The plant's designed capacity of 264.98 units indicates room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Arkansas River basin. This watershed supports diverse aquatic life and provides water for downstream communities. Advanced treatment helps minimize nutrient loading and protects the ecological health of the receiving waters.

The plant discharges into a tributary of the Arkansas River, which flows through Arkansas and eventually joins the Mississippi River. The Arkansas River basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Advanced treatment at this plant helps reduce nutrient pollution, which can cause algal blooms and degrade water quality in downstream lakes and rivers.
