New York American Water Releases 2020 Fall Flushing Schedule

MERRICK, N.Y. (September 24, 2020) - New York American Water will begin flushing water mains throughout its Long Island service territory on Tuesday, September 29, as part of its routine maintenance program to provide quality water service to customers. The purpose of this important task is to clean out the buildup of mineral deposits and sediment, which may have accumulated over time within the pipes. The process of flushing water mains involves opening fire hydrants in specific locations to increase water flow in an area.

 “Water main flushing is a best practice used by many water providers to remove sediment and mineral buildup that accumulates in aging water mains over time,” stated New York American Water Vice President of Operations Jim Runzer. “Our annual flushing program begins Tuesday, September 29, and we encourage customers to check the schedule to see when their community is scheduled for flushing. We also encourage customers to follow us on Facebook, where we will be posting daily flushing locations.”

During flushing in their neighborhood, customers may detect a decrease in water pressure or encounter discolored water. This is a normal part of the flushing process. If a customer experiences discolored water while flushing is occurring, they are asked to run their cold water until the discoloration clears. 

New York American Water also shares the following tips to help customers better prepare for flushing in their neighborhood:

  • Make note on your calendar of your community’s scheduled time to be prepared for the flushing process.
  • Draw water needed for cooking ahead of time and set aside a large bottle of water in the refrigerator for drinking.
  • Check for discolored water prior to using the washing machine or dishwasher. Wait until the water runs clear before using the washing machine or running the dishwasher.
  • If laundry becomes stained, do not put your laundry in the dryer. Rewash clothes promptly using a heavy duty detergent and add a rust remover. Most rust removers can also be used on stained fixtures.
  • If water pressure or water volume seems low after flushing has been completed, inspect the faucet screens for trapped particles.
