Commissioner Rohit T Aggarwala introduces himself and provides an overview of New York City's water supply system. He describes the network of reservoirs and the sources of the city's water.
- The water supply comes from 19 collecting reservoirs upstate
- 10% of annual consumption typically comes from the Croton network, which is filtered
- 90% usually comes from the Delaware and Catskill watersheds, which are covered by the Filtration Avoidance Determination (FAD)

New York City's water supply comes from a network of 19 collecting reservoirs upstate, ranging from Kensho in Westchester to Skohari and Canonsville each more than 100 miles away from the city.

2 other reservoirs Hillview and Yonkers and Jerome Park in the Bronx are only holding reservoirs and do not collect runoff.

Typically, 10% of our annual water consumption comes from the Croton network of reservoirs in Westchester Putnam And Duchess Counties, which are the oldest reservoirs and are the successors of the original Croton system of 1842.

Croton water is all filtered at our Croton filtration plant in the Bronx, which opened in 2015.
0:28:50
And as you know, due to the currently ongoing repair of the Delaware aqueduct, roughly 30% of our water right now is coming from the Croton system.
0:28:58
In normal periods, 90% of our consumption comes from the Delaware and Cascale watersheds, which are entirely west of the Hudson River.
