SANITARY SEWER SYSTEM OVERVIEW The City of Melissa, Texas is projected to have significant future growth which will exceed the capacity of the city's existing and currently planned sanitary sewer system. In addition, wastewater generated within the City of Anna, Texas flows through the City of Melissa in a network of interceptor sewers owned and managed by the North Texas Municipal Water District (NTMWD). Anna, Texas is also expected to grow significantly in the coming years. An overview of the Anna/Melissa area sanitary sewer system was provided in the recently completed Upper East Fork Interceptor System (UEFIS) Regional Capacity Assurance Phase 3 Final Report prepared by Jacobs Engineering Group, Inc. dated August 2024. The overview reads as follows, Both the cities of Anna and Melissa have significant future growth projections exceeding existing conveyance capacity. The near -term growth will occur in the western areas of both communities, and most of the long-term growth would occur on the east sides of both the Anna and Melissa service areas. The growth in the western portion of the communities would be conveyed in the existing Clements Creek and Throckmorton Creek interceptors and collected at the planned Clements Creek Lift Station for pumping to the Sister Grove RWRRF. The eastern terrain in Anna and Melissa naturally flows southeast. away from the existing sewers in the western portions of the service areas, To convey the flow that would be collected in the southeast of Anna. two alternatives were identified for routing flow from southeast Anna that included the following: • Pump flow from southeast Anna west toward Clements Creek Interceptor and improve the conveyance capacity of the existing Clements Creek sewer to handle this additional flow. Once the flow is delivered to the Clements Creek Interceptor route, alternatives are to intercept this flow along the Clements Creek interceptor route and pump the flow directly to the Sister Grove RWRRF. • Pump flow from southeast Anna toward the south, directly to the Sister Grove P,WRRF. Similar to the aforementioned Anna options. conveyance options from eastern Melissa also considered a direct pumping option to the Sister Grove RWRRF. It is understood that the Cities of Anna and Melissa wish to create a model of its sanitary sewer collection and pumping system and use that model to predict the adequacy of Melissa's sanitary Proposal for Engineering Services Sanitary Sewer System Modeling and Preliminary Engineering Report Anna and Melissa, Texas February 18, 2025 Page 2 sewer system under near -term (within the next 10 years) development conditions and long-term (full city buildout) conditions. The model will also consider anticipated future wastewater flow from the City of Anna. Once the near -term and long-term -bottlenecks" within the system are identified by modeling, a preliminary engineering analysis will be conducted to determine sanitary sewer system improvements needed to alleviate the "bottlenecks. WSB will provide the following engineering services for the sanitary sewer system modeling and preliminary engineering report for this project. SANITARY SEWER SYSTEM MODELING AND PRELIMINARY ENGINEERING REPORT SERVICES Project Management WSB will perform all work necessary to effectively coordinate the project development, maintain the project's schedule and budget, as well as manage the Project Management Team (PMT) starting with a Project Kick-off Meeting. Project management measures will ensure that the project is completed on time, within the budget, and in accordance with applicable laws, policies standards, and good engineering practice. Kick -Off Meeting WSB will attend one (1) modeling and engineering report kick-off meeting with City of Melissa staff to review the proposed scope of the project, identify goals for a successful outcome and formalize the project schedule. The meeting will be held in person and via Zoom so that WSB staff working on the project from remote locations can join the meeting. Data Collection and Review of Previous Reports WSB will collect data on the City of Melissa's existing wastewater conveyance system, to include; layouts, sizes, elevations and slopes of existing sanitary sewer mains eight (8) inches in diameter and larger. WSB will also collect information on all existing wastewater lift stations owned and operated by the City of Melissa. Existing data on wastewater flows within the existing system will be collected, including data on wastewater flows from the interceptor sewer lines exiting the City of Anna at the Throcknmorton Creek, Clements Creek and Stiff Creek points of entry (POE). WSB will review planning and engineering documents from the City of Anna, the City of Melissa, and the City of McKinney (Clemons Creek) including but not limited to; comprehensive municipal plans containing land use and zoning maps and other pertinent information, comprehensive sanitary sewer plans, engineering reports on sanitary sewer system improvements, and plans and specifications on specific wastewater infrastructure projects. WSB will conduct a thorough review of the recently completed Upper East Fork Interceptor System (UEFIS) Regional Capacity Assurance Phase 3 Final Report prepared by Jacobs Engineering Group, Inc. dated August 2024. SewerCAD Modeling WSB proposes to create a model of all existing "trunk" sanitary sewer pipes within the City of Melissa with a diameter of 12-inches or greater. (All pipes less than 12-inches in diameter will be identified and analyzed as "sewersheds' with the combined flow in the pipes less than 12-inch diameter in each sewershed modeled as entering the trunk sewers at single points of entry (POE). WSB proposes to use the modeling tool known as "Bentley SewerCAD v10". The Bentley SewerCAD software is the most commonly used sanitary sewer modeling tool for systems the size of the City of Melissa. Proposal for Engineering Services Sanitary Sewer System Modeling and Preliminary Engineering Report Anna and Melissa, Texas February 18, 2025 Page 3 WSB will estimate peak hourly wet weather (PHWW) flows throughout the City of Melissa wastewater conveyance system by utilizing existing and proposed land uses along with historical data on wastewater flows occurring during periods of wet weather. Data from flow meters installed on interceptor sewers and City of Melissa lift station flow measuring devices (actual flow meters or pump run-time meters), along with peaking factors provided in the Texas Commission on Environmental Quality (TCEQ) standards for wastewater collection systems, will be used to calculate peak flows. Peak wastewater flows will be calibrated using flow data from downstream flow meter stations on interceptor sewers. Preliminary Engineering Report WSB will prepare a preliminary engineering report containing analyses of the SewerCAD modeling runs and recommendations for improvements to the City of Melissa sanitary sewer collection and pumping systems identified as needed to eliminate system bottlenecks. Cost Estimates WSB will determine options and provide project cost estimates for proposed sanitary sewer system improvements, to include new or upgraded trunk and interceptor sewers and new or upgraded lift stations. Projects will be separated by sewer basins, broken down into three (3)- year time blocks and spread out over the next 30 years. Best estimates of the effect of inflation on construction costs will be provided. Deliverables The following deliverables will be included: • Signed final report (including maps and cost estimates) in PDF electronic format. • SewerCAD Models of the City of Melissa wastewater conveyance system, one based on the proposed near -term system and a second based on the proposed full build -out system. • All supporting documentation. Exclusions Additional items and work tasks NOT included in the scope of services provided by WSB at this time include; 1.) Survey services. 2.) Geotechnical services. 3.) Right-of-way or property acquisition services. 4.) Construction -phase infrastructure design services. SCHEDULE AND FEES Project Schedule WSB will begin the project coordination and subsequent modeling and report preparation immediately after authorization of this proposal. The proposed schedule includes the following timeframes: Task Timeframe Kick -Off Mtg., Data Collection.
