North Texas Municipal Water District (NTMWD) serves 1.7 million customers by operating one water treatment plant and four regional wastewater treatment plants including the Wilson Creek Regional Wastewater Treatment Plant (RWWTP). This facility discharges into Lake Lavon, which also serves as the District's water supply. With continued growth of the service area and the increased challenge of wet weather flow management, NTMWD evaluated several alternatives and selected to upgrade and expand the Wilson Creek RWWTP. One key characteristic of the adopted alternative is the incorporation of dual-purpose components to provide both advanced treatment of dry weather flows using a high-rate clarification process (Actiflo™), as well as biological treatment of all wet weather flows by converting the high-rate system into a biologically and chemically enhanced mode (BioActiflo™).
