The NYC water supply system provides 1.4 billion gallons of drinking water to almost 9 million New Yorkers every day.
The NYC watershed is comprised of 19 reservoirs in an area of almost 2,000 square miles.
The NYC water supply is divided into the Croton System and the Catskill/Delaware system. 90% of NYCÅs water supply is moved to the Kensico Reservoir before being delivered to customers in the City and Westchester.
The Kensico Reservoir serves as the terminal reservoir for six other in the Croton and Catskill/Delaware system.
The Kensico Reservoir holds 30.6 billion gallons of water at full capacity.
The water enters the city through tunnels. The newest and largest is Tunnel No. 3, and when complete, will be the longest tunnel in the United States.
