NJAW Hydrant Flushing Program

Hydrant Flushing Update as of 4/7/22

NJ American Water has issued the following  notification. Our crews will begin routine flushing of the water distribution system in your area 4/11/2022 through 5/6/2022 to ensure that you continue to receive high-quality water service. Flushing also allows us to test and maintain fire hydrants. When crews are working in your area, you may notice reduced pressure or discolored water. If your water is discolored, run the cold water taps only, at the lowest level of the house for about 3 to 5 minutes until the water runs clear. If discolored water occurs, please also refrain from doing laundry during that time. In keeping with American Water’s focus on safety for both customers and employees, please do not approach our crews while they work. For more information and to see a map of the affected area please go to NewJerseyamwater.com or call 1.800.272.1325. We apologize for any inconvenience and thank you for your patience and understanding while we undertake this necessary maintenance of the water system.  More information regarding this alert.


Flushing our system helps to clean out any build-up of mineral deposits and sediment inside the pipes. These harmless deposits can occur when there is a reduced water demand. We also flush our hydrants to make sure they are operational and to check fire flows in our system, which is critical for firefighting.


Flushing involves simultaneously opening fire hydrants in a specific area to create increased water flows. When our crews are on your street or nearby, this process usually takes about one hour.


When crews are in your area, you may notice a drop in water pressure or discolored water. Discolored water may occur because the sediment in the water mains gets stirred up when the fire hydrants are used and when the flow of water in the mains is changed. This is normal and temporary. If this happens, simply let your cold water run until it is clear.


  • Sign up for our customer notification system at https://www.amwater.com/njaw/ to receive a call, text, or email to let you know when we’ll be flushing in your neighborhood.
  • Draw water for cooking ahead of time.
  • Store a large bottle of water in the refrigerator for drinking.
  • Check for discolored water before using the washing machine or dishwasher.


  • Avoid running your tap water and using the washing machine or dishwasher while crews are flushing in your area.
  • If discolored water occurs, simply run the cold water for a few minutes until it is clear. This will allow the sediment to work its way through your pipes.
  • 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. NOTE: If your laundry becomes stained, DO NOT PUT YOUR LAUNDRY IN THE DRYER. Rewash clothes immediately using detergent and add a rust remover. Most rust removers can also be used on stained fixtures.

In some cases, slight discoloration might linger for a few hours. This discoloration only affects the appearance of the water and does not affect water quality. No health hazards are associated with discolored water from hydrant flushing. If water pressure or water volume seems low after flushing has been completed, check your faucet screens for trapped particles.
