Enhancing New York City’s Water Infrastructure through the Kensico-Eastview Connection Project

The Kensico-Eastview Connection (KEC) project, an essential component of New York City’s ongoing efforts to strengthen and modernize its water supply infrastructure. The KEC Project is designed to improve operational resiliency and redundancy by constructing a new tunnel that will convey water between the Kensico Reservoir and the Catskill/Delaware Ultraviolet Light Disinfection (CDUV) Facility.

The KEC project includes the construction of a new 2-mile-long, deep rock tunnel to transport water from the Kensico Reservoir to the CDUV Facility, enhancing the city’s ability to manage and treat water. This tunnel, along with new shafts, a screen chamber, and other infrastructure improvements, will ensure that New York City’s water supply remains safe and reliable for millions of residents.
