The plant discharges into local streams that flow into the Marais des Cygnes River, a tributary of the Missouri River, which eventually reaches the Mississippi River and the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, mitigating impacts on downstream ecosystems.
