There are 965 water sampling stations in New York City. The water-sampling system has been in use since 1997. They consist of small cast-iron boxes with spigots inside them, raised 4.5 feet (1.4 m) above the ground. [28] Scientists from the city measure water from 50 stations every day.
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 Croton Distributing Reservoir, also known as the Murray Hill Reservoir, was an above-ground reservoir at 42nd Street and Fifth Avenue in the New York City borough of Manhattan. Covering 4 acres (16,000 m 2 ) and holding 20 million US gallons (76,000 m 3 ), [ 1 ] it supplied the city with drinking water during the 19th century.
