Hydrant Flushing Began April 8

The City of Concord began flushing hydrants on Monday, April 8. For several weeks, crews from Concord General Services will flush hydrants in different areas of the city as part of routine maintenance of the City’s water distribution system.


This annual practice flushes out any naturally occurring sediment from the pipes in the system and helps to maintain Concord’s water quality, check the water pressure of the area, and ensure proper operation of distribution system components, such as valves and hydrants.


Depending on the location, flushing will typically start between 4:30 a.m. and 6:30 a.m. and continue through 3 p.m. each weekday.


Water customers may experience low water pressure or discolored water when hydrant flushing occurs in their area. If discoloration occurs, customers are advised to run their tap water on cold until the water runs clear. Customers are advised to avoid doing laundry during their scheduled flushing times.


Hydrant flushing schedules are available on the City’s website at
