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.

November 2024 Project Update

On Friday, October 18th, Tacoma Water held the Pinnacle Ridge Reservoir and Pump Station Commissioning Celebration. Startup and testing are well underway, and the facility started sending water to customers in late October. The remaining activities at the site include completing instrument and controls testing and finishing a few outstanding construction items.
