The existing Lakewood Lift Station at Lakewood Park, located in Saint Charles, Miss., is an emergency lift station that operates only during high flows. Even with the station operating, some area manholes were still experiencing overflows in times of exceedingly high flow. Public Water Supply District 2 determined that the best solution would be to construct a new collector station and an additional sanitary sewer overflow tank to take flow away from the under-lake sewer system where the existing lines were below capacity, alleviating the current overflow problems.
As part of the improvements for the Lakewood Lift Station, DuroMaxx steel reinforced polyethylene (SRPE) was chosen for the design of the inline storage of sanitary sewerage required for the project. The project engineering design team at Hanson Professional Services Inc. had previously used DuroMaxx SRPE on a storm water detention project in Springfield, Ill., and wanted to use it for this sanitary application. These vessels are both durable and watertight, providing a cost-effective way as a storage solution for this particular project. The DuroMaxx SRPE sanitary sewer overflow (SSO) system was designed as a 96-ln ft long, 72-in. in diameter, single barrel inline tank.
Having had previous experience with DuroMaxx SRPE as a tank solution, the design team at Hanson knew it would be a good solution to capture sanitary effluent in this application as well. DuroMaxx SRPE combines the strength of steel with the durability of plastic, resulting in a strong and durable pipe. Capable of a 120-in. diameter and a 30-psi welded coupler (WC) joint, it is an ideal solution for CSO and SSO storage.
