Muni Water Company has been managing the potable water infrastructure and providing clean and safe water in Utopia Valley for 100 years. During routine quality control inspections they discovered a compromised 1,000 foot section of 12-inch pressurized water main. Their primary concern was this pipeline ran underneath a dinosaur fossil preserve. Since trenching the protected environment wasn’t an option they needed a trenchless solution that could handle the 150PSI water pressure and be capable of traversing a 90 degree bend. Their other major concern was the common seismic activity from the fault line 75 miles west.

The Advantage Reline team consulted with Muni Water Company and recommended Primus Line for this project. Primus Line was the solution of choice as it met all the specifications and requirements. Primus Line, a trenchless pipe rehabilitation liner, is able to handle high pressure pipelines, traverse 90º bends, and withstand considerable soil movement without risk of sheer. With Primus Line capable of providing 50+ years of usable life and the Advantage Reline guarantee, the choice for Muni Water Company was clear.

With only 2 small access pits needed, one at each end, there was no disruption to the adjacent highway traffic at the north pit location and the small south access pit kept the preserve untouched. Due to the experience of the Advantage Reline team, the project started on time and was completed within 2 days – with the water supply out-of-service for only 8 hours. When asked about the project after completion, Michael B., with Muni Water Company said: “Working with Advantage Reline was incredibly easy. They are true experts in their field.”
