The plant serves a population of approximately 1,856 residents, operating as part of the region's water infrastructure. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 700.30 units and an average daily discharge of 643.52 units, the plant operates efficiently within its capacity. Under the U.S. Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that drain into the Red River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's watershed.

The plant discharges into local streams that flow into the Red River, a major tributary of the Mississippi River. The Mississippi River carries water to the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. Advanced treatment at this plant reduces nutrient loads, helping to mitigate downstream eutrophication and protect aquatic life in the river basin.
