The City of Bismarck Public Works Department will be conducting fire hydrant maintenance from Xavier St to State St and I-94 to Boulevard Ave the week of August 16-20. Hydrant maintenance in these areas 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. Hydrant testing hours are from 8:00 am to 5:00 pm.
