Holston Regional WWTP and Coll Sys is a municipal wastewater treatment facility located in Scott County, Virginia, United States. The plant serves a population of approximately 5,393 people, reflecting a small to medium-sized agglomeration typical of rural Appalachian communities. Its location in the mountainous terrain of southwestern Virginia places it within the Tennessee River watershed. As a US facility, the plant operates under the Clean Water Act, administered by the Virginia Department of Environmental Quality through the National Pollutant Discharge Elimination System (NPDES) permit program. For a plant serving around 5,000 people, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids before discharge. Regulatory compliance is expected under state and federal guidelines. The treated effluent likely discharges into a tributary of the Holston River, which flows into the Tennessee River, then the Ohio River, and ultimately the Mississippi River to the Gulf of Mexico. This watershed supports diverse aquatic life and is an important ecological corridor in the Appalachian region. The plant's operations contribute to protecting local water quality in this sensitive headwater environment.
