STEWARTVILLE WWTP - Stewartville, Minnesota Wastewater Treatment Plant

STEWARTVILLE WWTP is a municipal wastewater treatment facility located at 810 20th Street Northeast in Stewartville, Minnesota. Serving a population of about 6,000, the plant is part of the city's infrastructure managed under the U.S. Clean Water Act framework. As a plant serving a small agglomeration, it is expected to meet secondary treatment standards under the National Pollutant Discharge Elimination System (NPDES) permitting program. Typical plants of this scale in Minnesota employ activated sludge or lagoon systems to achieve required effluent limits. The treated effluent from the plant enters the local waterway, which flows into the Root River and eventually the Upper Mississippi River. This region supports diverse aquatic life and is part of the Driftless Area, known for its unique geology and cold-water streams. The plant's discharge is regulated to protect downstream water quality and ecological health.

The plant discharges into a tributary of the Root River, which flows into the Upper Mississippi River. The Mississippi River is a major migratory corridor for birds and fish, and the Driftless Area's spring-fed streams support sensitive species like brook trout. The plant's effluent must meet state and federal standards to protect these downstream ecosystems.
