| Abstract | Acoustic leak detection methods, in particular leak noise correlators, were studied to determine their effectiveness for locating leaks in plastic water distribution pipes. Also the potential of three alternative non-acoustic methods was evaluated. The study involved field tests at an experimental leak detection facility were several leak types could be simulated under controlled conditions, e.g., flow rate and pipe pressure. Blind tests were performed in collaboration with professional leak detection teams to evaluate commonly used procedures and equipment. Extensive parametric tests were also performed by the research team using a modern vibration measurement and analysis system. The characteristics of leak signals and the effect of several parameters on the accuracy of the cross-correlation method were evaluated. The study demonstrated that leaks in plastic pipes can be located using acoustic equipment - however, it is recommended that several modifications be made to equipment and field procedures to improve their effectiveness. Non-acoustic methods were found promising. |
