New Signal Butte Water Treatment Plant Meets Goal of Sustainable Water Supply into Future

Sundt Construction, Inc. recently celebrated the completion of the city of Mesa, Arizona’s Signal Butte Water Treatment Plant. The $103.6-million water treatment plant treats Colorado River water supplied via the Central Arizona Project canal to drinking water standards.

“Our team remained dedicated to deliver water prior to peak summer demands under a compressed schedule and worked very hard to accomplish this project in a safe and timely manner,” said Rob Infantino, Sundt’s project director. “The project was located in the middle of a large neighborhood, and our project team considered all of its surroundings when planning work activities.”

The project included the construction of an operations building, raw water flow control and PH adjustment facility, ballasted flocculation facilities, ozone generators, ozone contactors, deep-bed biological filtration facilities, solids residuals facilities, mechanical dewatering facilities, chemical buildings and improvements to the existing electrical building and standby power generation. Site improvements included roads, parking, drainage facilities, fencing, landscaping and site lighting.

The 24 million gallon per day facility was built to accommodate future ultimate expansion capacity of 48 MGD. As development in southeast Mesa continues to increase, the Signal Butte Water Treatment Plant allows the city to meet its goal of a sustainable water supply well into the future.

Serving as the construction manager at risk, Sundt started work on the site in the summer of 2016. The company self-performed much of the work on the project with its own skilled craft workforce.
