The treated effluent is discharged into a local waterway that drains into the Arkansas River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream aquatic ecosystems, including the Mississippi River's diverse fish and wildlife habitats.

The plant discharges into a tributary of the Arkansas River, which flows into the Mississippi River and then the Gulf of Mexico. The Arkansas River basin supports diverse aquatic life, including numerous fish species and migratory birds. The plant's secondary treatment helps reduce nutrient loading, which is important for preventing eutrophication in downstream waters.
