BACKGROUND
GLWA's Sewer Conveyance System has approximately 130 miles of trunk sewers and 51 miles of interceptors. The Connors Creek Sewer System (CCSS) is an extremely large, combined sewer system located in GLWA's East Sewer District. The pipeline consists of five different configurations totaling approximately 8 miles in length. The circular pipe segments range from 24" to 13'-6" diameter between 8 Mile Road and 7 Mile Road. An arch shaped pipe approximately 22' wide and 17' high traverses the Mt. Olivet Cemetery and Coleman Young Airport. A 12' wide x 17'-6" tall double box shape carries flow past I-94 and transitions to 3 - 12' wide x 17'-6' tall conduits from Warren Avenue to East Jefferson. Between Jefferson and the Detroit River, two similar triple barrel conduits receive additional flow from the Connors and Freud Pump Stations to the Connors CSO facility. Much of the sewer was constructed in the 1920s.
