Fire hydrants are opened to conduct regular water system flushing that removes any mineral build-up and sediment from the pipes and also to ensure that water circulates adequately throughout the system.

Fire hydrants may also be opened to conduct fire-flow capability tests. This process assures that fire hydrants are functioning properly in case of an emergency.

Although it may appear to be a waste of water, this process is part of a routine maintenance program necessary to maintain the integrity of the water system and to continue to deliver the highest quality water possible to our customers.

You May See These Occasional Results from Hydrant Flushing:
As a result of the flushing procedure, residents in the immediate vicinity of the area of hydrant flushing may experience temporary discoloration of their water. This discoloration consists primarily of harmless silt and precipitates and does not affect the safety of the water. If you notice that your water is discolored after crews have been flushing in your neighborhood, run all water faucets for a minute or two, in order to clear the pipes in your home.
