Haysi Sewerage System - Secondary Wastewater Treatment in Haysi, Virginia

The Haysi Sewerage System is a municipal wastewater treatment facility located in Haysi, Dickenson County, Virginia. Serving a population of approximately 1,950, this plant provides secondary treatment to domestic wastewater from the community. The facility operates under the regulatory framework of the U.S. Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality. The plant has a designed capacity of 378.54 cubic meters per day and currently treats an average daily flow of 302.83 cubic meters, indicating operational headroom. Secondary treatment, which includes biological processes to reduce organic matter and suspended solids, is the standard for plants of this scale in the United States. The facility's discharge volume and treatment level are consistent with requirements for small communities in rural Appalachian settings. The treated effluent is discharged into nearby streams that drain into the Upper Tennessee River system, ultimately reaching the Mississippi River and the Gulf of Mexico. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations help protect local water quality in a region characterized by mountainous terrain and coal mining heritage.

The Haysi Sewerage System discharges into tributaries of the Upper Tennessee River, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed supports diverse aquatic species, including several endemic fish and mussel species. The region's steep slopes and coal mining history make water quality management critical for preventing sedimentation and contamination of downstream habitats.
