WITNESSETH, that in consideration of the covenants and agreements h.erein contained, the parties hereto do mutually agree as follows: .. � 1; � � •! , The OWNER hereby contracts with the CONSULTANT, a licensed Texas architect or en i� neer, as an independent con.tractor. The CONSULTAIVT hereby agrees to perform the services as described herein, with diligence and in accordance with the professional standards custo�narily obtained for such services in the State of Texas. The Project shall include, without limitation, professional engineering services in suppart of developing a computer model to model the plant processes for optimizing the chemical usage for phosphorous removal, energy ei'ficiency, methane generation and optimization of the processes during dry and wet weather at the Pecan Creek Water Reclamatian Plant far the City of Denton. The Pecan Creek Water Reclamation Plant (PCWRP, Map-Exhibit 1) permit from Texas Commission on Environtnental Quality (TCEQ) was modified by TCEQ to add phosphorous remaval down to 0.5 milligram per liter in the permit issued in June 2013. Wastewater department has three years to design and construct the facilities to meet the phosphorous limit permit deadline. Currently the final design using chemical removal af phospharous is underway by the consultant retained by the wastewaier department. The PCWRP has permitted capacity to treat 21 million gallons per day average daily flow. The current flows treated at the plant are averaging 15 million gallons per day. As such, there is excess capacity in the plant process units. The intent of the plant process computer model development is to evaluate the current excess capacity ta treat the influent phosphorous biologically and thereby optimize the use of ferric chloride that will be used for the remaining phosphoraus removal. In addition, the process model will evaluate current energy usage for treatment and provide optimal level af aeration to make the aeration process and energy use more efficient, and evaluate methane gas production in the digesters. The computer model will also allow plant personnel to evaluate "what iY' options to optimally operate the plant under varying loading conditions during dry as well as wet weather conditions. The model will also allow evaluation af the side stream flows that will be especially important with chemical addition for phosphorous remaval, The computer model will thus allow plant aperations staffto see the big picture and also provide the ability to get down to evaluation of each process for optimal aperation as well as trauble shooting if there are process disruptions. The main tasks and objectives for the project include the following: Task/Objective 1- Develop and deliver to the City a fully calibrated plant process model using BioWinTM 4.1 for the current plant configuration, operation, and influent and effluent data. The plant model will be calibrated to a level that is sufficient to accommodate future nutrient removal planning, chemical feed optimization far phospharus removal and confirmation of design criteria. The model will also be validated far wet weather simulations using the City's historical wet weather data. • TasWObjective 2- Develop and deliver to the City an operations tool ta assist wastewater treatment engineers and plant aperators in optimizing operations of the plant including chemical feed for phosphorus removal. • Task/Objective 3- Provide training to the City staffon the use ofthe calibrated model and the operations tool for use in operations, planning, and design. The detailed requirements of Tasks 1-3 are further defined within the Scape of Work within A chment A. All completed documents or reparts are to be reviewed by OWNER's personnel follawing CONSULTANT's in-house quality control and quality assurance pracedures prior to submission. The OWNER will provide CONSULTANT with one consolidates set of comments on documents or reports upon completion of its' intemal review. Any additional services requested shall result in a change order to the authorized purchase order, and an amendment to this contract. ,.. � � � , • The CONSULTANT understands that the goal of this project is to provide professional assistance in developing a calibrated wastewater treatment process model and operations tool for the Pecan Creek Water Reclamation Facility (PCWRF). One purpose of the process madel is to simulate and validate impacts of future planning scenarios including flow/load variations; evaluatian of operational strategies to maximize the use of existing infrastructure and delay capital expenditure; evaluation af potential nutrient removal potential including biological and chemical phasphorus removal; assessing impacts for side stream flaws and co-digestian; optimizing pracess canfigurations; define wet weather protocols and standard operating procedures; optimizing operational costs including energy usage; etc. The CONSULTANT further understands that the City af Denton would like to use the process model as an operations training and optimization tool that can be used by City StafFto train and understand impacts of process decisions and optimize operations to lower O&M costs.

