Greensboro South WPCP - Advanced Wastewater Treatment in Greensboro, Georgia

Greensboro South WPCP is an advanced wastewater treatment facility located on South Main Street in Greensboro, Greene County, Georgia. The plant serves a population of approximately 2,025 residents, reflecting its role as a small municipal treatment system within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,785.40 m³/day and an actual discharge volume of 946.35 m³/day, the facility operates well below its capacity. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Georgia Environmental Protection Division, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local water body, ultimately contributing to the Oconee River watershed, which flows into Lake Oconee and then the Altamaha River before reaching the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into a tributary of the Oconee River, which flows into Lake Oconee, a major reservoir on the Oconee River. From there, water enters the Altamaha River, one of Georgia's largest rivers, which empties into the Atlantic Ocean near Darien. The Altamaha River basin supports diverse aquatic life, including several species of freshwater mussels and fish, and provides critical habitat for migratory birds. Advanced treatment at the plant helps reduce nutrient loading, protecting downstream water quality and ecological health.
