Water tanks an important addition to Dome Technology’s scope

Dome Technology is actively expanding its scope of expertise, and one of the most recent storage models added to the catalog is water tanks.

“We have a tank that will save municipalities significant money,” said Dome Technology sales manager Daren Wheeler. “Our building method is just more efficient with less waste. It’s a win for taxpayers.”

City of Shelley
The City of Shelley partnered with Dome Technology for their recent water-tank project.

Dome Technology’s AWWA D115 tank is built with this process: The foundation is established, and an airform fabricated in the exact shape of the finished tank is attached to the foundation and inflated with high-power fans. The vertical stem walls are sprayed with concrete, as is the low-profile domed roof. Post-tensioning tendons are attached to the vertical wall, along with typical reinforcing vertical and horizontal rebar. Concrete is sprayed to embed the tendons.

A polyurea coating is applied to the entire interior, and the domed roof is closed with a hatch and ladder up the side for access. The tank is then disinfected and ready for use.

City of Iona water tank
Construction is nearing completion on a water tank for the City of Iona.

Dome Technology liquid storage tanks can be built in any weather conditions and compete with AWWA D110 tanks in cost and construction time.

The difference in Dome Technology’s liquid storage tanks shows up in the pre-stressing. Instead of wrapping the post-tensioning wire around the outside, it is embedded in the tank’s walls, resulting in a seamless, robust structure.
