CHATHAM STP Wastewater Treatment Plant, Pittsylvania County, Virginia

CHATHAM STP is a wastewater treatment plant located in Pittsylvania County, Virginia, serving a population of 2,163. The facility is part of the region's municipal wastewater infrastructure, treating domestic wastewater from the local community. As a plant serving fewer than 10,000 people, it falls under the U.S. Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permitting program. The Virginia Department of Environmental Quality (DEQ) issues permits for such facilities, typically requiring secondary treatment as a minimum standard. Regulatory compliance ensures appropriate treatment for the population served. The treated effluent is discharged to a local waterway, likely a tributary of the Dan River or Roanoke River basin, which ultimately flows into the Atlantic Ocean via the Albemarle Sound. The plant plays a role in protecting downstream water quality and aquatic ecosystems in the Piedmont region of Virginia.

The plant discharges to a local stream within the Dan River watershed, which flows into the Roanoke River and then to the Albemarle Sound in North Carolina. This region supports diverse aquatic life, including fish species such as smallmouth bass and sunfish. The watershed is also important for recreational activities and drinking water supplies downstream.
