BLISSFIELD STP - Blissfield Township, Michigan Wastewater Treatment Plant

BLISSFIELD STP is a municipal wastewater treatment plant located in Blissfield Township, Lenawee County, Michigan. It serves a population of about 3,223 people, classifying it as a small community facility within the state's wastewater infrastructure. As a U.S. plant, it 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). Plants of this scale typically employ secondary treatment to meet federal and state standards. The plant's treated effluent discharges into the River Raisin watershed, which flows into Lake Erie, part of the Great Lakes system. This makes the plant's operations critical for protecting downstream aquatic habitats and the broader Lake Erie ecosystem, which supports diverse fish populations and recreational activities.

The plant discharges into the River Raisin watershed, which drains into western Lake Erie. Lake Erie is the shallowest of the Great Lakes and supports a rich ecosystem, including walleye and perch fisheries, as well as migratory bird routes. The watershed is agriculturally intensive, and nutrient management is a key concern to prevent algal blooms in the lake.
