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. The discoloration 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 to settle down.
