January 30, 2018 - The Water Authority is taking a seasonal well out of service that may result in localized discolored water in the general area of North New Hyde Park outlined on the map below.

The Water Authority will be monitoring the area and proactively flushing water mains to remove the discoloration.

The water continues to be safe and poses no health risks. Discolored water usually results when sediment on the bottom of water mains is disturbed by a reversal in the direction of water flow or a sudden change in pressure. When the flow equalizes, the water will clear up as the sediment settles out of the water.

If you experience any discoloration, to let your cold water faucet run for at least 15 minutes until the water runs clear.
Customers should refrain from using hot water until their cold water clears and avoid doing any laundry until the water clears.
If the problem persists, please contact the Water Authority at (516) 327-4100.
