Fire Hydrant Maintenance

Fire Hydrant Maintenance
The City of Bismarck Public Works Department conducts fire hydrant maintenance in the fall of the year.  Dates and locations of the maintenance areas are published in the Bismarck Tribune and listed below.

 When a worker fully opens a fire hydrant for the flushing process, the following are checked and recorded: 
  • Visible and audible leaks 
  • Proper operation of valve

Hydrant testing hours are from 8:00 am – 4:30 pm.

  • Hydrant maintenance may result in rusty water.
  • Customers are advised not to wash clothing during this time until their water clears.
  • One way to help clear the water is to run lawn sprinklers.
