      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)
