The Lower and Middle River Des Peres (LMRDP) CSO Storage Tunnel Dewatering Pump Station (DPS) will receive all the flow entering the LMRDP CSO Storage Tunnel. The DPS peak design flow is 100 MGD and will pump either to the Lemay Wastewater Treatment Plant (WWTP) or the Enhanced High Rate Clarification (EHRC) facility. The DPS will operate only during or after a weather event that requires the use of the storage tunnel. The bar screen will be located upstream of the DPS to prevent large debris from damaging the pumps.
Proposed Lemay Pump Station No. 3 is a wet-pit/dry-pit station with a firm capacity of 15MGD. Lemay No. 3 Pump Station will accept the flows from the Jefferson Barracks Tunnel and pump to the Lemay WWTF. The new Lemay No. 3 PS will replace the existing pump station. The Lemay No. 3 PS will be the network connection point of all the Intake structures and level sensors in the Jefferson Barracks Tunnel system, therefore control and monitoring of the Tunnel will be consolidated at the Lemay No. 3 PS.
The Maline Creek Local Storage Facility Tunnel (MCT) and Tunnel Dewatering Pump Station (MCTDPS) is designed to relieve the Bissell Point North Interceptor Tunnel during high flows and store 12.5 MGD until the flows recede.
The Jefferson Barracks Tunnel will be responsible for conveying sewage to the Lemay Water Treatment Plant (Lemay WTP) as well as storing potential combined sewer overflow (CSO) and storm sewer overflow (SSO) during a wet weather event.
The Consent Decree requires increasing influent pumping capacity to the Lemay WWTP to 340mgd by December 31, 2015. The District's preferred alternative for providing additional pumping capacity is to design a second (redundant) force main from Lemay Pump Station No. 1 to the Lemay WWTP.
