Spanish Fork–Santaquin Pipeline | Central Utah Water Conservancy District
The Central Utah Water Conservancy District (CUWCD) is completing one of its most significant regional water delivery projects: the final segment of the Spanish Fork–Santaquin Pipeline. The system will ultimately deliver more than 23,000 acre-feet of water annually to support fast-growing communities across South Utah County.
Through a competitive bid process, Iowa Trenchless was selected to install three critical tunnel sections required to carry a new 60-inch diameter steel pipeline beneath major transportation corridors.
Project Scope & Crossings:
- 265-foot tunnel beneath Interstate 15
Completed using an Akkerman 660 TBM equipped with an x-bar cutting head, this installation navigated mixed soils of clay, silty sand, gravel, and cobbles while maintaining uninterrupted interstate traffic.
Foreman Lance Atkinson and his crew — Noah Ramsay, Steve Bell, Justin Jungles, Gavin Felder, Brian Krakau, and Avere Doles — delivered flawless execution despite the complex geology. - 200-foot tunnel beneath U.S. Highway 6
More granular, loose soils required a closed-face cutting head to control material inflow. Precise communication between TBM operator Lance Atkinson and pipe jacking operator Steve Bell ensured tight line-and-grade tolerances and a safe crossing. - 120-foot tunnel beneath Union Pacific Railroad
This final segment will complete the trenchless work and pave the way for improved water infrastructure supporting decades of regional growth.
This multisection tunneling effort is essential to CUWCD’s long-term water strategy, enabling a reliable and efficient water supply system for expanding municipalities throughout the region.
