Knox residents may notice discolored tap water this week due to scheduled fire hydrant flushing. Water department crews will begin routine maintenance and testing throughout the city today. The work is expected to wrap up on Wednesday. Discolored water is still safe for all uses and does not need to be boiled prior to drinking or cooking. The fastest way to flush your service line is to turn on your cold water tap in the bathtub and let the faucet run until the water clears up.
