Tehaleh Water Storage Tank
Pinnacle Ridge Reservoir
Construction is underway for a new Tacoma Water storage tank and pump station on a two-acre parcel of land in the Pinnacle Ridge neighborhood of the Tehaleh community. This project ensures water service reliability, including adequate supply for firefighting and other emergencies. A vital component of this project is to control and maintain water pressure, enhancing the comfort of the community.
Tacoma Water determined the need for this storage tank during the planning of the Tehaleh master-planned development. Therefore, the timeline directly ties to the community’s growth. The tank will be approximately 90 feet tall and 106 feet in diameter, with a capacity of five million gallons.
To minimize the impact on the neighborhood, the site for the tank is on existing utility-zoned property. Tehaleh developers helped select the location during the initial design of the community for its proximity and accessibility.
- November 2023 Project Update
The Booster Pump Station arrived on Friday, October 13, 2023. The pump station is very large, weighing approximately 80,000 pounds. One of the photos shows it being placed next to the tank. In November, connections to the pump station will be made. Additionally, work will begin to apply coatings to interior pipe and tank walls/roof and then to the outside of the tank walls/roof. The coatings require certain temperature conditions; therefore, heaters will be operated to maintain the appropriate climate. Generators will power the heaters, which may create ambient noise from the site. The exterior tank coating will be a green color named “Clover,” agreed upon with the Homeowners’ Association when the tank was being designed.
Process for design and construction:
- Clear property and begin site work
- Install water main
- Construct a storage tank
- Install pump station
- Construct communications building
- Complete site work
- Testing and start-up
