CLAY WWTP - Secondary Wastewater Treatment in Clay County, West Virginia

CLAY WWTP is a wastewater treatment facility located in Clay County, West Virginia, United States. It serves a small population of approximately 999 residents, reflecting its role in a rural community. The plant is situated in the Appalachian region, characterized by hilly terrain and numerous small streams. The plant provides secondary treatment, which is the standard biological treatment process required under the US Clean Water Act for municipal facilities. With a designed capacity of 757.08 cubic meters per day and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the West Virginia Department of Environmental Protection, ensuring compliance with effluent limits. The treated effluent from CLAY WWTP is discharged into local receiving waters, likely tributaries of the Elk River or Kanawha River, which ultimately flow into the Ohio River and then the Mississippi River system. This connection to a major river basin underscores the plant's role in protecting downstream water quality and aquatic habitats in the region.
