Saginaw Twp STP - Saginaw Charter Township, Michigan Wastewater Treatment Plant

Saginaw Twp STP is a municipal wastewater treatment facility located in Saginaw Charter Township, Michigan, serving a population of about 41,031. The plant is situated in the Saginaw Bay watershed, part of the larger Lake Huron basin, and plays a key role in protecting local water quality. As a facility serving a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the US Clean Water Act. NPDES permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) govern discharge limits to ensure compliance with water quality standards. The plant's designed capacity is 1.00 million gallons per day, reflecting its scale. The treated effluent from Saginaw Twp STP ultimately discharges into the Saginaw River system, which flows into Saginaw Bay and then Lake Huron. This water body supports diverse aquatic life and is an important recreational and ecological resource in the Great Lakes region. The plant's operations help reduce nutrient and pollutant loads, contributing to the health of the downstream ecosystem.

The plant discharges into the Saginaw River watershed, which drains into Saginaw Bay, a shallow, nutrient-rich embayment of Lake Huron. Saginaw Bay supports important fisheries, including walleye and perch, and provides habitat for migratory waterfowl. The bay has historically experienced eutrophication issues due to nutrient inputs, making effective wastewater treatment critical for maintaining water quality and ecological balance in the Great Lakes system.
