30 T R E N C H L E S S T EC H N O LO GY C A N A DA FA L L 2018 How did you get started in this particular niche? I took a curious interest in trenchless technology early in my career on the suggestion of a professional mentor of mine, Ron Schwark. I recognized how trenchless technolo - gies provide an alternative option to traditional open cut- and-cover. I found it remarkable how this process could lessen the impact on the social , built and natural environ- ments. I wanted to be a part of it all and make positive change. What has changed since you started in this sector? Over the years, the biggest change has been innovation. In addition, new construction techniques, materials, and equipment have emerged because of the need to overcome industry challenges. How has technology changed your work? Innovation has led to the development of different pro - cesses. When I started my career, horizontal directional drilling included the installation of 4- to 305-mm pipes, pulled underground for a distance of 91 m. Now, we have installed pipes up to 1,524 mm in diameter, for distances in excess of 122 m. Mechanical spot repair and grouting joints are starting to be a viable option for sewer repair. Last year, industry publications announced the global re- habilitation of more than $2.5 billion of sewer pipes using the CIPP technique. How do you see your projects changing in the future? Industry findings state that contractor and consultant capabilities are growing throughout the United States and Canada. As more opportunities to improve sewer lines pres- ent themselves, the market share becomes larger. Instead of open-cutting sewers, which has been the predominant replacement method, more municipalities are discovering how trenchless methods allow greater work accomplished at increasingly competitive prices. Now that trenchless technologies have matured, we have a variety of methods and materials from which to choose. Are there other uses for trenchless technology other than sewage system rehabilitation? Trenchless technologies apply to a wide variety of new installat ions as well as rehabilitat ion of exist ing inf ra - structure. While there is always an opportunity for sew- ers to be upsized or repaired by open cut , other tech - nologies are advancing and becoming common . If the industr y properly monitors deteriorat ion in their piped networks , they can implement repair prog rams at sched-
