Contractor Installs Largest Diameter Solid Wall HDPE

“[The project] will provide public safety in urbanized areas and eliminate the dangers of an open canal.”
—Mike Cottle, Project Manager, BHI

BHI is enclosing the Steinaker Service Canal near Vernal, Utah, into a 78-in. pressurized pipeline, the largest diameter solid wall HDPE pipe ever installed in the U. S. The installation includes more than 15,000 linear ft of 78-in. HDPE pipeline with air valves, manways, drains, turnouts, screening structures, electrical and instrumentation, a new access road and other related work.

Owned and maintained by the Uintah Water Conservancy District, the canal carries approximately 250 cu ft per second of irrigation water to users in the Ashley Valley area, which is delivered through 50 turnouts. Construction started last fall and will be complete in April, in time for the start of irrigation season. The project will help with drought resiliency by saving the water sent down the canal.

“This canal runs roughly 12 miles and loses around 5,000 acre-feet of water yearly, or 25% of releases from the reservoir,” says BHI project manager Mike Cottle.


Brown and Caldwell Design Ion Exchange Facility to Pull Contaminants From Groundwater

The South Adams County Water and Sanitation District has hired Brown and Caldwell to design an 18-million-gallon-per-day ion exchange (IX) process at its Klein Water Treatment Facility in Commerce City, Colo. IX treatment is currently the most effective technology in removing PFAS/PFOA—known as forever chemicals—by means of a highly porous resin that acts as a powerful magnet to adsorb and hold onto the substances. The new system will consist of seven IX treatment trains, a 375,000-gallon equalization tank and six vertical turbine pumps to feed the IX trains from the district’s 13 groundwater supply wells. Scheduled for completion by the end of 2026, the new IX treatment facility will provide a peak combined capacity of 26 MGD.
