摘要

The Environmental Department (DEP) of New York City said it will begin building a 5-km (3-mile) tunnel in the Hudson Valley to fix leaks in one of the city's aqueducts. The cost of the fix is roughly $1 billion, the Examiner.com reported. A portion of the aqueduct leaks between 56.7 and 132 ML/d (15 and 35 million gal/day) of water of the more than 1.9 GL (500 million gallons) that passes through it daily, said DEP. The department has been monitoring the leaks since the 1990s. Years of study, it says, show that cracking and leaks occur in a section of the tunnel that passes through limestone.
