Prattsville T hamlet WWTF and On S - Advanced Wastewater Treatment in Town of Jewett, New York

Prattsville T hamlet WWTF and On S is a municipal wastewater treatment facility located in the Town of Jewett, Greene County, New York. Serving a population of 725, the plant is situated in the rural Catskill Mountains region, an area known for its forested terrain and headwater streams. The facility operates under the regulatory framework of the US Clean Water Act, with state-level oversight from the New York State Department of Environmental Conservation. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 325.54 megaliters per year, and it currently treats approximately 189.27 megaliters annually, indicating operational headroom. Advanced treatment is typical for facilities discharging to sensitive watersheds, such as those in the Catskill region that supply New York City's drinking water. The treated effluent is discharged to a local waterway within the Schoharie Creek watershed, which flows into the Mohawk River, then the Hudson River, and ultimately the Atlantic Ocean. The Catskill region supports diverse aquatic life and provides critical habitat for native brook trout and other cold-water species. The plant's advanced treatment helps protect downstream water quality in this ecologically sensitive area.

The plant discharges into a tributary of Schoharie Creek, which flows into the Mohawk River, a major tributary of the Hudson River. The Hudson River estuary drains to the Atlantic Ocean. The Catskill watershed is a source of unfiltered drinking water for New York City and supports cold-water fisheries, including brook trout. Advanced treatment at this plant helps minimize nutrient loading and protects downstream aquatic ecosystems.
