Elliston Lafayette STP - Secondary Wastewater Treatment in Lafayette, Virginia

Elliston Lafayette STP is a municipal wastewater treatment facility located at 5187 Enterprise Road in Lafayette, Montgomery County, Virginia. The plant serves a population of approximately 1,600 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The facility provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 946.35 thousand cubic meters per year and an annual discharge volume of 302.83 thousand cubic meters, the plant operates well below its capacity. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Roanoke River watershed. This river system flows into the Albemarle Sound in North Carolina, supporting diverse aquatic life and recreational uses. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall health of the watershed.

The plant discharges into a tributary of the Roanoke River, which flows southeast through Virginia and North Carolina before emptying into the Albemarle Sound. The Roanoke River watershed supports a variety of fish species, including striped bass and American shad, and provides habitat for freshwater mussels. The plant's secondary treatment helps reduce nutrient loading, which is important for preventing eutrophication in downstream estuaries.
