The primary function of the District is to operate a sewage transportation system servicing Eastpointe, Roseville, St. Clair Shores, Grosse Pointe Woods, Harper Woods, and Grosse Pointe Shores. This sewage transportation system includes approximately 30 miles of sewer, 350 manholes, and 4 pump stations.
Originally designed as a pumping station and sewage treatment plant in 1926, SEMSD Headquarters now serves as an operational base for all facilities. The facility is located near 9 Mile Road and I-94 at 20001 Pleasant Street, St. Clair Shores, MI 48080.
Hoffman Pump Station
Located in a residential neighborhood of northern St. Clair Shores, the Hoffman Pump Station serves as an example of how our facilities can be good neighbors. The facility was constructed in 2001 and utilizes a variable frequency drive pumping system.
Martin Drain Pump Station (Rio Vista)
The Martin Drain Pump Station or Rio Vista Pump Station serves as a pumping facility for permitted and treated combined sewage discharges. Constructed in 1992, the pump station services roughly 9,000 acres of land in Roseville and St. Clair Shores. These permitted and treated discharges are tested to ensure compliance with applicable water quality standards.
Marter Road Booster Station
Transporting sewage from Eastpointe, St. Clair Shores and Roseville, the Marter Road Booster Station was built in 1961 and is located near the Macomb and Wayne County Line. The facility features an innovative design that enables two different operational modes for conveying sewage. The facility was acquired from Wayne County in September of 2018.
Kerby Road Pump Station
Located in Grosse Pointe Farms, the Kerby Road Pump Station is the District’s southernmost facility. Similar to the Martin Drain Pump Station, the Kerby Road Pump Station was constructed in 1992 and transports sewage to Great Lakes Water Authority’s Water Resource Recovery Facility for treatment. The facility was acquired from Wayne County in September of 2018.
Milk River Retention Treatment Basin & Recirculation Station
The Southeast Macomb Sanitary District operates the Milk River Retention Treatment Basin on behalf of the Milk River Intercounty Drain Drainage District. The treatment basin is located in Grosse Pointe Woods and has dramatically improved the water quality of the Milk River since its groundbreaking in 1958. The Milk River Retention Treatment Basin provides combined sewage overflow treatment through screening, settling, storage, sodium hypochlorite disinfection, and aeration. The permitted and treated discharges are tested to ensure compliance with applicable water quality standards.
