context: The Board of Water Supply requested to use the Delaware River as an additional water source for New York City in 1927 to the Board of Estimate and Apportionment. Even though their request was improved, 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. New York won the case in May 1931, and in March of 1937 the construction of the Delaware Aqueduct was initiated. The Aqueduct was completed in 1944, and from 1950 to 1964 Rondout, Neversink, Pepacton, and Cannonsville Reservoir were established successively to complete the Delaware System. With more than 500 million gallons of water operating to the City per day, Delaware Aqueduct supports half of the whole City's water usage.

context: While all the water goes through the disinfectant process, only 10% of the water is filtered. The Croton Filtration Plant, which was completed in 2015 at a cost of over $3 billion, was built under Van Cortlandt Park in the Bronx and filters water from the Croton River. The plant, which is bigger than Yankee Stadium, is New York City's first water filtration plant. 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. The city had been studying possible sites for such a plant for more than 20 years in both the Bronx and Westchester.
