STEWART WWTF - Round Grove Township, Minnesota Wastewater Treatment Plant

STEWART WWTF is a municipal wastewater treatment facility located in Round Grove Township, McLeod County, Minnesota, United States. The plant serves a small population of 572 residents, reflecting its role in a rural community. It is situated inland, far from coastal areas, and operates under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required by the US Environmental Protection Agency (EPA) for municipal wastewater facilities. With a designed capacity of 431.54 units and a current discharge volume of 386.11 units, the plant operates below its capacity, indicating adequate headroom for current demand. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body, likely a tributary of the Minnesota River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems and support the ecological health of the region's waterways.

The plant discharges into a local watercourse within the Minnesota River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The downstream environment supports diverse aquatic life and is part of a major migratory corridor for birds and fish. The plant's secondary treatment reduces organic pollutants and suspended solids, mitigating eutrophication risks in receiving waters.
