The plant discharges into a tributary of the Big Blue River, which flows into the Missouri River and ultimately the Mississippi River. This watershed is part of the Mississippi River basin, one of the largest in North America. The surrounding area is predominantly agricultural, and the receiving waters support diverse aquatic life and are used for irrigation. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems.
