New York City Water Tunnel No. 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). 10 NYCRR Subpart 5-1: Boil / Water Disinfection: November-18 About 95% of the city’s water is obtained from the Delaware and Catskill systems and about 3% from the Croton system. 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. 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. Soll vividly recounts the profound environmental implications for both city and countryside. The primary water uses are for public-water supply and industrial-commercial purposes, which together accounted for 202 Mgal/d (million gallons per day) in 1975. While New York has no shortage of water, its infrastructure is quite old. The watershed is located in portions of the Hudson Valley and Catskill Mountains, with areas that are as far as 125 miles north of New York City. Located in Westchester, Putnam, and Dutchess Counties, the Croton system has 12 reservoirs and three controlled lakes. Mains under Broadway and the Bowery delivered the water to hydrants on Pearl, William, Hudson, and a dozen other major streets, in six-, ten-, and 12-inch pipes, delivering water to a height of 60 feet above the highest streets.[5]. [19][20], While all the water goes through the disinfectant process, only 10% of the water is filtered. Most of New York City’s drinking water travels by aqueduct from three upstate reservoir systems, called watersheds. The largest, the New Croton Reservoir, can hold 19 billion gallons of water. The underground filtration plant is under construction in Van Cortlandt Park. Nassau County, New York depends upon ground water for its freshwater supply. [a] The well was immense—16 feet across and 112 feet deep—blasted largely through rock, resulting in a quarry of over 175,000 gallons of water. Four of the members are ex officio members: the Commissioner of Environmental Protection of the City, the Director of Management and Budget of the City, the Commissioner of Finance of the City, and the Commissioner of Environmental Conservation of the State. By the late 1800s, a new aqueduct was under construction to get yet more water from Croton to the City. [14] The UV facility opened on October 8, 2013, and was built at a cost of $1.6 billion. With three major water systems (Croton, Catskill, and Delaware) stretching up to 125 miles (201 km) away from the city, its water supply system is one of the most extensive municipal water systems in the world. [6] In the late 1800s, Additional aqueducts were systematically installed in New York City to fit the demand. What's new in the Division of Water 3. Collect Pond, or "Fresh Water Pond",[4] was a body of fresh water in what is now Chinatown in Lower Manhattan. The watersheds of the three systems cover an area of almost 2,000 square miles, approximately the size of the State of Delaware. The source: More than 90 percent of the city’s water supply comes from the Catskill/Delaware watershed, about 125 miles north of NYC; the … Even though in the late 19th/early 20th century and beyond the Legislature is dominated by rural interests, there’s a recognition that New York City needs an adequate water supply to function. 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. The water towers in New York might look old and yes, they are, but they encompass the past, present, and most likely the future. 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. Chlorine is added to the water to kill bacteria, and fluoride is added to help prevent tooth decay. In April 1831, a new water supply and distribution system opened, for fighting fires. The long and tumultuous story of the development of New York City’s water supply West of the Hudson River began when the New York State Legislature passed Chapter 724 of the Laws of 1905, an act allowing the city to acquire lands and build dams, reservoirs and aqueducts in the Catskills. The DEP has a workforce of over 7,000 employees. [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. [30], In 2018, New York City announced a US$1 billion investment to protect the integrity of its municipal water system and to maintain the purity of its unfiltered water supply. The water-sampling system has been in use since 1997. With almost half of its population living in the urban center of New York City, the state of New York has a unique water supply situation. It is a public-benefit corporation created in 1985 pursuant to the New York City Municipal Water Finance Authority Act. A combination of aqueducts, reservoirs, and tunnels supply fresh water to New York City. A combination of aqueducts, reservoirs, and tunnels supply fresh water to New York City. A comprehensive raised-relief map of the system is on display at the Queens Museum of Art. Construction on the tunnel began in 1970, and its first and second phases are completed. Division of Water BureausNew York's abundant rivers, streams, lakes and coastal waters are used for recreation, fishing, tourism, agriculture and manufacturing. The distance is approximately 125 miles.