YORKTOWN, N.Y. - Yorktown residents are being asked to conserve as much water as possible while its supply is switched to the Amawalk Reservoir, the Northern Westchester Joint Water Works announced.

This is being done as a result of the New York City Department of Environmental Protection's $158 million rehabilitation project to the Catskill Aqueduct, which supplies water to Yorktown. To perform this work, the DEP is shutting down the Catskill Aqueduct annually for 10 weeks during the years 2018, 2019 and 2020.

The Northern Westchester Joint Water Works said it has "been actively preparing for this shutdown through ongoing capital projects aimed at ensuring a reliable redundant water supply is available.

"Although adequate capacity will be available to meet our water demand, we will not have a backup supply in the event of an emergency," Northern Westchester Joint Water Works continued. "For this reason, the NWJWW along with our partnering members, request the public conserve water as much as possible."
