Why are hydrants flushed?

Hydrants are flushed to circulate fresh water. Most municipal water systems perform annual hydrant flushing to ensure delivery of the best water quality.  

Tap water may be discolored in your immediate area during flushing. Run water for a few minutes and make sure it is clear before using. Be sure to check the water before washing clothes, as sediment in the water may stain clothing.
