The plant discharges into the Minnesota River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports diverse aquatic species and is an important migratory corridor for birds. The region's agricultural land use can contribute nutrient runoff, making the plant's secondary treatment role critical for reducing pollutant loads.
