Overview
CAYCE WWTP serves approximately 139,000 people in Cayce, South Carolina, as part of the region's municipal wastewater infrastructure. The plant discharges treated effluent into local waterways that drain toward the Atlantic Ocean.
CAYCE WWTP is a municipal wastewater treatment facility located in Cayce, South Carolina, serving an estimated population of 139,000. The plant is situated in the Congaree River watershed, which flows through the Midlands region of the state. As a large agglomeration, the facility plays a key role in managing wastewater for the greater Columbia metropolitan area. Under the U. S. Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the South Carolina Department of Health and Environmental Control. These permits set effluent limits for biochemical oxygen demand, total suspended solids, and other pollutants to protect water quality. The treated effluent from CAYCE WWTP ultimately discharges into the Congaree River, which joins the Wateree River to form the Santee River. The Santee River flows into the Atlantic Ocean near Georgetown, South Carolina. The downstream environment includes ecologically sensitive areas such as the Congaree National Park, which supports diverse aquatic life and floodplain forests.
Environmental context
CAYCE WWTP discharges into the Congaree River, a major tributary of the Santee River system that drains into the Atlantic Ocean. The Congaree River supports a rich aquatic ecosystem, including fish species such as striped bass and American shad, and its floodplain forests are among the most diverse in North America. The plant's operations are critical to maintaining water quality in this ecologically significant watershed.
