The taste of tap water in the city may change due to the adjustment.
New York City is set to shut down a key aqueduct providing nearly half the city’s water supply this winter.
The shutdown is part of a $2 billion project aimed at addressing significant leaks under the Hudson River.
The Delaware Aqueduct, located in upstate New York, has been scheduled for this temporary shutdown for years.
City officials have been gradually increasing capacity from other parts of the city’s 19-reservoir water system to prepare.
Water will continue to flow through New York City’s faucets during the shutdown, but its taste might change as the city relies more heavily on alternate water sources.
“The water will always be there”, said Paul Rush, deputy commissioner for the city’s Department of Environmental Protection. “We’re going to be changing the mix of water that consumers get.”
The Delaware Aqueduct is the world’s longest tunnel, extending 85 miles from four reservoirs in the Catskill region to other reservoirs in New York City’s northern suburbs.