[9]. They consist of small cast-iron boxes with spigots inside them, raised 4.5 feet (1.4 m) above the ground. This largely reflects how well-protected its watersheds are. The tunnel will eventually be more than 60 miles (97 km) long. Piotr Redlinski for The New York Times This enormous monitoring apparatus is one critical part of New York City’s drinking water supply, ensuring … New York City has three major watersheds: the Croton (located north of the city), Catskill, and Delaware systems, both located west of the Hudson River. A steam engine had the capacity to lift nearly half a million gallons a day. [1] With all the care given, the city's water supply system is exempted from filtration requirements by both the federal and the state government, saving more than "$10 billion to build a massive filtration plant, and at least another $100 million annually on its operation". [18] The compound is the largest ultraviolet germicidal irradiation plant in the world; it contains 56 UV reactors that could treat 2,200,000,000 US gal (8.3×109 L) per day. It includes three bureaus in charge of, respectively, the upstate water supply system, New York City's water and sewer operations, and wastewater treatment: The NYW finances the capital needs of the water and sewer system of the city through the issuance of bonds, commercial paper, and other debt instruments. The latter opened with a ceremony under Central Park, in 2013. As the additions to the original, Schoharie Reservoir and Shandaken Tunnel was put into use 13 years later in 1928. [2] Moreover, the special topography the waterways run on allows 95% of the system's water to be supplied by gravity. While the Bloomberg administration originally budgeted the project at $992 million in 2003, an audit by the city's comptroller placed the actual costs at $2.1 billion in August 2009.[28]. 4 City of New York. Learn about ways to reduces exposure to drinking water contaminants, and maintain and protect household wells and septic systems. The city has sought to restrict development surrounding them. Until the eighteenth century, New York City solely depended on primitive means such as wells and rainwater reservoirs to collect water for daily use. 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. An octagonal iron tank, 43 feet in diameter and 20 feet high was installed atop a 27-foot high stone tower. The first public well was dug in Bowling Green, New York, in 1677, and the first reservoir was built on the east side of New York in 1776 after the population grew up to 22,000.[3]. [23] The 830 by 550 feet (250 by 170 m) plant, which is bigger than Yankee Stadium,[21] is New York City's first water filtration plant. The system also provides about 110 million gallons a day to one million people living in Westchester, Putnam, Orange, and Ulster counties. 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. 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. At 13.5 feet (4.1 m) wide and 85 miles (137 km) long, the Delaware Aqueduct is the world's longest tunnel. New York City is world-renowned for its clean and delicious drinking water. The samples are then tested for microorganisms, toxic chemicals, and other contaminants that could potentially harm users of the water supply system. Forecasting reservoir levels in New York City’s Water Supply System is one of the most important and most difficult tasks we face in the operation of the water supply. (1995), The Encyclopedia of New York City, New Haven: Yale University Press, New York City Department of Environmental Protection § Wastewater treatment, Catskill-Delaware Water Ultraviolet Disinfection Facility, Water supply and sanitation in the United States, "New York's Water Supply May Need Filtering", "A Billion-Dollar Investment in New York's Water", "History of New York City's Drinking Water – DEP", "Welcome to the NYC Water Board Web Site", "New York City's Water Supply System Map", "Catskill-Delaware Water Ultraviolet Disinfection Facility", "NYC Catskill-Delaware UV Facility Opening Ceremony", "TROJAN TECHNOLOGIES WINS NEW YORK CITY DRINKING WATER UV PROJECT", "As a Plant Nears Completion, Croton Water Flows Again to New York City", "Water Hazard? 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. The rest of the watershed is private property that is closely monitored for pollutants; development upon this land is restricted. Find out about the many programs that regulate, protect and help fund New York’s public drinking water systems that supply nearly 95% of New Yorkers with drinking water. It included a well and cistern on 13th Street between Bowery (today 4th Avenue) and Third Avenue, which was then at the northern fringes of the city. [16] Water from both aqueducts is stored first in the large Kensico Reservoir and subsequently in the much smaller Hillview Reservoir closer to the 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. Until the early 21st century, some places in southeastern Queens received their water from local wells of the former Jamaica Water Supply Company.[13]. In 1915, Ashokan Reservoir and Catskill Aqueduct were established. Local and state officials want to study the idea of tapping into New York City's upstate water supply because of concerns about emerging contaminants in Long Island's aquifer. The city had been studying possible sites for such a plant for more than 20 years in both the Bronx and Westchester.