AbstractThe National Research Council Canada (NRC) has recently completed a project to assist the City of Montreal in determining the condition of its water and sewer system. NRC staff members reviewed available and future diagnostic techniques for both systems, conducted experiments on corrosion monitoring, CCTV inspection and mechanical inspection methods and provided general scientific advice during the course of the project. This paper describes the results of the review of diagnostic techniques for metallic and pre-stressed concrete pipes. Both older techniques such as water audits and leak detection and new approaches such as acoustic emission monitoring and remote field effect inspection are discussed. Advantages and disadvantages of each technique are tabulated and approaches are suggested for combining the different techniques to provide a complete diagnosis of a water system.