One purpose of the process model is to simulate and validate impacts of future planning scenarios including flow/load variations; evaluation of operational strategies to maximize the use of existing infrastructure and delay capital expenditure; evaluation of potential nutrient removal potential including biological and chemical phosphorus removal; assessing impacts for sidestream flows and co-digestion; optimizing process configurations; define wet weather protocols and standard operating procedures; optimizing operational costs including energy usage; etc. In addition the City of Denton would like to use the process model as an operations training and optimization tool that can be used by City Staff to train and understand impacts of process decisions and optimize operations to lower O&M costs. Project Objectives The main objectives for the project include the following: • Develop and deliver to the City a fully calibrated plant process model using BioWinT"^ 4.1 for the current plant configuration, operation, and influent and effluent data. The plant model will be calibrated to a level that is sufficient to accommodate future nutrient removal planning, chemical feed optimization for phosphorus removal and confirmation of design criteria. The model will also be validated for wet weather simulations using the City's historical wet weather data. • Develop and deliver to the City an operations tool to assist wastewater treatment engineers and plant operators in optimizing operations of the plant including chemical feed for phosphorus removal. • Provide training to the City staff on the use of the calibrated model and the operations tool for use in operations, planning, and design. Project Scope This section describes the details for the process model development and training scope. Task 100: Process Model Development and Training Subtask 101: Review Existina Information and Develoa Flows and Loadinqs Criteria ENGINEER will review information provided by the City for the PCWRF to be modeled and become familiar with the current processes at the plant. Scope of Work �"��,� . � �� .�� Pecan Creek WRF Process Modeling Page 1 of 14 ��0i`��°°°W��'�0 �"�"��v�"� ��`�°��°o�°' Three years of operating data will be reviewed to establish current influent loading criteria. ENGINEER will review the historical plant data in conjunction with the current data in order to establish design flow and loadings to the PCWRF. Operating data will include parameters listed in the assumptions section below. Any parameters listed in the assumptions section that are not available to the ENGINEER may be included in the supplemental sampling plan. Key activities will include: • Summarize three years of operating data in an Excel spreadsheet. Create the following plots to understand treatment plant operations and pertormance: o Influent concentration and load vs time for: BOD, COD, TSS, TKN, ammonia, TP, pH, alkalinity o Influent and primary effluent concentrations and load vs time for: BOD, COD, 7SS, TKN, ammonia, TP o Effluent BOD, TSS, TP, and nitrogen speciation (TN, ammonia, TKN, and NO3/NO3) vs time o Primary and secondary clarifier overtlow overflow rates (gpd/s� vs time o Total and aerobic SRT vs time o MLSS and MLVSS vs time o Total and secondary yield vs time o Solids production and influent BOD, TSS, and COD load vs time • Pertorm statistical analysis to identify typical load peaking factors for maximum day, maximum month, and peak week loading. Establish current flow and load. • Conduct mass balances on TSS and VSS throughout the plant, as well as around primary and secondary clarifiers. This information is used to assess data quality for the calibration. • Select a period to which to calibrate. ENGINEER will review existing process performance using three years of plant monitoring data provided by the City. ENGINEER will identify existing issues related to data and process pertormance. The findings of this review will be reviewed during the site visit and used in the development of the supplemental sampling plan. ENGINEER will conduct a one day site visit to the plant during review of the existing information. The purpose of the visit will be to review current operations, develop understanding of treatment processes at the plant, and to identify potential issues that need additional clarification or sampling. Locations for process sampling will also be verified during the site visit. Assumptions: The City will provide record drawings for the PCWRF, preferably electronic versions in PDF and