Scientists from the city measure water from 50 stations every day. In April 1831, a new water supply and distribution system opened, for fighting fires. The New York City Watershed is the largest unfiltered surface water supply system in the United States. Chlorine is added to the water to kill bacteria, and fluoride is added to help prevent tooth decay. New York City [historically] is the economic engine of the state. 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 purchased or protected over 130,000 acres (53,000 ha) of private land since 1997 through its Land Acquisition Program. Soll vividly recounts the profound environmental implications for both city and countryside. 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.  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). About 40% of New York City’s water supply flows through the Catskill Aqueduct. The Authority is administered by a seven-member Board of Directors.

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.  In the late 1800s, Additional aqueducts were systematically installed in New York City to fit the demand. The water system has a storage capacity of 550 billion US gallons (2.1×109 m3) and provides over 1.2 billion US gallons (4,500,000 m3) per day of drinking water to more than eight million city residents, and another one million users in four upstate counties bordering on the system. Completion of all phases is not expected until at least 2021. 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.. The reservoirs combined have a storage capacity of 550 billion gallons. A combination of aqueducts, reservoirs, and tunnels supply fresh water to New York City. Until the eighteenth century, New York City solely depended on primitive means such as wells and rainwater reservoirs to collect water for daily use. For information about how the water from our supply systems is distributed for consumption in New York City, visit Current Water Distribution. The watersheds of the three systems cover an area of almost 2,000 square miles, approximately the size of the State of Delaware. The tunnel will eventually be more than 60 miles (97 km) long. To be noted, Catskill aqueduct is the furthest away from the City in the water system.  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". The percentage of pumped water does change when the water level in the reservoirs is out of the normal range. New York's water treatment process is simpler than most other American cities. , There are 965 water sampling stations in New York City. 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.

While New York has no shortage of water, its infrastructure is quite old. 4 A computer system then analyzes the measurements and makes predictions for the water quality. City of New York. 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… A comprehensive raised-relief map of the system is on display at the Queens Museum of Art.  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. Until the early 21st century, some places in southeastern Queens received their water from local wells of the former Jamaica Water Supply Company..  Water from both aqueducts is stored first in the large Kensico Reservoir and subsequently in the much smaller Hillview Reservoir closer to the city. The underground filtration plant is under construction in Van Cortlandt Park. Electricity use accounts for around 80% of municipal water processing and distribution costs. In 2015, the buoys took 1.9 million measurements of the water in the reservoirs. 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 samples are then tested for microorganisms, toxic chemicals, and other contaminants that could potentially harm users of the water supply system.  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. 2, completed in 1935. Water rises again to the surface under natural pressure, through a number of shafts. The system also provides about 110 million gallons a day to one million people living in Westchester, Putnam, Orange, and Ulster counties.

Located in Westchester, Putnam, and Dutchess Counties, the Croton system has 12 reservoirs and three controlled lakes. To learn about the history of our water supply system, visit History of New York City Drinking Water. 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. Visit Reservoir & Release Levels to learn more.  Moreover, the special topography the waterways run on allows 95% of the system's water to be supplied by gravity. Collect Pond, or "Fresh Water Pond", was a body of fresh water in what is now Chinatown in Lower Manhattan. , 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.
