Caseville WWTP - Wastewater Treatment in Caseville Township, Michigan

Caseville WWTP is a municipal wastewater treatment facility located in Caseville Township, Huron County, Michigan. The plant serves a population of 2,219 residents and is situated near the shores of Lake Huron, one of the Great Lakes. As a small agglomeration, it plays a key role in protecting local water quality. The plant has a designed capacity of 1.00 million gallons per day. Under the U.S. Clean Water Act, facilities of this scale are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permit program. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) oversees permitting and compliance for wastewater plants in the state. The treated effluent from Caseville WWTP ultimately discharges into the Lake Huron watershed. Lake Huron supports diverse aquatic life and provides drinking water for millions. The plant's operation is critical to preventing nutrient pollution and protecting the ecological health of this Great Lake.

Caseville WWTP discharges into the Lake Huron basin, part of the Great Lakes system that drains into the St. Lawrence River and eventually the Atlantic Ocean. Lake Huron supports a diverse ecosystem including fish species such as lake trout and walleye, and provides habitat for migratory birds along the shoreline. The plant's location within 50 km of the coast means its effluent can influence nearshore water quality, making nutrient management and pathogen control important for maintaining the lake's ecological balance.
