Chase City Regional STP - Secondary Wastewater Treatment in Chase City, Virginia

Chase City Regional STP is a municipal wastewater treatment facility located in Chase City, Mecklenburg County, Virginia, United States. The plant serves a population of approximately 2,438 residents and operates as a secondary treatment facility, which is the standard level required under the U.S. Clean Water Act for municipal wastewater treatment. The plant has a designed capacity of 2,271.24 thousand cubic meters per year and currently discharges 757.08 thousand cubic meters annually, indicating operational capacity well within its design limits. As a secondary treatment plant, it employs biological processes to reduce organic matter and suspended solids, meeting the effluent standards set by the Virginia Department of Environmental Quality under the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent from the plant is discharged into a local water body that ultimately drains into the Roanoke River Basin, which flows into Albemarle Sound and the Atlantic Ocean. The plant plays a key role in protecting the water quality of the region's streams and rivers, supporting aquatic life and downstream ecosystems in the Chesapeake Bay watershed.

The plant discharges into a tributary of the Roanoke River, which flows into the Albemarle Sound and then the Atlantic Ocean. The Roanoke River Basin supports diverse aquatic habitats, including important spawning grounds for anadromous fish species. The plant's secondary treatment helps reduce nutrient loads that could contribute to eutrophication in downstream estuaries.
