The plant discharges into a local stream that is part of the Missouri River watershed. The Missouri River flows into the Mississippi River, which drains into the Gulf of Mexico. The watershed supports diverse aquatic life and is important for regional water quality. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting downstream ecosystems from eutrophication and oxygen depletion.
