Tucson Water’s Fire Hydrant Locking Program

In October 2010, Tucson Water began to lock fire hydrants in order to achieve the following goals:

  • deterring water theft
  • ensuring the water quality of the water system
  • standardizing this program with those of other major Tucson–area water providers
  • securing the water system against potential terrorist threats

Fire hydrants are engineered and installed by Tucson Water primarily for fire department use. An additional benefit of public fire hydrants is that they can be metered and used to temporarily supply construction water.

Licensed contractors can use any Tucson Water fire hydrant, locked or unlocked, through a rented construction meter from Tucson Water. Contractors can also use permitted privately-owned construction meters on any unlocked fire hydrant.

Please refer to the map on this page for the general location of our locked hydrants. In the coming years, Tucson Water will continue to systematically lock fire hydrants throughout the distribution system.

To rent a construction meter, or to check on the status of a particular hydrant, please visit our New Services counter at Tucson Water, 310 W. Alameda St.  The counter is open Monday through Friday, 8 a.m. to 4 p.m.