[24]. New York City [historically] is the economic engine of the state. For the first two centuries of European settlement in Manhattan, it was the main water supply system for the growing city. [14], In order to comply with federal and state laws regarding the filtration and disinfection of drinking water, the U.S. Environmental Protection Agency (EPA) and the New York State Department of Health called on the city to create a treatment plan to serve the Croton System. The New York City Watershed is the largest unfiltered surface water supply system in the United States. history. [29] A complex five-year project with an estimated $240 million construction cost was initiated in November 2008, to correct some of this leakage. The system normally supplies 10 percent of the City's drinking water, but can supply more when there is a drought in the watersheds farther upstate. Two main tunnels provide New York City with most of the 1.3 billion gallons of water it consumes each day, ninety per cent of which is pumped in from reservoirs upstate by the sheer force of … A group backed by Dow is suing to revoke a new drinking water regulation—and argues Long Island should switch to New York City’s water supply The Hicksville, N.Y, water tower on Dec. 23. The New York City Water Supply System provides one billion gallons of safe drinking water to New York City’s 8.5 million residents every day. 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 New York is covered in rivers and lakes, providing water to the state through various watersheds and surface supplies. To learn about the history of our water supply system, visit History of New York City Drinking Water. 5 Groundwater supply from public sources requires 2,100 kWh/million gallons—about 31% more electricity than surface water supply, mainly due to higher water pumping requirements for groundwater systems. NEW YORK CITY WATER SUPPLY SYSTEM. The New York City (NYC) Water Supply System provides one billion gallons of drinking water to New York City’s 8.5 million residents every day. [7], In 1905, the City's newly-established Board of Water Supply launched the Catskill Aqueduct project, which would play an additional role in supplying the City's ever-growing population of residents and visitors. Dams and other infrastructure help us manage our waters.Though plentiful, the water resources of the state are threatened by chemical contaminants and other pollutants fro… In a message of 50,000 words Mayor McClellan devotes a fairly large share to the subjects of the fire protection and water supply of New York city. One of its largest watershed protection programs is the Land Acquisition Program, under which the New York City Department of Environmental Protection (DEP) has purchased or protected, through conservation easement, over 130,000 acres (53,000 ha) since 1997. It is a spectacular job of research, yet reflects the passion of a native of the city's watershed. 1. [11], The New York City Water Board was established in 1905. New York's water treatment process is simpler than most other American cities. Links to water webpages 2. [14], There are 965 water sampling stations in New York City.

[14] The DEP has purchased or protected over 130,000 acres (53,000 ha) of private land since 1997 through its Land Acquisition Program. The geology of the forests, swamps and farms in the watersheds naturally filter out pollutants, rendering the water pure enough to supply drinking water to over 9 million New Yorkers daily. Located in Westchester, Putnam and Dutche… Completion of all phases is not expected until at least 2021. According to New York City’s website, the Old Croton Aqueduct's capacity was around 90 million gallons per day. 2, completed in 1935. As of 2015[update], it costs the city $140 million to maintain these mains. The Authority is administered by a seven-member Board of Directors. Later, the City was aware of its deteriorated water quality, owing to its rapid population growth (60,000 to 200,000 from 1800 to 1830), which had a considerable danger of causing epidemics. In 2015, the DEP performed 383,000 tests on 31,700 water samples. But in 2013, the Croton Water Filtration Plant, currently under construction in the Bronx, will begin filtering 1.2 million cubic meters or 10% of New York’s water supply each day. 2021 All Rights Reserved, NYC is a trademark and service mark of the City of New York. HISTORY OF THE NYC WATER SUPPLY. Two-fifths of the watershed is owned by the New York City, state, or local governments, or by private conservancies. And by this time, with the population at more than three million people, the City’s newly consolidated Water System – encompassing Manhattan, the Bronx, Brooklyn, Queens, and State Island – was focused on finding new sources of water. The Croton Filtration Plant, which was completed in 2015 at a cost of over $3 billion,[21][22] was built 160 feet (49 m) under Van Cortlandt Park in the Bronx and filters water from the Croton River. New York won the case in May 1931 and construction of the Delaware Aqueduct was initiated in March 1937. The NYC watershed delivers roughly 1.2 billion gallons of unfiltered water each day to 9 million New Yorkers. With three major water systems (Croton, Catskill, and Delaware) stretching up to 125 miles (201 km) away from the city, its water supply system is one of the most extensive municipal water systems in the world. Empire of Water explores the history of New York City’s water system from the late nineteenth century to the early twenty-first century, focusing on the geographical, environmental, and political repercussions of the city’s search for more water. 