The City of Danbury Water Department will be flushing fire hydrants beginning today. The entire process will be completed in about nine weeks. Fire officials say annual flushing of the hydrants is necessary to provide better quality water and fire protection. Water customers may experience fluctuations in pressure and/or discoloration of their water during flushing. If that happens, the cold water tap should be left on until it runs clears. During periods of discoloration, postpone washing clothes and limit your use of hot water until the cold water clears.The City's website includes an updated list of streets to be flushed in a given week.
