Whitney Point V STP - Secondary Wastewater Treatment in Town of Dix, New York

Whitney Point V STP is a municipal wastewater treatment facility located in the Town of Dix, Schuyler County, New York. The plant serves a small population of 1,054 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. As a small-scale facility in rural upstate New York, it plays a key role in protecting local water quality. The plant operates with a designed capacity of 473.18 megaliters per year and discharges a similar volume of treated effluent. Under the US Clean Water Act, facilities of this size are typically regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. Secondary treatment is the standard requirement for municipal plants, ensuring that effluent meets federal guidelines for biochemical oxygen demand and total suspended solids. The treated wastewater from Whitney Point V STP ultimately drains into the Susquehanna River basin, which flows south through Pennsylvania and into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological and economic importance, supporting diverse aquatic life and migratory birds. The plant's operations contribute to the overall health of this watershed by reducing nutrient and pollutant loads.

The plant discharges into local streams that are part of the Susquehanna River watershed, which drains into the Chesapeake Bay. The Chesapeake Bay is a major estuary that supports a rich ecosystem, including blue crabs, oysters, and migratory waterfowl. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia in the bay, making effective treatment critical for downstream environmental health.
