Appomattox STP No II Wastewater Treatment Plant, Appomattox, Virginia

Appomattox STP No II is a municipal wastewater treatment facility located on Ethel Street in Appomattox, Virginia. The plant serves a small population of 604 residents, reflecting the rural character of the Appomattox County area. It operates as a secondary treatment facility, which is the standard level required by the US Clean Water Act for most municipal plants. The plant has a designed capacity of 189.27 megaliters per year and discharges a corresponding volume of treated wastewater. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Virginia Department of Environmental Quality. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The treated effluent from Appomattox STP No II ultimately enters the local watershed, which drains into the Appomattox River, a tributary of the James River. The James River flows into the Chesapeake Bay, the largest estuary in the United States. The plant's discharge contributes to the nutrient and pollutant load in the bay, making its treatment performance important for downstream water quality.

The plant discharges into the Appomattox River basin, which flows into the James River and then the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia in the bay, so secondary treatment helps reduce these impacts.
