Wawarsing T Kerhonkson STP | Advanced Wastewater Treatment in Town of Wawarsing, New York

Wawarsing T Kerhonkson STP is a municipal wastewater treatment facility located in the Town of Wawarsing, Ulster County, New York. The plant serves a small population of 550 residents and operates under the regulatory framework of the United States Clean Water Act, administered by the New York State Department of Environmental Conservation. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 283.91 megaliters per year and an actual discharge volume of 208.20 megaliters per year, the facility operates below its capacity. Advanced treatment is typical for plants discharging to sensitive water bodies or requiring high effluent quality. The treated effluent is discharged into a local water body that eventually drains into the Hudson River watershed. The Hudson River estuary supports diverse aquatic life and is an important ecological corridor. The plant's advanced treatment helps protect downstream water quality in this regionally significant basin.

The plant discharges into a tributary of the Hudson River, which flows southward to New York Harbor and the Atlantic Ocean. The Hudson River estuary is a critical habitat for migratory fish such as striped bass and American shad, and supports diverse aquatic ecosystems. Advanced treatment at this plant helps reduce nutrient loading and protects water quality in this ecologically sensitive watershed.
