NICKLESVILLE STP - Scott County, Virginia Wastewater Treatment Plant

NICKLESVILLE STP is a municipal wastewater treatment plant located in Scott County, Virginia, United States. The facility serves a small population of 650 residents and operates as part of the region's wastewater infrastructure. It is situated inland, away from coastal areas, and treats wastewater for the local community. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 264.98 million gallons per year and currently discharges 124.92 million gallons per year, indicating operational capacity below its design limit. The treated effluent is discharged into local waterways that ultimately drain into the Tennessee River basin. The plant plays a role in protecting downstream water quality in the region's rivers and streams, which support aquatic life and recreational uses. Its operation helps maintain compliance with federal and state water quality standards under the National Pollutant Discharge Elimination System (NPDES) permit program.

The plant discharges into local streams that are part of the Tennessee River watershed, which flows into the Ohio River and eventually the Mississippi River. The region's waterways support diverse aquatic ecosystems, including fish and macroinvertebrate communities. Proper treatment is essential to prevent nutrient pollution and maintain water quality for downstream uses such as drinking water supply and recreation.
