Overview
Chapaton Retention Treatment Basin is a projected wastewater facility in Saint Clair Shores, Michigan, serving approximately 47,159 people. It is located within 50 km of the Lake Erie coastline.
Chapaton Retention Treatment Basin is a projected wastewater facility located in Saint Clair Shores, Michigan, within the Great Lakes region. The plant is designed to serve a population of approximately 47,159, placing it in the medium-agglomeration category under US regulatory frameworks. As a projected facility, specific treatment processes are not yet defined. However, US plants of this scale typically operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). These permits enforce secondary treatment standards and may require additional controls for discharges into sensitive waters like the Great Lakes. The facility's discharge is expected to enter the Lake St. Clair system, which connects to the Detroit River and ultimately Lake Erie. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's location near the coast underscores the importance of advanced treatment to protect the Great Lakes ecosystem.
Environmental context
The plant is situated in the Lake St. Clair watershed, part of the Great Lakes Basin. Discharge from the facility would flow into Lake St. Clair, then through the Detroit River to Lake Erie. This region supports diverse aquatic species and is a critical migratory corridor for fish. Protecting water quality is essential due to the lakes' role as a drinking water source and recreational resource.
