-scale. Some similar processes will be grouped together. • Short-list viable candidate processes—The universe of alternatives will be shortlisted to approximately ten that best meet the CITY's criteria.The alternatives will be selected based on o National experience and use of the process. o Record of performance for full scale installations. o Representation of viable forms of emerging treatment processes ortechnologies. • Description of viable candidate treatment processes—Develop a fact sheet for each of the short-listed process configurations. Each fact sheet will include the following information: o A brief description of the process. o A simplified process flow schematic that shows the general arrangement of various secondary- and tertiary-treatment unit processes including recycle streams. o A table of basic facts about the technology, i.e., perceived process reliability, major advantages and disadvantages, operational considerations, relative energy usage, footprint, sludge production, chemicals used, and impact on neighbors. Task 4.2—Structured Decision Analysis • Decision Analysis--A structured decision analysis will be used to characterize the treatment process alternatives and rank them according to how they met a set of prioritized (or weighted) evaluation criteria.The proposed criteria for evaluation are(these criteria can be modified by the CITY): o Established Technology o Treatment Effectiveness o Operability o Constructability& Sequencing (implementability) o Footprint requirements and Flexibility for Future Upgrades • Weighting Criteria-To indicate the relative importance of each criterion in evaluating and comparing the process alternatives,the criteria will be weighed against one another using a paired comparison method.The CITY will participate in the paired comparison exercise during a half-day workshop. • Ranking the Alternatives-To identify the relative performance of each alternative,the unweighted scores from the alternative scoring matrix will be combined with the weights of the major criteria in a commercially available decision model.The decision model calculated a unit- less"decision score":the alternative that best met the most important criteria will receive the highest decision score. TASK 5—UNIT PROCESS SIZING AND FINAL PROCESS SELECTION CONSULTANT will perform process modeling to simulate anticipated performance to meet the design flows and loadings, reclaimed water limits and performance targets, and summarize anticipated mass balances for the two alternatives selected in Task 4. CONSULTANT will then evaluate the two process alternatives for carollo.com 6 City of Winter Springs East and West WRF Conceptual Design Scope of Services Page 6 economic(capital and operational)and non-economic factors, including compatibility and interaction with future phasing, and summarize the pros and cons associated with each selected alternative. This scope assumes that the current method of solids processing at both the East and West WRF will be continued as part of the upgrades and improvements.Therefore, no evaluation of solids processing or stabilization is required or included in this scope of work. Task 5.1—Process Mass Balances and Review • Perform Process Modeling- Develop a plant-wide process simulation model to validate proposed treatment trains, including preliminary treatment; aeration basins, secondary clarifiers and tertiary filters, (or alternative membrane bioreactors); internal plant recycle streams and recycle streams from the solids dewatering facilities.

Refine the treatment system alternatives through mass balance and process calculations. Process calculations will include anticipated start-up, design MMADF conditions, based on the design wastewater flows and loadings. BioWin, GPS-X,etc. computer simulation is not anticipated as part of this effort. • Develop Mass Balances- Develop mass balances for BOD, NH3-N,TN,TP,TSS and VSS throughout the proposed liquids and solids processes forthe East and West WRF, in conjunction with the process modeling efforts. • Process Modeling Review Workshop- Facilitate a meeting or workshop with CITY to review the process modeling simulations and mass balances priorto developing treatment train alternative layouts and conceptual costs. Task 5.2—Liquid Stream Treatment Selection • Develop Alternative Liquid Stream Site Layout Requirements- Review and develop a proposed site layout of treatment processes, based on the evaluated alternatives. Site layout for liquid stream components will identify the existing facilities at the site; potential unit processes; anticipated increments for plant expansions; setback requirements on all sides of property; and general flow stream layout and unit process locations. NOTE: Detailed arrangement of equipment to be located within various buildings and facilities will be completed under subsequent phases. • Perform Preliminary Hydraulic Modeling - Based on proposed site layout of selected treatment process, develop a plant-wide hydraulic model and perform model runs to develop a preliminary hydraulic profile that will show key elevations of proposed hydraulic structures, as well as the average daily and peak hour design flow hydraulic gradients for selected treatment train. Consult with CITY on basin sizing and layout,yard piping sizing and layout, and other hydraulic impacts. • Evaluation - Evaluate selected process alternative for economic(capital and operational)and non-economic factors, including compatibility and interaction with future phasing, and summarize the pros and cons associated with each selected alternative. Perform an assessment carollo.com 7 City of Winter Springs East and West WRF Conceptual Design Scope of Services Page 7 of unit operations,to meet current and anticipated permit,flow, loading and/or site requirements to reliably produce public access reuse water quality.
