Stony Creek STP - Secondary Treatment Plant in Sussex County, Virginia

Stony Creek STP is a municipal wastewater treatment plant located in Sussex County, Virginia, serving a small population of 479 residents. The facility operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal plants discharging to surface waters. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 189.27 megaliters per year and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it is subject to EPA NPDES permitting administered by the Virginia Department of Environmental Quality. The treated effluent is discharged to local streams that drain into the Nottoway River, a tributary of the Chowan River, which ultimately flows into Albemarle Sound and the Atlantic Ocean. The plant plays a role in protecting water quality in this coastal plain watershed, which supports diverse aquatic life and recreational uses.
