Berryville STP is a municipal wastewater treatment facility located in Clarke County, Virginia, United States. The plant serves a population of approximately 2,947 residents, operating as part of the region's wastewater infrastructure to manage domestic sewage and protect local water quality. As a US-based plant serving a small community, Berryville STP operates under the regulatory framework of the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For plants of this scale, secondary treatment is typically mandated to reduce organic pollutants and suspended solids before discharge. The plant's treated effluent is discharged into a local waterway within the Potomac River basin, which ultimately flows into the Chesapeake Bay. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life and serving as a critical habitat for migratory birds and fish species.

Berryville STP discharges into a tributary of the Shenandoah River, part of the Potomac River basin that drains into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting a complex ecosystem of fish, crabs, and waterfowl. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making effective treatment essential for downstream ecological health.
