QUINCY LAGOON Wastewater Treatment Plant - Quincy Township, Michigan

QUINCY LAGOON is a municipal wastewater treatment facility located in Quincy Township, Branch County, Michigan. It serves a population of approximately 1,700 residents, providing essential sanitation services for this rural community in the southern part of the state. The plant employs secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 757.08 cubic meters per day and a current discharge volume of 681.37 cubic meters per day, the facility operates below its capacity, indicating room for future growth. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) to ensure compliance with water quality standards. The treated effluent from QUINCY LAGOON ultimately drains into the St. Joseph River watershed, which flows westward through Michigan and Indiana before emptying into Lake Michigan. This connection to the Great Lakes system underscores the plant's role in protecting downstream aquatic habitats and the broader Lake Michigan ecosystem.

QUINCY LAGOON discharges into local streams that are part of the St. Joseph River basin, which flows into Lake Michigan. The St. Joseph River supports diverse aquatic life, including fish species such as walleye and smallmouth bass, and provides important habitat for migratory waterfowl. The plant's secondary treatment helps reduce nutrient loading and protects the ecological health of this inland watershed.
