Its designed capacity is 946.35 thousand gallons per day, with an average discharge volume of 340.69 thousand gallons per day. As a small facility, it is subject to EPA NPDES permitting administered by the Louisiana Department of Environmental Quality. The treated effluent is discharged into local drainage systems that flow into the Red River, a major tributary of the Mississippi River. The Red River basin supports diverse aquatic life and provides water for agriculture and recreation. The plant's operations help maintain the ecological health of this important watershed.

The plant discharges into local waterways that drain into the Red River, which flows south through Louisiana to the Atchafalaya River and ultimately the Gulf of Mexico. The Red River basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this ecologically sensitive region.
