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 is directly tied 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.

The startup and testing process for the tank and pump station began in the middle of September. The tank will be filled with potable water and leak-tested. Shortly after, the pump station will go through a series of tests. All water quality and mechanical tests must pass before delivering water to customers. The overall start-up process is expected to last about six to eight weeks. Site work, such as the access road and fencing, will be installed as space is freed up to perform this work.
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
- Commissioning
