Catskill/Delaware Water Supply System Reservoirs. The remaining three members are public appointments: two by the Mayor, and one by the Governor. By the late 1800s, a new aqueduct was under construction to get yet more water from Croton to the City. [22] It was built after a 1998 lawsuit by the presidential administration of Bill Clinton, which Mayor Rudy Giuliani settled under the condition that the city of New York would build the plant by 2006. A combination of aqueducts, reservoirs, and tunnels supply fresh water to New York City. Diane Galusha's book, "Liquid Assets: A History of New York's Water System Expanded Edition" tells the epic tale of the city's water supply from colonial days to the present. A comprehensive raised-relief map of the system is on display at the Queens Museum of Art. Until the eighteenth century, New York City solely depended on primitive means such as wells and rainwater reservoirs to collect water for daily use. [8] The Catskill System has an operational capacity of approximately 850 million gallons per day. The percentage of pumped water does change when the water level in the reservoirs is out of the normal range. It sets water and sewer rates for New York City sufficient to pay the costs of operating and financing the system, and collects user payments from customers for services provided by the water and wastewater utility systems of the City of New York. 1667 Manhattan's first public drinking water well at southern edge of the island; originally Manhattan had up to 300 springs (well on Columbia Campus); the Manhattan Company, now Chase Manhattan, originally managed the city's water supply; 1842 Croton water arrived in the city, superseded the use of springs in Manhattan [14], There are 965 water sampling stations in New York City. In 1915, Ashokan Reservoir and Catskill Aqueduct were established. [14], The water from the reservoirs flows down to the Catskill-Delaware Water Ultraviolet Disinfection Facility, located in Westchester. Responsibility for the city water supply is shared among three institutions: the New York City Department of Environmental Protection ("DEP"), which operates and maintains the system and is responsible for investment planning; the New York City Municipal Water Finance Authority ("NYW"), which raises debt financing in the market to underwrite the system's costs; and the Water Board, which sets rates and collects user payments.

The watersheds of the three systems cover an area of almost 2,000 square miles, approximately the size of the State of Delaware. [17][14] The facility was built because chlorinated water might have unintended side effects when mixed with certain organic compounds, and ultraviolet was seen as the least risky way to clean the water of any microorganisms. The Authority is administered by a seven-member Board of Directors. The Old Croton Aqueduct was established in 1842, and apart from a few inspections during the Civil War era the system has been running unceasingly ever since. In 1842, the City's first aqueduct, the Croton Aqueduct, was built from the Croton River along a section within Westchester County, down to Manhattan. The water flows to New York City through aqueducts, and 97 percent reaches homes and businesses through gravity alone; only 3 percent must be pumped to its final destination. 2009 State of New York Public Water Supply Annual Compliance Report: July-10: Annual Report for Public Drinking Water Systems with Violations: 10 NYCRR Subpart 5-1: Flood Recovery: July-06: Provides links to Restoring Water Wells, Sampling Private Wells, and Well Sampling Laboratories. Three separate sub-systems, each consisting of aqueducts and reservoirs, bring water from Upstate New York to New York City: The latter two aqueducts provide 90% of New York City's drinking water, and the watershed for these aqueducts extends a combined 1,000,000 acres (400,000 ha). The system also provides about 110 million gallons a day to one million people living in Westchester, Putnam, Orange, and Ulster counties. 3 is intended to provide the city with a critical third connection to its Upstate New York water supply system so that the city can, for the first time, close tunnels No. Reservoir levels are primarily determined by the balance between streamflow into the reservoirs, diversions (withdrawals) for water supply, and releases to maintain appropriate flows in the rivers below the dams. [14] The DEP has purchased or protected over 130,000 acres (53,000 ha) of private land since 1997 through its Land Acquisition Program. [31] A significant portion of the investment will be used to prevent the turbidity that might be caused by climate change, including relocating the residents and cleaning up decaying plantations near the watersheds, and conducting flood-preventing research for infrastructures near the watersheds.

[6] In the late 1800s, Additional aqueducts were systematically installed in New York City to fit the demand. Constructed between 1939 and 1945, the Delaware Aqueduct carries approximately half of the New York City water supply of 1.3 billion gallons per day. To meet growing needs, the New Croton Aqueduct project was launched in 1885 and established in 1890, running with a capacity of 300 million gallons per day.

With an investment approaching $3 billion from 1993 to 2019, NYC Department of Environmental Protection (DEP) is interested in understanding the economic impacts of source water protection. New York is covered in rivers and lakes, providing water to the state through various watersheds and surface supplies. Located in Westchester, Putnam and Dutche… [12], New York City's water system consists of aqueducts, distribution pipes, reservoirs, and water tunnels that channel drinking water to residents and visitors. [2] Moreover, the special topography the waterways run on allows 95% of the system's water to be supplied by gravity. HISTORY OF THE NYC WATER SUPPLY.
