Tittabawassee Township STP - Saginaw County, Michigan Wastewater Treatment Plant

Tittabawassee Township STP is a wastewater treatment facility located in Tittabawassee Township, Saginaw County, Michigan. The plant serves a population of about 7,706 residents, primarily from the local community and the Saginaw Correctional Facility. As a municipal treatment plant in the Great Lakes region, it plays a key role in managing wastewater for this inland community. The plant's designed capacity is 1.00 million gallons per day, indicating a small to medium-scale facility. Under the US Clean Water Act, plants of this size are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). These permits set effluent limits for biochemical oxygen demand, total suspended solids, and other parameters to protect water quality. The treated effluent is discharged to a local waterway within the Saginaw River watershed, which flows into Saginaw Bay and ultimately Lake Huron. This watershed supports diverse aquatic life and is important for regional recreation and fisheries. The plant's operation helps protect downstream water quality in the Great Lakes ecosystem.

The plant discharges into a tributary of the Saginaw River, which flows into Saginaw Bay, a shallow bay of Lake Huron. The Saginaw River watershed drains a large agricultural and industrial region in central Michigan. The bay supports important fish spawning and migratory bird habitats. Protecting water quality in this watershed is critical for the health of Lake Huron and the broader Great Lakes ecosystem.
