Fort Douglas 3 Million Gallon Storage Tank


About the Project

Salt Lake City Public Utilities Department owns and operates the Fort Douglas Tank, which provides drinking water and fire protection storage for the north end of the East Bench High Pressure Zone.

The existing Fort Douglas Tank has a stated capacity of 1 million gallons (MG). During periods of peak summer demand, the existing tank cycles through its storage capacity two or more times daily. The city determined that an additional new 3 MG storage tank would be needed to meet the current and future water demands for the city. The new 3 MG storage tank is currently under construction and located adjacent to the existing 1 MG tank.

Rocky Mountain Power will be upgrading their high voltage line infrastructure to minimize wildfire risk during the month of June 2022.  Loss of power is not anticipated during this time; however, they will be working in proximity to the Fort Douglas Tank Project.  Rocky Mountain Power’s work may impact trails and access.  For more information regarding work on the power lines please contact Rocky Mountain Power directly.

Crews are currently working on the interior of the tank. They will be testing the tank and pipelines in the next six to eight weeks. Backfill, electrical work, retaining walls. landscape restoration, and access road improvements will take place after the testing is complete, and is expected to last through August. 


Please stay clear of construction areas and follow all posted designation trail signs.

The existing and proposed tank is located on US Forest Service land. The necessary environmental documentation and approvals between Salt Lake City and the US Forest Service for the proposed tank project are complete. 


Consistent with the City's  core values, the new Fort Douglas Tank Project is designed with an eye to sustainability. Construction materials were selected to maximize tank design life and to minimize maintenance and energy use.

Landscape and trail restoration efforts include measures to improve drainage, stabilize and mitigate erosion, and restore native vegetation.
