The treated effluent from Red Wing Municipal WWTP discharges into the Mississippi River, a major waterway that flows southward to the Gulf of Mexico. The Upper Mississippi River supports diverse aquatic life, including fish species such as walleye and northern pike, and provides habitat for migratory birds. Proper treatment helps protect downstream water quality and the ecological health of the river system.

The plant discharges into the Mississippi River, which flows through the Upper Mississippi River Basin and ultimately reaches the Gulf of Mexico. This section of the river supports a variety of fish and wildlife, including freshwater mussels and waterfowl. The watershed is influenced by agricultural runoff and urban development, making effective wastewater treatment critical for maintaining water quality and preventing nutrient enrichment downstream.