1 and No. The aqueduct was constructed between 1939 and 1945, and carries approximately half of New York City's water supply of 1.3 billion US gallons (4,900,000 m 3) per day. [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. The New York City Water Supply System consists of three individual water supplies: Learn more about each of the 19 reservoirs that make up New York City’s vast water supply system. In 2008, the New York City water supply system was leaking at a rate of up to 36 million US gallons (140,000 m3) per day. From the Hillview reservoir water flows by gravity to three tunnels under New York City. 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. The Water Supply System is comprised of 19 reservoirs and three controlled lakes and spreads across a 2,000-square-mile watershed. The reservoirs combined have a storage capacity of 550 billion gallons. Water Tunnel 3 is one of the largest public works projects in New York City history, but the water system itself is far larger than one tunnel. Jackson, Kenneth T., ed. [14] The three tunnels are: The distribution system is made up of an extensive grid of water mains stretching approximately 6,800 miles (10,900 km). As New Yorkers reached for the skies in the 1800’s, water towers became an intricate part of the buildings’ framework. The percentage of pumped water does change when the water level in the reservoirs is out of the normal range. [6] The Delaware Aqueduct supports half of the whole City's water usage by supplying more than 500 million gallons of water daily. And if New York City falls apart, the state is not going to succeed. [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.

Members of the Island's Division of Water Mission 4. 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. ; Plan to Put Filtration Plant Under Park Angers the Bronx", "Pressed by U.S., City Hall Agrees To Build a Plant to Filter Water", "Tunnelers Hit Something Big: A Milestone", "Water, Water, Everywhere in Mayoral Race", "Plumber's Job on a Giant's Scale: Fixing New York's Drinking Straw", Information Technology & Telecommunications, Office of Administrative Trials and Hearings, Mayor's Office of Film, Theatre & Broadcasting, New York City School Construction Authority, https://en.wikipedia.org/w/index.php?title=New_York_City_water_supply_system&oldid=1001386854, Short description is different from Wikidata, Articles containing potentially dated statements from 2015, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License, The Bureau of Water Supply manages, operates, and protects New York City's upstate water supply system to ensure the delivery of a sufficient quantity of high quality, The Bureau of Water and Sewer Operations operates and maintains the water supply and sewerage system. 1, completed in 1917. The system also provides about 110 million gallons a day to one million people living in Westchester, Putnam, Orange, and Ulster counties. "New York City has been building water supply infrastructure almost continuously for 170 years,” said Kevin Bone, a professor at Cooper Union, and co-author of “Water-Works: The Architecture and Engineering of the New York City Water Supply,” the definitive history of New York City’s infrastructure. In 2015, the buoys took 1.9 million measurements of the water in the reservoirs. [14], The water is monitored by robotic buoys that measure temperature as well as pH, nutrient, and microbial levels in the reservoirs. The construction of Water tunnel No. About 40% of New York City’s water supply flows through the Catskill Aqueduct. [32], New York City Department of Environmental Protection, New York City Municipal Water Finance Authority, Union Square, eventually built one block to the north, had not yet been begun, as shown in. [12], New York City's water system consists of aqueducts, distribution pipes, reservoirs, and water tunnels that channel drinking water to residents and visitors. [14], The water from the reservoirs flows down to the Catskill-Delaware Water Ultraviolet Disinfection Facility, located in Westchester. Even though the request was approved, the Delaware Aqueduct project was delayed due to a Supreme Court case filed by the State of New Jersey to prevent the State of New York from using the Delaware River as a water source. Every day this region in upstate New York’s Catskill Mountains provides more than a billion gallons of clean drinking water to the more than 9 million people residing in New York City and upstate counties. The remaining three members are public appointments: two by the Mayor, and one by the Governor. Water rises again to the surface under natural pressure, through a number of shafts.
