Great Valley T FairView SubdSD4 Wastewater Treatment Plant, Peth, New York

Great Valley T FairView SubdSD4 is a municipal wastewater treatment plant located in Peth, a hamlet within the Town of Great Valley, Cattaraugus County, New York. The plant serves a small population of 50 residents, reflecting its role in a rural community in the Allegheny Plateau region. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 15.14 units and a discharge volume matching that figure, the facility operates at full capacity. Under the U.S. Clean Water Act, such plants are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. The treated effluent is discharged into a local waterway, likely a tributary of the Allegheny River, which flows south into the Ohio River and eventually the Mississippi River. The plant's operation helps protect downstream aquatic habitats in the Allegheny River basin, which supports diverse fish species and recreational uses.

The plant discharges into a small stream within the Allegheny River watershed. The Allegheny River flows through western New York and Pennsylvania before joining the Ohio River. This region features forested hills and coldwater streams that support trout populations. The plant's secondary treatment helps maintain water quality in this sensitive headwater environment.
