The plant's treated effluent discharges into local waterways within the Mississippi River basin. The receiving waters eventually flow into the Mississippi River and then to the Gulf of Mexico, supporting diverse aquatic life and contributing to the region's ecological health.

The plant discharges into tributaries of the Mississippi River, which drains into the Gulf of Mexico. This watershed supports a variety of aquatic species and is part of a larger ecosystem that includes wetlands and floodplains. Proper wastewater treatment is essential to prevent nutrient pollution that can contribute to hypoxic zones in the Gulf.
