On the  12.07.2018 the New York City Department of Environmental Protection (DEP) announced plans for a EUR1.03 bn (USD1.2 bn) tunnelling project that will improve operational flexibility between facilities that are vital to the drinking water supply for more than 9 million people in the City and Westchester County. The public works project will be New York City’s largest water-supply tunnelling effort in Westchester County since the 1940s. Construction on the first elements of the project is expected to start in approximately five years.

The centrepiece of the project, known as the Kensico-Eastview Connection (KEC), will be a 3 km (2 mile) long tunnel between Kensico Reservoir and the Catskill-Delaware Ultraviolet Light Disinfection Facility in Eastview. The tunnel will stretch from an intake chamber on the western side of Kensico Reservoir to a connection point at the ultraviolet disinfection facility.

DEP expects the finished tunnel to measure approximately 8.23  m (27 feet) in diameter and run 122-152 m (400-500 feet) below ground. The tunnel will be large enough to carry a maximum of  9.84 bn litres (2.6 billion gallons) of water each day. Work on the tunnel itself is expected to begin around 2025. DEP expects to finish the project around 2035. Visit http://www.nyc.gov/html/dep/html/press_releases/18-070pr.shtml#.W1GdmdUzYdU.29/18.