AutoCAD format. They City will provide current operations and maintenance manuals for unit processes for which they are available, The City will provide planning reports, historical data, monthly operating reports (MORs), and other plant data. It is assumed that information will be provided by the City in electronic format (Microsoft Excel), when possible. Specific historical parameters used to develop the process model includes, but is not limited to: o Influent: Flow Rate, Temperature, pH, Alkalinity, CBOD, COD, TSS, VSS,TKN, Ammonia, Nitrate, Nitrite, Total Phosphorus (TP), Ortho-P and Volatile Fatty Acids Scope of Work � �.,�"� �� Pecan Creek WRF Process Modeling Page 2 of 14 a��°°W��mw°°'° �:°°m°�w�� °��a°�"u o Primary Effluent: Flow Rate, CBOD, TSS, Ammonia, TP, TKN, # of clarifiers in service o Final Effluent: Flow Rate, CBOD, COD, TSS, TDS, TP, Ortho-P, Nitrogen Speciation (TN, Ammonia, TKN, Nitrate, Nitrite) o Primary Sludge: Wasting Rate o Aeration Basin: MLSS, MLVSS, SVI, SRT, Air Flow Rates, DO o Secondary Clarifier: Blanket Depth, # of clarifiers in service o Primary Sludge: Flow, TSS, VSS o WAS: Flow, TSS, VSS o RAS: Flow, TSS, Nitrate o Thickened WAS: Flow, TSS, Polymer Usage, Filtrate TSS o Digester: Feed Rate, Temperature, Methane Produ�tion, SRT, Effluent TSS, Effluent VSS, pH, # of digesters in seniice o Belt Filter Press: Feed Rate, TSS, Polymer Usage, Cake Concentration, Filtrate TSS o Return Flow (from solids handling): Flow Rate, TSS, Ammonia, Nitrate, TP, Ortho-P The process model criteria will be based on the previous three years and will include projections / estimates of future flows up to the design capacity and loads. Historical criteria for minimum month, annual average, 30-day max average, and peak wet weather flows will be estimated based on data analysis. No flow monitoring or collection system analysis will be pertormed as part of this project. Future criteria estimation (beyond current design criteria) will not be considered as part of this project. Meetings: A one day (8 hour) site visit will be conducted with the following goals: o Interview plant operations staff (plant manager and operations manager) to become familiar with the site, current process flow scheme and performance, and to seek input from project staff on current issues / problems o Review historical data analysis from available plant data and clarify anomalies in trends o Confirm PCWRF process flow diagram and perform plant walkthrough Deliverables; Electronic copy (PDF format) of the PCWRF flow and load trend analysis including, at a minimum, plots listed above.

Subtask 102: Process Model Development and Calibration ENGINEER will develop a tailored and calibrated process simulation model of the PCWRF using BioWinT"" 4.1. The process model will be developed with sufficient detail to allow users to manipulate individual treatment trains where desired by the City (i.e., individual treatment trains will be provided in the models). Scope of Work � tl��"�� .� tl Pecan Creek WRF Process Modeling Page 3 of 14 ��6o��°�m�°°° °`°°�'��"� �`ow�o`�°'a Prior to field sampling, the model will be developed and initially run with available historical data. Issues generated from the initial effort will be used to refine the supplemental sampling plan for the plant (discussed in subtask 103). After sampling, data collection, and analysis, the model developed will be calibrated using historical data and data gathered during the supplemental sampling. The model will be calibrated to the generally accepfed calibration Level 3. Generally, model calibration follows the following steps after the initial model setup and runs under historical data: • Revise influent fractions for wastewater based on supplemental sampling and historical data. Typically, this is an iterative process. • Run model simulations using supplemental sampling period. Compare results to actual operating data. Typically, solids quantities and concentrations and effluent values are reviewed, • Make modifications as necessary to operations related parameters in the model to close mass balances and depict performance on a unit process basis. • Make modifications to kinetic model parameters if necessary. Typically, modifications to these parameters are not made unless there is clear evidence that these changes are justified. In general, use of calibrated process models allows the evaluation of the following: • Plant specific chemical feed optimization for phosphorus removal. • Plant specific BNR strategy evaluation and