Delaware Aqueduct

The Delaware Aqueduct is the newest of the New York City aqueducts. It takes water from the Rondout Reservoir through the Chelsea Pump Station, the West Branch Reservoir, and the Kensico Reservoir, ending at the Hillview Reservoir in Yonkers, New York.
The aqueduct was constructed between 1939 and 1945, and carries approximately half of the New York City water supply of per day. The Delaware Aqueduct leaks up to per day. A $1 billion project to repair the leaking was scheduled to begin in January 2013.
At long and wide, the Delaware Aqueduct is the world's longest tunnel.
==Leaks==
Since the late 1970s, the New York City Department of Environmental Protection (NYCDEP) has been monitoring two leaks in the Delaware Aqueduct that collectively release between of water per day. These leaks have caused many problems with flooding and drinking water contamination, particularly for residents of Wawarsing, New York, and in the town of Newburgh, 35 miles southeast, residents thought that a stream bubbling out of a wetlands was a natural artesian well. In reality, the water was coming out of a 36-square-foot tunnel carved out by the force of water blasting from a crack in the aqueduct buried 650 feet underground. Combined with the leak in Wawarsing, the NYCDEP admitted in the early 1990s that the aqueduct was leaking at a rate of up to 35 million gallons a day, enough water to supply nearly half a million people a day.
