The plant serves a population of approximately 32,000 residents in the surrounding area. As part of the county's wastewater infrastructure, it plays a key role in managing domestic sewage and protecting local water quality. The plant operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For a facility serving a medium-sized agglomeration of this scale, secondary treatment is typically mandated, with additional nutrient removal requirements in sensitive watersheds. The plant's treatment processes are designed to meet state and federal effluent limits. The treated effluent is discharged into the Little River, a tributary of the Savannah River basin. The Savannah River flows southeast into the Atlantic Ocean near Savannah, Georgia. The watershed supports diverse aquatic life and provides drinking water for downstream communities. Proper treatment at this plant helps maintain the ecological health of the river system.

The plant discharges into the Little River, which flows into the Savannah River and ultimately reaches the Atlantic Ocean. The Savannah River basin is ecologically significant, supporting a variety of fish species and providing habitat for migratory birds. The watershed also supplies drinking water to several municipalities, making nutrient and pathogen removal critical for downstream water quality.
