Tucson Water has identified certain locations in the distribution system that are experiencing difficulties with water pressure and/or volume when construction water is drawn from local hydrants. These hydrants represent only a very small fraction of the total number of hydrants in the Tucson Water distribution system. Use of these identified hydrants for construction water may result in:

• Insufficient water available for fire flow
• Potential for backflow into the distribution system
• Unacceptably low pressure to area customers

To address these issues, Tucson Water is instituting a new program to eliminate the use of construction water from certain fire hydrants in these areas.

Tucson Water will be placing green markers/rings on the front of each of the affected fire hydrants (see illustration above). Construction water will no longer be available from these designated hydrants.
