Jordanelle Wastewater Plant
Heber, UT

The Jordanelle Valley Wastewater Treatment facility has a unique look, because of the adopted look for the town and the proximity to the freeway, the city council requested that the treatment plant fit into the theme of the town. In order to accomplish this, the treatment plant is to be designed as farming structures or as barns.

The Jordanelle Plant consisted of a 2 MG original plant with an anticipated 2 MG future expansion. Our responsibilities consist of the full structural design of the treatment plant, including the Headwork’s Building, the Sludge Holding Building and the Process Building. The Headwork’s Building; including a pump station was to be primarily above grade with concrete walls and a steel trussed roof structure.  The Sludge Holding Building is actually two levels and required special design for vibrations due to the equipment to be placed inside the facility.  The Process Building, being the largest building at 2400 square feet with an 80’ open span supporting a 2 ton crane, housed offices, two aerobic basins, two anoxic basins and a four bay pump station and blower room.  All building structures were designed as a concrete or masonry exterior and steel roof systems. 

The unique design parameters require additional creativity in the design process; however the location proved to have additional complications. The building site is in a marshy area with a seasonal high water table. All foundations were designed as either a mat foundation or had piles to support the facility on bedrock, which was only fourteen feet below grade.
