Totopotomoy WWTP - Hanover County, Virginia Wastewater Treatment Plant

Totopotomoy WWTP is a municipal wastewater treatment facility located in Hanover County, Virginia, serving a population of approximately 46,000 residents. The plant is situated in the eastern United States, within the Chesapeake Bay watershed, and plays a key role in managing wastewater from the surrounding suburban and rural areas. As a facility serving a medium-sized agglomeration, the plant is subject to the U.S. Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Virginia Department of Environmental Quality. Plants of this scale typically employ secondary or advanced treatment to meet permit limits for biochemical oxygen demand, total suspended solids, and nutrients. The treated effluent is discharged into Totopotomoy Creek, which flows into the Pamunkey River, a major tributary of the York River. The York River empties into the Chesapeake Bay, the largest estuary in the United States. The plant's operations are critical for protecting water quality in this ecologically sensitive watershed, which supports diverse aquatic life and important fisheries.

Totopotomoy WWTP discharges into Totopotomoy Creek, a tributary of the Pamunkey River, which flows into the York River and ultimately the Chesapeake Bay. The Chesapeake Bay is a large, productive estuary that supports diverse aquatic life, including blue crabs, oysters, and striped bass. Nutrient pollution from wastewater and other sources has historically caused eutrophication and hypoxia in the bay, making effective nutrient removal at treatment plants essential for ecosystem health.
