TO: Honorable Town Board FROM: Jason Foote, Town Engineer DATE: October 26, 2026 SUBJECT: Town Engineer re Sanitary Sewer Overflow Update Requested Action: Please find attached a chart summarizing the individual and total sanitary sewer overflow volumes from 2022 through year-to-date 2026. As shown, the Town has made substantial progress in reducing overflow volumes, with the most significant improvement occurring at the West Seneca West Bus Garage location, where reported overflow volumes have decreased by more than 80%. The Town is planning to install flow meters on the discharge piping for the Bus Garage and Plant 5 overflow pumps to provide more accurate measurements of overflow volumes. Additionally, level controls will be installed at the Bus Garage to automatically start and stop the pumps based on system conditions, helping to prevent unnecessary bypass pumping. The Town also plans to upgrade the flow meters where sanitary sewers within Sewer District No. 12 discharge into the Erie County trunk sewer. These improvements are intended to eliminate inaccurate flow readings caused by surcharging conditions within the County's sewer system. The flow meter installations and upgrades are anticipated to take place this winter and next spring. Finally, the Town is planning to upgrade its SCADA system and integrate the various flow meters into a centralized platform, allowing data to be collected, monitored, and accessed remotely. Collectively, these improvements will enhance the accuracy and reliability of flow and overflow data, improve system monitoring and operational efficiency, and provide the Town with better information to evaluate system performance and prioritize future sanitary sewer improvements. Should you have any questions or need further clarification, please don't hesitate to reach out. Page 42 of 172
