ST CLAIR RIVER SA WWTP - East China Charter Township, Michigan Wastewater Treatment Plant

ST CLAIR RIVER SA WWTP is a municipal wastewater treatment facility located in East China Charter Township, Michigan, United States. The plant serves a population of approximately 9,383 residents and has a designed capacity of 1.00 million gallons per day, reflecting its role in managing local wastewater for this community. As a US-based facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For a plant serving fewer than 10,000 people, secondary treatment is typically required to meet effluent standards before discharge. The plant's treated effluent is discharged into the St. Clair River, which flows southward into Lake St. Clair and then via the Detroit River to Lake Erie. This waterway is part of the Great Lakes Basin, supporting diverse aquatic life and providing drinking water for millions. The plant plays a key role in protecting water quality in this sensitive freshwater ecosystem.

The plant discharges into the St. Clair River, a connecting channel between Lake Huron and Lake St. Clair. The river flows into Lake St. Clair, then through the Detroit River to Lake Erie, forming part of the Great Lakes system. This watershed supports diverse fish populations, including walleye and lake sturgeon, and provides habitat for migratory birds. Protecting water quality here is critical for downstream communities and the ecological health of the Great Lakes.
