Sheffield Acres Flatwoods Collection System - Wise County, Virginia Wastewater Treatment

Sheffield Acres Flatwoods Collection System is a wastewater treatment facility located in Wise County, Virginia, serving a small population of 625 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 151.42 million gallons per day and a discharge volume matching that figure, the facility is operating at full capacity. As a small agglomeration, it meets the typical treatment requirements for its size under the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent is discharged into local streams that drain into the Tennessee River watershed, ultimately reaching the Ohio River and Mississippi River. This inland location supports aquatic life in the Appalachian region, and the plant's secondary treatment helps protect water quality in this ecologically sensitive area.

The plant discharges into local streams within the Tennessee River basin, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. The Appalachian region's watershed supports diverse aquatic species and provides important habitat for fish and macroinvertebrates. Secondary treatment helps reduce nutrient loading and organic pollution, protecting downstream ecosystems.
