Hubbell-Southfield Facility

The Hubbell-Southfield CSO retention treatment basin (RTB) is one of GLWA’s most active, longest operating CSO facilities and the largest on the Rouge River. Since August 1999, it has been effectively capturing and treating combined sewage through screening, settling and disinfection to meet discharge permit requirements that protect public health.

Located next to the Tournament Players Championship Golf Course in Dearborn, this RTB serves as an example of how our facilities can be good neighbors and blend in with the surrounding environment. The facility features an innovative design that enables three different operational modes within the RTB and prevents resuspension of solids during large storms with high flow rates.
