Philippi Tygart Glen WWTP - Secondary Treatment Plant in Philippi, West Virginia

Philippi Tygart Glen WWTP is a municipal wastewater treatment facility located in Philippi, Barbour County, West Virginia. The plant serves a small population of 55 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 98.42 thousand cubic meters per year and currently treats 75.71 thousand cubic meters annually. Under the U.S. Clean Water Act, facilities of this scale are typically regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Secondary treatment is the minimum standard for municipal wastewater plants in the United States. The treated effluent is discharged into a receiving water body within the Tygart Valley River watershed, which flows into the Monongahela River and eventually the Ohio River. This drainage system supports diverse aquatic life and provides water resources for communities downstream. The plant's operation helps maintain local water quality in this Appalachian region.

The plant discharges into a tributary of the Tygart Valley River, part of the Monongahela River basin that drains into the Ohio River. This watershed supports a variety of freshwater species and is used for recreation and drinking water supply. The surrounding Appalachian terrain features forested hills and valleys, with the plant's effluent contributing to base flow in the river system.
