Its operations help protect the region's aquatic ecosystems and support water quality in the downstream environment.

The plant discharges into local streams that flow into the Missouri River, a major tributary of the Mississippi River system. This watershed supports diverse aquatic life and provides habitat for fish and migratory birds. The secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in the Missouri River and the Gulf of Mexico.
