Frontier-Kemper parent company Tutor Perini said in a statement last week that the scope of work calls for the construction of a new deep rock tunnel between the Kensico Reservoir and the Catskill/Delaware Ultraviolet (CDUV) Light Disinfection Facility.

The project aims to enhance the “operational resiliency and redundancy” of the water supply system that supplies New York City.  

Work is expected to begin in the coming months, and a substantial portion of the project will be completed by 2030.

Frontier-Kemper Constructors specializes in the engineering and construction of deep shafts and tunnels. 

The 30.6 billion gallon Kensico Reservoir is about 3 miles north of White Plains and 15 miles north of New York City.    

The reservoir was formed by damming the Bronx River and put into service in 1915. Its primary role is to receive water from Catskill and Delaware Aqueducts and make it available for New York City’s consumption.
