Kensico-Eastview Connection Tunnel

The New York City Department of Environmental Protection (DEP) is carrying out a $1.2 billion tunneling project that will improve operational flexibility between facilities that are vital to the drinking water supply for more than nine (9) million people in the City and Westchester County.

A Public Works project, the Kensico-Eastview Connection (KEC) will be New York City’s largest water-supply tunneling effort in Westchester County since the 1940s, and its construction will create hundreds of jobs for local laborers. Construction on the first elements of the project is expected to start in approximately five years.

The centerpiece of the project is a two (2)-mile long tunnel between Kensico Reservoir and the Catskill-Delaware Ultraviolet Light Disinfection Facility in Eastview.

IEI is assisting the DEP in the preliminary and final design of the project. IEI is assisting NYCDEP with the site design and layout of the 75-acre Kensico Site adjacent to the Kensico Reservoir. The design includes civil site, roadway design, drainage design, stormwater management, and (Stormwater Pollution Prevention Plan) SWPPP. The stormwater management design includes the implementation of multiple bio-retention basins, swales and a detention pond within the site to improve water quality and reduce stormwater runoff.
