"The massive Interstate 80 project to replace bridges and rebuild interchanges and roadway along this major east-west corridor has prompted other utility improvements along the way.One of these—in South Salt Lake, Utah—involved replacement of an aging 18-inch asbestos-cement water transmission line beneath Roberts Avenue. As part of the Utah Department of Transportation’s State Street to 13th East Utility relocation project, the line was one of several water utilities targeted for upgrading due to potential settlement during the road project.
Pipe bursting was selected as the pipe replacement technology by the city and the engineering consultant, Horrocks Engineers (Pleasant Grove, Utah). The reasons were quick installation and the tightness of the site, and because asbestos-cement pipe can be problematic if excavated and removed. Pipe bursting would simply force the pipe fragments into the surrounding soil.

Fusible PVC pipe was chosen for the replacement pipe because of its reduced material costs..."
