The UV facility treats water delivered by two of the city's aqueduct systems, the Catskill Aqueduct and the Delaware Aqueduct, via the Kensico Reservoir. [3] (The city's third supply system, the New Croton Aqueduct, has a separate treatment plant. [4]) The plant has 56 energy-efficient UV reactors, and cost the city $1.6 billion.
The New York City Water Board was established in 1905. 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 city's wastewater is collected through an extensive grid of sewer pipes of various sizes and stretching over 7,400 miles (11,900 km). The Bureau of Wastewater Treatment (BWT) operates 14 water pollution control plants treating an average of 1.3 billion US gallons (4,900,000 m 3) of wastewater a day; 96 wastewater pump stations: 8 dewatering facilities; and 490 sewer regulators.
Removing contaminated water, both in the plant itself and run-off water that spread into the sea and nearby areas, became a huge challenge for the Japanese government and plant workers. During the containment period following the accident, thousands of cubic meters of slightly contaminated water were released in the sea to free up storage for ...
The Croton Water Filtration Plant, is a drinking water treatment facility in New York City which began operation in 2015. The plant construction cost was over $3 billion, [ 6 ] [ 3 ] The facility was built 160 feet (49 m) under Van Cortlandt Park 's Mosholu Golf Course in the Bronx .
From this process, some strategies have been designed based on sequences of ponds with a slow flow of water to clean polluted water with radionuclides. The results of these facilities, for flows of 1000 liters of effluent are about 95% retention of radiation in the first pond (by plants and sludge), and over 99% in three-base systems. [33]
Capacity in the section of the aqueduct south of Kensico Reservoir to the Hillview Reservoir in Yonkers, New York is 880 million US gallons (3,300,000 m 3) per day. [7] The aqueduct normally operates well below capacity with daily averages around 350–400 million US gallons (1,500,000 m 3 ) of water per day.
The plant was originally constructed in 1967. [3] The plant's unusual public amenities, which include a visitors' center with a manmade waterfall, a nature walk along the Newtown Creek, and the dramatic aesthetic elements, all stem from a long-term upgrade project that was begun by the city in 1998 and is scheduled for completion in 2014.
