DUNGANNON STP - Secondary Wastewater Treatment in Dungannon, Virginia

DUNGANNON STP is a municipal wastewater treatment facility located in Dungannon, Scott County, Virginia. Serving a small population of 354 residents, the plant provides secondary treatment to meet state and federal water quality standards under the U.S. Clean Water Act. The plant operates with a designed capacity of 151.42 megaliters per year and discharges a corresponding volume. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids, ensuring effluent quality suitable for discharge into the local watershed. The treated effluent enters the Tennessee River basin, which drains into the Ohio River and ultimately the Mississippi River. This system supports diverse aquatic life and provides water resources for communities downstream. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall health of the regional river network.

The plant discharges into the Tennessee River basin, a major tributary of the Ohio River that flows into the Mississippi River and the Gulf of Mexico. The watershed supports diverse aquatic ecosystems, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's secondary treatment helps protect water quality in this ecologically significant river system.
