2020 Hydrant Flushing Schedule

An Essential part of our system maintenance program

*Please note that this list is partial, and we will continue to update as flushing dates are scheduled. Check website weekly to find out when we're flushing in your area.

Each Spring, we flush the pipes in our water distribution system. Flushing is a critical component to maintaining a healthy water system. This is an essential part of our system maintenance program, and is unrelated to the current COVID-19 pandemic.
Our drinking water treatment barriers provide protection that includes filtration and disinfection of our water supplies. These treatments are effective in removing and/or inactivating viruses. Our water meets all current federal and state drinking water requirements.


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 water mains get stirred up when the fire hydrants are used and when the flow of water in mains is changed. This is normal and temporary. If this happens, it is not harmful. Simply let your cold water run until it is clear.


  • Sign up for our CodeRED customer notification system at www.myaccount.amwater.com 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 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.


We will use our phone/text/email customer notification system to notify you before we begin flushing your neighborhood. You must opt-in to these types of non-emergency alerts.
