The design phase considered sliplining, CIPP, HDD and even open-cut installation. Ultimately HDD was chosen and the paper will cover the decision-making process, considerations for each method and the factors that led to our decision.


8:25 AM .......................................................WM-T4-02Do It Yourself Water Main Pipe BurstingRussell Colbath, City of MonroeA case study of how the City of Monroe, North Carolina, developed an internal water main pipe bursting program. As the only municipality in North Carolina to self-perform water main pipe bursting, the program has allowed Monroe to reach its replacement goals in an efficient, flexible and cost-effective way.

Irrigation SiphonAdam Sedgeman, FRP Construction LLC; Max Schmidt, Orchard Mesa Irrigation District; Mo Ehsani, FRP Construction LLC; Marvin Murphy, FRP Construction LLC This project consisted of the rehabilitation of a 54-in. steel irrigation line in a remote location with steep terrain. In addition, the pipe had to be rehabilitated through the winter months in Colorado. The owner was very pleased with the fiber-reinforced polymer technology utilized on this project.


9:15 AM .......................................................WM-T6-04The Evolution of Carbon Fiber CIPP (CFCIPP) for Small Diameter Potable Water & Fire Suppression SystemsIan Lancaster, Aegion; Medhi Zarghamee, Simpson Gumpertz & HegerIn 2013, engineers and material scientists from SGH and Aegion embarked on a development program for the Arizona Public Service Company. This development surrounded the use of carbon-fiber reinforced CIPP to rehabilitate and renew aging high pressure potable water/fire suppression system at a major facility in the southwestern United States.

Track 1: MicrotunnelingTrack Leader: Jack Burnam

9:15 AM .......................................................WM-T1-04Reducing Risks of Microtunneling from the Pipe’s PerspectiveCyrill Althuser, Jackcontrol AGRisk analysis and mitigation are essential in microtunnel and pipe jacking applications. A microtunnel consists of many pipes being pushed through the ground, therefore, the pipe design requires special attention. This paper discusses the most important aspects to make the risk more bearable to all involved parties.
