Hydrants are flushed to help remove sediment, iron, and other minerals that settle in some of our water mains. However, the main reason we flush the hydrants is for all of our protection. We want to make sure that the fire hydrants in our distribution system all work properly.
Some residents have experienced problems with water discoloration during hydrant flushing. If you see the crew working in your area, run your cold water tap for about 10 minutes and the color should disappear. Do not be alarmed if the water is yellow/slightly red because it will not harm you. Thediscoloration is caused by the turbulence of the water while flushing the hydrants. Usually after about 1/2 hour to an hour, the discoloration will subside as the water main has had a chance tosettle down.
