Hillsboro WWTP - Secondary Treatment Plant in Hillsboro, West Virginia

Hillsboro WWTP is a municipal wastewater treatment plant located in Hillsboro, Pocahontas County, West Virginia, United States. The facility serves a small population of 250 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. It has a designed capacity of 189.27 cubic meters per day and discharges a similar volume daily. As a small facility in West Virginia, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program administered by the West Virginia Department of Environmental Protection. The treated effluent is discharged into a local waterway that ultimately drains into the Greenbrier River, a tributary of the New River, which flows into the Kanawha River and then the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities.

The plant discharges into a small stream that feeds the Greenbrier River, part of the Ohio River basin. The Greenbrier River is known for its clean water and supports a variety of fish species, including trout. Downstream, the New River and Kanawha River provide habitat for mussels and other aquatic organisms. The plant's secondary treatment helps protect this sensitive watershed from nutrient pollution.
