CADWELL WPCP - Advanced Wastewater Treatment Plant in Cadwell, Georgia

CADWELL WPCP is a municipal wastewater treatment facility located on Coleman Street in Cadwell, Laurens County, Georgia. The plant serves a small community of approximately 263 residents, reflecting its role in providing essential sanitation services to a rural area in the southeastern United States. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the US Clean Water Act. With a design capacity of 189.27 m³/day and a current discharge volume of 75.71 m³/day, the facility operates well within its capacity. As a US plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body, ultimately contributing to the Oconee River basin and the Altamaha River system, which flows into the Atlantic Ocean. The advanced treatment level helps minimize nutrient and pollutant loads, supporting the ecological health of downstream waters and the coastal environment.

CADWELL WPCP discharges treated wastewater into a local stream that drains into the Oconee River basin, part of the larger Altamaha River watershed. The Altamaha River is one of the largest free-flowing rivers on the US East Coast, supporting diverse aquatic life including several species of freshwater mussels and fish. The advanced treatment level reduces nutrient pollution, which is critical for preventing eutrophication in downstream estuaries and coastal waters.
