DILLWYN STP Wastewater Treatment Plant, Dillwyn, Virginia

DILLWYN STP is a municipal wastewater treatment facility located in Dillwyn, Buckingham County, Virginia. The plant serves a small community of approximately 517 residents, providing secondary treatment to manage domestic wastewater. As a small-scale facility, it plays a key role in local sanitation and water quality protection. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater discharges. With a designed capacity of 378.54 thousand cubic meters per year and an annual discharge volume of 264.98 thousand cubic meters, the facility operates below its capacity, indicating room for future growth or seasonal variability. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local waterway, contributing to the James River watershed, which ultimately drains into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and important fisheries. The plant's operations help protect downstream water quality and the bay's ecosystem.

DILLWYN STP discharges into a tributary of the James River, which flows into the Chesapeake Bay, the largest estuary in the United States. The bay supports a rich ecosystem including blue crabs, oysters, and migratory fish. The plant's secondary treatment reduces nutrient loads, helping to mitigate eutrophication and hypoxia in the bay, which are critical concerns for this sensitive water body.
