Fusible C-905® Pipe Used for Trenchless Segments
of New Water Transmission Line in Corinne, UT
To accommodate current and projected growth, the City of Corinne, UT recently undertook a project to increase its water capacity. Construction of a new water tank on the east side of the valley required a new pipeline to be built westward to Corinne, traversing under the Brigham City Municipal Airport, Interstate I-15, and the Bear River.

As a result of previous successful crossings under I-15 and the Bear River using Fusible PVC® pipe in neighboring Brigham City, J-U-B specified Fusible PVC® pipe for several critical sections of the new water line where HDD and sliplining were required. Fusible PVC® pipe was specified in the following reasons:
- Beneath the Brigham City Municipal Airport an existing 20" steel casing contained a 12" bell-and-spigot PVC line that needed to be upsized to 16". Fusible C-905® pipe was selected for its ability to maximize flow inside the casing (~70% more flow than the existing 12" PVC and ~30% more than 16" DR11 DIPS HDPE pipe).
- The direct bury portions of the transmission line were designed for bell-and-spigot PVC. Using Fusible C-905® pipe for the trenchless sections allowed the City to maintain material compatibility and simplify connections by stabbing the fused pipe into the gasket pipe and using a restrained MJ sleeve to complete the connection.
- Significant cost savings were achieved on the trenchless sections by minimizing the HDD bore hole size for the crossings under the Bear River and I-15. HDPE pipe would have required a 24" diameter to match the ID of 20" Fusible C-905® pipe. Using the smaller OD Fusible C-905® pipe on the I-15 crossing allowed the steel casing to be proportionally smaller.
The 930 LF 16" DR25 slipline section underneath the airport took only three hours to install. Operators used backhoes with canvas straps to stroke the pipe in. The HDD section under the river took only a few hours to pull in, with a pull force below 25,000 lbs.
Greg Seegmiller, J-U-B Project Manager, remarked: "Crossing the river could have been a very messy project. Fusible C-905® pipe made it clean and easy for both permitting and construction."
Dave Ormond, Ormond Construction, stated: "Installation of the Fusible PVC® pipe went without a hitch. UGSI treated us professionally and took great interest in the successful outcome of our project. We look forward to using Underground Solutions again."
