WEYERS CAVE STP - Secondary Wastewater Treatment in Augusta County, Virginia

WEYERS CAVE STP is a municipal wastewater treatment facility located in Augusta County, Virginia, within the Shenandoah Valley region. The plant serves a small community of approximately 1,845 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 3,785.40 m³/day and an actual discharge volume of 946.35 m³/day, the facility operates well below its capacity, indicating room for future growth. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality, which set effluent limits to protect water quality. The treated effluent from WEYERS CAVE STP is discharged to a local stream that ultimately flows into the Shenandoah River, a tributary of the Potomac River and the Chesapeake Bay. The plant plays a key role in protecting the Shenandoah River's water quality, which supports diverse aquatic life and recreational uses. Its location in the Shenandoah Valley, a region known for agriculture and tourism, underscores the importance of effective wastewater management.

The plant discharges into a small tributary of the Shenandoah River, which flows northward to join the Potomac River and eventually the Chesapeake Bay. The Shenandoah River watershed supports diverse fish populations, including smallmouth bass and native brook trout, and is a vital ecological corridor in the Appalachian region. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in the Chesapeake Bay.
