The East Delaware Tunnel is a 25-mile (40 km) aqueduct in the Catskill Mountains of New York State. It was constructed within a six-year period between 1949 and 1955 to transport drinking water from the Pepacton Reservoir to the Rondout Reservoir, both of which supply New York City with drinking water. The tunnel begins near the former site of Pepacton, New York, and ends near the former site of Eureka, New York, passing through Delaware County, Sullivan County and Ulster County. The tunnel has a maximum transmission capacity of 500,000,000 US gallons (1.9 Gl) and was constructed at a width of 11 feet (3.4 m).
