About
The Catskill-Delaware Water Ultraviolet Disinfection Facility is a 270,000-square-foot (25,000 m2) ultraviolet (UV) water disinfection plant built in Westchester County, New York, to disinfect water for the New York City water supply system. The compound is the largest ultraviolet germicidal irradiation plant in the world.
The UV facility treats water delivered by two of the city's aqueduct systems, the Catskill Aqueduct and the Delaware Aqueduct, via the Kensico Reservoir. (The city's third supply system, the New Croton Aqueduct, has a separate treatment plant.)
