Middle River STP - Augusta County, Virginia Wastewater Treatment Plant

Middle River STP is a municipal wastewater treatment facility located in Augusta County, Virginia, serving a population of around 36,328. The plant is situated inland, away from coastal areas, and its operations are integral to managing wastewater in the Shenandoah Valley region. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the U.S. Clean Water Act, enforced through National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality. These permits set limits on effluent quality to protect receiving waters. The treated effluent from Middle River STP likely discharges into a tributary of the Middle River, which flows into the South Fork Shenandoah River, part of the Potomac River basin. This watershed ultimately drains into the Chesapeake Bay, a vital estuary supporting diverse aquatic life and commercial fisheries.

The plant's discharge enters the Middle River, a tributary of the South Fork Shenandoah River, which flows into the Potomac River and eventually the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient and sediment pollution from wastewater can impact water quality and ecosystem health in the bay.
