Miller Park to Pershing Detention Basin Sewer Separation Project

The Miller Park to Pershing Detention Basin Sewer Separation Project diverts already separated stormwater to the Pershing Detention Basin. This project included construction of approximately 2,300 feet of 60-inch stormwater conveyance sewer between the basins. Due to topography and utility conflicts, approximately 1,260 feet of the 60-inch pipeline alignment was installed using microtunneling. Modifications to the existing Miller Park outlet structure, construction of a new inlet into the Pershing Detention Basin, and construction of a vegetated swale to direct stormwater runoff from Miller Park to the new conveyance sewer were also included in the project. This project reduces flows in the combined sewer system and reduces the size of required downstream controls. Water quality benefits are achieved from water flows through the Pershing Basin prior to discharge to the Missouri River.
