The plant serves a small population of 1,225 residents, providing secondary treatment to meet state and federal water quality standards.

The treated effluent is discharged into local streams that flow into the Broad River basin, part of the larger Santee River watershed. This region supports diverse aquatic life and provides water for downstream communities. The plant's operations help protect water quality in this ecologically important area.

The plant discharges into tributaries of the Broad River, which flows into the Congaree River and ultimately the Atlantic Ocean via the Santee River. The surrounding Piedmont region features mixed forests and agricultural lands, and the waterways support fish species such as bass and catfish. Protecting water quality is essential for recreational use and downstream ecosystems.
