VIRGILINA STP - Secondary Wastewater Treatment Plant in Virgilina, Virginia

VIRGILINA STP is a municipal wastewater treatment facility located in Virgilina, a small town in Halifax County, Virginia. The plant serves a population of 383 people, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment as the minimum standard for municipal wastewater plants. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 132.49 million gallons per day and an actual discharge volume of 79.49 million gallons per day, the plant operates below its capacity. This suggests adequate headroom for current demand. The treated effluent is discharged into a local water body, which ultimately drains into the Roanoke River Basin and then to the Albemarle Sound. The plant's location inland and away from the coast reduces direct marine impact, but its discharge contributes to the overall water quality of the watershed, supporting aquatic life and downstream ecosystems.

The plant discharges into a local stream that is part of the Roanoke River Basin, which flows into the Albemarle Sound in North Carolina. This watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in a region where agriculture and forestry are prevalent land uses.
