Renewal of aging underground infrastructure is a major challenge that municipalities in North America face every day. Traditional replacement or renewal of these underground utilities uses open-cut excavation methods that can be disruptive to everyday life of citizens and expensive, particularly in built-up areas and in projects with difficult ground and site conditions. In contrast, trenchless technologies use innovative methods, materials, and equipment that require minimum surface excavation to renew and construct aging underground infrastructure. These new methods are considered to be more safe, cost-effective, efficient and productive than conventional open-cut projects. However, to select trenchless technologies in utility design, consulting engineers and utility owners need to compare their costs with open-cut methods.
