BACKGROUND
PROJECT PURPOSE
• The 2021 Buffalo Creek Interceptor System Capacity Assessment & Assurance report identified the need for additional capacity in the Buffalo Creek System to meet projected demand growth in the cities of Forney, Heath and Rockwall.
• A 2023 Feasibility Analysis for Conveyance Alternatives Report recommends a new Buffalo Creek Lift Station No. 2 to convey flows from the Buffalo Creek Interceptor System to the new headworks at the South Mesquite Creek Regional Wastewater Treatment Plant (RWWTP). To meet projected growth demands, the new lift station would need to be in service by the end of 2027.
• In February 2024 (Administrative Memorandum No. 24-5993), the Board authorized the preliminary and final engineering services for the design of a new 32 million gallon per day (MGD) Buffalo Creek Lift Station No. 2 to convey projected flows to the South Mesquite Creek RWWTP. Electrical equipment on the market currently has long lead times. Both the specified generator and switchboard have an estimated delivery lead time of nearly 2 years.
• In July 2025 (Administrative Memorandum No. 25-6159), the Board authorized the early electrical equipment procurement package in advance of this main construction package of the lift station. The purpose was to procure the electrical equipment months prior to the main construction package award to support the project's substantial completion by November 2027.
PROJECT COMPONENTS
• New generator and switchboard
• New 32 MGD capacity lift station on the existing Buffalo Creek Lift Station site
