The facility serves a population of approximately 1,841 residents, classifying it as a small-scale treatment plant under U.S. regulatory frameworks. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 1,324.89 volume units and an average discharge volume of 787.37 volume units, the plant operates below its maximum capacity, indicating room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Yadkin-Pee Dee River basin, supporting downstream aquatic ecosystems. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, ensuring compliance with water quality standards.

The plant discharges into a tributary of the Yadkin River, which flows into the Pee Dee River and eventually reaches the Atlantic Ocean near Georgetown, South Carolina. The Yadkin-Pee Dee basin supports diverse aquatic life, including several fish species and freshwater mussels. The plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids.
