New York American Water to Flush Water Mains and Hydrants: Flushing will Begin October 15 and Continue into November

MERRICK, N.Y. (September 24, 2018)—New York American Water will be flushing portions of its water distribution system this fall as part of its commitment to delivering high-quality water service to its customers. This essential part of the company’s maintenance program is performed to clear harmless mineral deposits and sediment that may have built up over time inside the pipes. The process includes flushing water through fire hydrants, which also doubles as an opportunity to make sure they are operational and have adequate flow to fight fires.

“Flushing water mains are a standard part of New York American Water’s maintenance protocols, but the process plays an important role in maintaining the overall health of the distribution system,” said Moses Thompson, New York American Water’s Vice President of Operations. “We ask residents to be mindful of the scheduled flushing days in their neighborhood and to contact us with any questions or concerns they may have during this process.”   

 New York American Water will be flushing portions of its water mains throughout its service areas according to the following schedule:



October 15 - October 24

North Woodmere, Woodmere, Hewlett, Valley Stream

October 25 - November 2

Malverne, Cedarhurst, East Rockaway

November 5 - November 15

Inwood, Meadowmere Park, Lawrence, Atlantic Beach, Lynbrook, West Hempstead, Lakeview


When water main flushing is occurring, customers may notice a drop in water pressure or experience discolored water. This is a normal part of the process and residents should NOT be alarmed if it happens. New York American Water advises its customers who experience discolored water to let their cold water lines run until they clear.

  New York American Water offers its customers the following tips:

  • Mark your calendar to be prepared when the company begins flushing the water mains in your neighborhood.
  • Draw water for cooking ahead of time, and store a large bottle of water in the refrigerator for drinking.
  • Check for discolored water before using the washing machine or dishwasher. Wait until the water runs clear at the tap before doing laundry or running the dishwasher.
  • If laundry becomes stained, do not put your laundry in the dryer. Rewash clothes immediately using a heavy duty detergent and add a rust remover. Most rust removers can be used on stained fixtures.
  • In some cases, slight discoloration may linger for a few hours. This discoloration only affects the appearance of the water and does not affect the water quality.
  • If water pressure or water volume seems low after flushing has been complete, check faucet screens for trapped particles.

New York American Water also reminds residents to occasionally flush their own hot water heater. When the temperature of water reaches above 120 degrees, it can lead to greater formation of sediment and therefore can cause water discoloration. Flushing removes that sediment and should be performed at minimum once a month. For instructions on how to properly flush your water heater, please view a step-by-step video here:
