Each spring, Concord General Services' Highway and Utilities Division flushes City-owned hydrants as part of required routine maintenance to remove any sediment from water distribution pipes. This process maintains water quality, water clarity, and also checks for water pressure. Water customers may experience low water pressure and discolored water in their area during hydrant flushing. Residents should avoid doing laundry during their scheduled flushing time. If discoloration occurs, please run your tap water on cold until the water runs clear.
Hydrant flushing has started as of Monday, April 15, 2019. Flushing will continue for several weeks in different areas of the city. Concord water customers should view the tentative flushing schedules below to determine when flushing is scheduled to occur in their area. Notices will be sent out weekly to confirm flushing schedules in case of any scheduling changes. Customers should remember to avoid doing laundry during their flushing time and to run their tap on cold to flush the lines if discoloration occurs.