optimization. • Predicted effluent constituents including nitrogen and phosphorus species, BOD, COD, TSS, and ammonia. • Predicted solids concentrations in the biological process. • Predicted solids production from plant processes. • Oxygen demand from plant processes. • PerFormance of plant processes under different flows, temperatures, and loading combinations. • Performance of plant processes under wet weather events (including constituents mentioned above), and optimization of wet weather operational strategy. • Impacts of recycle streams. • Solids streams, including stabilization processes. • Process risk and reliability associated with numbers of trains and unit processes in service. Assumptions: The ENGINEER will develop two model configurations including: one for current operation and basin configuration and one for improvements required to provide biological phosphorus removal. Two operational scenarios will be developed using the current basin configuration including: o Bio-P removal and chemical usage reductions with existing infrastructure (cost savings in chemical) o Aeration / DO adjustments to optimize air usage (cost savings in energy) The calibrated model workshop will include review of the two operational scenarios described above. At present, limitations of process modeling include the following: Scope of Work � P.,B�� , � Pecan Creek WRF Process Modeling Page 4 of 14 dsrdea�mreownoea �rnmtnmw�u ��commt��ta o Models cannot simulate the fate of compounds of emerging concern (including personal care products, growth hormones, nano materials, etc.), radioactive constituents, toxicity, or heavy metals. o Models cannot predict short circuiting, back mixing, or uneven flow distribution unless specifically input into the model. However, if flow distribution and mixing is a concern computational fluid dynamics (CFD) can be used to troubleshoot the issue as described in Subtask 108. o Models cannot predict settleability issues associated with filamentous organisms, bulking, or foaming. Manual inputs must be made to the model for poor settling conditions. o Models do not have a built in safety factor, and therefore, biological processes will continue until the minimum conditions are reached. Safety factors are typically applied to design to account for unpredictable field conditions. • Performance of secondary clarifiers relative to solids removal will be simulated using available models within the simulation software. Specific CFD models of the clarifiers will not be developed under this scope. • Level 3 model calibration includes calibration with field collected data and will be consistent with the procedure used for performance calibration with other plants with effluent nutrient requirements. • Model will be calibrated to generally accepted standards of Level 3 model calibration accuracy targeting less than 10% differences on solids balances. • Model calibration will be verified through comparison of daily historical data for a period of six months to one year. In addition, model will be verified through comparison the supplemental sampling period on an hourly basis. • Wet weather model validation will be analyzed using the City's historical wet weather data. This does not include supplemental sampling during a wet weather event, The analysis includes the following: o The ENGINEER will analyze the five largest storms to develop a representative storm hydrograph. o The ENGINEER will create dynamic wet weather simulation model that the City can use for subsequent evaluations. This would typically involve maximum month load at minimum week temperature and a specified design storm. • The degree of accuracy on individual constituents will be agreed to during the calibration process with the City and ENGINEER. • Studies for kinetic model parameter verification are not included in this task. If needed for process modeling, and if requested by the Ciry, ENGINEER can provide additional laboratory and field sampling to verify kinetic parameters that are found to be significantly different than standard default values as part of an additional service authorized by the City. Meetings: � One half day (4 hour) workshop to review initial model process flow, operation characteristics, additional sampling requirements and proposed locations. (after initial model run, before complete calibration and supplemental sampling) • One half day (4 hour) workshop to present the calibration results including verification plots and discussion of the two operational scenario adjustments and results.

