Abstract
As with other buried infrastructures, more portions of the trunk sewers in Canadian municipalities approach or exceed their design service life each year. Large size trunk sewers are usually installed below all other buried utilities under city streets. Collapse of a trunk sewer will not only cause severe interruptions to service and traffic, but also pose repair challenges to the engineers. Based the discussions and presentations at a forum sponsored by the National Research Council of Canada and attended by representatives from 12 municipalities across Canada, this paper summarizes the conditions of the aging trunk sewers, and the current state-of-practice in trunk sewer maintenance, inspection and rehabilitation techniques. Other relevant information, such as pipe sizes, types and materials, maintennce costs and distress statistics, is also presented.
