The Kensico Reservoir, located in Westchester County, collects water from eight upstate reservoirs and is the last major stop for city water before it flows to our taps. The NYC Department of Environmental Protection (DEP) draws nearly 1 billion gallons of water from the Kensico Reservoir each day to serve 9 million New Yorkers.

DEP is undertaking a nearly $2-billion project at the 110-year-old reservoir to ensure long-term resilience of the water supply system, including building a new 2-mile-long tunnel hundreds of feet below ground to convey drinking water.

This program will take visitors to the top of the Kensico Dam with John Milgrim, Director of External Affairs, New York City Water Supply. Standing atop the structure holding back 30-billion gallons of water, learn about the history of New York City’s watershed, the construction of the reservoir and aqueduct systems, and how DEP protects New York City’s famous drinking water for generations to come.

OHNY to provide a shuttle between Valhalla Station and the tour starting point. Shuttle details to be announced. 

The tour will take place primarily on the top of the dam, which is a flat, paved walkway. The tour involves standing outdoors for up to an hour with minimal walking. Dress for the weather and wear sunscreen. 

Very limited street parking is available near the meeting location. OHNY will provide a shuttle between Valhalla Station and the tour starting point. Walking from the station to the tour starting point on foot is not recommended. The elevation is equivalent to climbing a 20 story building.
