Bluffdale water system begins constructing “Triangle Tank”

The City of Bluffdale, Utah, is now constructing a four-million-gallon (4 MG) triangular drinking water tank that Hansen, Allen & Luce (HAL) designed to fit in a tight space. The tank, along with a new pipeline, will improve drinking water service and pressures in the lower parts of the city.

HAL began planning the tank’s size and location in 2016. After finding few sites with the proper elevation and dimensions for a typical circular tank, HAL suggested a distinctive triangular layout to maximize the capacity on a three-sided parcel bounded by two roads and a canal. The site was owned by Jordan Valley Water Conservancy District and is located near the District’s water treatment plant and aqueduct, making the site ideal for connecting to Bluffdale’s drinking water system. In 2019 the City purchased the property and asked HAL to design the facility.

“This tank is triangular due to geographical constraints and took creative engineering and collaboration with multiple agencies to design a vital piece of infrastructure,” said assistant city engineer Trevor Andra, P.E.

Structural Technologies engineered the post-tensioning and Gerber Construction is building the tank, which will be complete at the end of 2020.

“It has been fun teaming with the City of Bluffdale to develop this very interesting solution,” said HAL project engineer Tyler Allen, Ph.D., P.E. “It makes efficient use of limited space and provides the City what they need.”
