Document Description
Modifications to Town wastewater treatment plants to comply with new National Pollution Discharge Elimination System (NPDES) permit changes. Changes include modifying the process to reduce effluent total nitrogen below 10 mg/l. Process improvements will take place within the existing fence line at Wastewater Treatment Plant No. 2 at 17501 Highway 4 Discovery Bay, CA 94505. Some minor piping modifications will take place at Plant No. 1 in order to accommodate the work at Plant No. 2. The process changes will not result in an increase of capacity for the Wastewater Treatment Plants. Other improvements include replacing the screen at the headworks, piping and pumping system changes to support the new process, and other maintenance items. The consequesnce for not completing the project would be that the Town would not meet it's new discharge permit requirements for total nitrogen.
