Project Description: Contractor shall conduct numerous improvements to the Hubbell-Southfield Combined Sewer Overflow (CSO) Facility located in Dearborn, Michigan. Hubbell-Southfield has a 22-million-gallon (MG) storage capacity and a design flow capacity of 2,200 cfs. The facility began operation in 1999 and requires rehabilitation and upgrades to ensure continued reliable treatment of wet weather flows. The facility discharges to the Northwest Interceptor with overflows discharging to the Rouge River.
This project is focused on improving facility treatment reliability, flexibility, operation, maintenance, and safety features at the Hubbell Southfield CSO Facility. This project encompasses improvements to basin flushing, dewatering, disinfection, screening, instrumentation and controls, architectural/HVAC, and electrical, as well as site work and other items. A major upgrade is to replace the existing flushing system used to clean the basin with a more effective system.
