Stonewall Jackson Lake State Park WWTP - Lewis County, West Virginia Secondary Treatment

Stonewall Jackson Lake State Park Wastewater Treatment Plant (WWTP) is located in Lewis County, West Virginia, United States. The plant serves a population of about 4,535 people, primarily from the state park and surrounding area. As a secondary treatment facility, it provides biological treatment to remove organic matter and suspended solids. The plant has a designed capacity of 378.54 cubic meters per day and discharges a similar volume of treated effluent. Under the U.S. Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the West Virginia Department of Environmental Protection, which set limits on effluent quality to protect receiving waters. The treated wastewater from Stonewall Jackson Lake SP WWTP is discharged into the local watershed, which drains into the West Fork River, a tributary of the Monongahela River. The Monongahela River flows northward to join the Allegheny River at Pittsburgh, forming the Ohio River. This waterway supports diverse aquatic life and is used for recreation and drinking water supply downstream.

The plant discharges into the West Fork River watershed, which flows into the Monongahela River and eventually the Ohio River. This river system supports a variety of fish and wildlife, including species of recreational and ecological importance. The region's forested landscape and moderate climate contribute to seasonal flow variations that affect dilution and assimilative capacity of the receiving waters.
