New Haven WWTP - Secondary Treatment Plant in West Virginia

New Haven WWTP is a municipal wastewater treatment facility located in New Haven, Mason County, West Virginia. The plant serves a population of approximately 2,623 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1,514.16 thousand cubic meters, the plant currently treats an annual discharge volume of 719.23 thousand cubic meters, indicating it operates below its design capacity. The treated effluent is discharged into a local waterway that ultimately drains into the Ohio River, a major tributary of the Mississippi River system. This downstream connection highlights the plant's role in protecting water quality in the Ohio River basin, which supports diverse aquatic life and provides drinking water for millions.

The plant discharges into a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish and wildlife species, and the plant's secondary treatment helps reduce nutrient and pollutant loads that could contribute to downstream eutrophication and hypoxia in the Gulf.
