Fire Hydrant Flushing in Coralville

Fire hydrant

The City of Coralville Water Department will flush fire hydrants north of Oakdale Boulevard in Coralville starting the week of April 11. Crews will begin in the northeast part of Coralville, starting north of Oakdale Boulevard and east of 1st Avenue. Hydrant flushing is expected to last until late May, weather permitting. Hydrant flushing locations will be updated weekly as crews progress through Coralville.

As a result of hydrant flushing, residents in the vicinity may notice water running down the street, or a temporary discoloration of their water which does not affect the water safety. In the event of discolored water, run cold water from a faucet until the water clears.

Hydrant flushing is an annual water system maintenance practice that moves water through the pipelines fast enough to remove sediment, and allows the City to service fire hydrants and check water pressure. For more information, please contact the Coralville Water Department at 319.248.1770 or the Utility Billing Department at 319.248.1715.



  • Week of April 11: Crews began to work north of Oakdale Boulevard, in the northeast side of Coralville, working in the area of Welsh Village. Crews will then move west toward Highways 965 / Coral Ridge Avenue staying north of Oakdale Boulevard.
  • Week of May 22: Crews are flushing hydrants between 1st Avenue and 12th Avenue north of Oakdale Boulevard. Flushing hydrants in this area will take roughly one week. Residential area flushing in this area is expected to wrap up mid-week. Then hydrant flushing in the commercial area between Crosspark Road and Coral Ridge Avenue will begin.
  • Week of May 30: Crews expect to flush hydrants between Holiday Road and I-80, west of 12th Avenue to Coral Ridge Avenue.