Subiask 103: Process Supplemental Samplina Plan ENGINEER will develop a concise and tailored Process Supplemental Sampling Plan for PCWRF. The purpose of supplemental sampling is as follows: • Determine diurnal loading patterns for influent constituents. • Determine detailed influent fractions for modeling calibration. • Gather additional data on side streams. • Gather data for verification of default kinetic rates within model. • Gather data on areas of plant that require additional characterization. Developing a supplemental sampling plan typically involves the following: • Identify locations for composite and grab sampling. Determine the parameters to quantify at each location to gather requisite information for the model calibration. • Prepare a written sampling plan. Coordinate with City operations and laboratory staff prior to sampling dates. Upon approval of the sampling plans by the City, sampling will be pertormed, followed by a period for data review (during this time calibration can also begin). It is assumed that ENGINEER will collect, analyze where possible, and coordinate contract analysis of samples taken during the effort. Assumptions: • The ENGINEER wilf perform two supplemental sampling events; one during the winter season and one during the summer. Each sampling event will require three (3) personnel for three (3) days and ten (10) hours per day. • The majority of analyses will be performed by either ENGINEER or the City's laboratory. ENGINEER will coordinate the City's staff / laboratory to provide sample pickup and analysis. The City will expense all laboratory analysis separate from this contract. Outside laboratory analysis costs are not included as part of the ENGINEER's contract. .� Depending on the historical data available, the ENGINEER may require assistance from the City to develop additional analysis on samples currently collected by PCWRF. • Additional sampling for wet weather event validation is not included in this task. � A specific lump sum item has been included in the direct costs to cover the ENGINEER's consumables related to the sampling and analysis performed by the ENGINEER. • It is assumed that responsibility for the sampling and analysis will be divided as follows: o Composite sampling and analysis will be conducted by the City staff o Grab sampling in aeration basins will be conducted by H&S. Analysis will be performed by both H&S staff and City laboratories o Grab sampling of sidestreams will be conducted by H&S.

We have provided comprehensive engineering services for hundreds of wastewater treatment facilities in the U.S. and worldwide, featuring a wide range of capacities from less than 1 mgd to more than 1 bgd, We have successfully designed traditional primary treatment facilities, advanced high level disinfection facilities, and everything in between, Our applied research group keeps innovative options front-of-mind, fostering consideration of smart, forward-thinking alternatives. Many of our projects are complex in nature and have strict consent order deadlines that need to be met. For these projects, we often mobilize "SWAT Teams" upon project initiation. The SWAT Team — composed of the facility leads, discipline leads, and team experts in operations and automation — will establish a unified basis of design early in the project based on the feedback of experts and the best of collaborative thinking. By including operations-oriented engineers and licensed treatment plant operators, we ensure facilities that we deliver will be easy to operate and maintain, energy-efficient, and cost-effective, This process can jump-start the design, save money and tlme, and equip our team members with the information necessary to address various design issues, conduct the appropriate evaluations, and expedite preparation of the Basis of Design Report, [_J��`F�� f�� p�P k�.i�� ,�r °ic�c°�w�v� Hazen and Sawyer has been involved in liquid and solids process upgrades at the Neuse River NMlfP for more than 25 years, from its expansion from a 30-mgd extended aeration activated sludge facility to �4 �rCd ��r�� l��s�r�F�;�� ii�ofii[�.� �P ��^rr�rE�i,r1�.4��i��E��Pfl�, r��°o��i�� rv.w�"[,ii iit,�..e�i (< <��ht��exl� �v (�� '.(ti ii�Eg��, (!� ;iwr� . �f "� r'ruer�l 4��°`)�r�'f[E<<�i�k lirY��i��, Hazen and Sawyer is currently working with the City of Raleigh on an expansion lo a permitted flow capacity of 75 mc�d while continuinc� to meet the high level effluent treatment results currently being achieved at the treatment plant. �I) � , , f �r Ta maximize efficiency �nd ensure a comprehensive, collaborative design process, Heren and Sawyer utilizes 3D CAD models io provide virtual walk-thrus of facilily desic�ns that help to elimin�tte conflicts and optimize oper�bility. 3D models can also bo used to expedite complex permiitin,y processes to keep a project on schedule, as was �he case recenily for the Cily of Tallahassee.
