An effective leak detection method is one of the most demanding techniques for the management
of water distribution systems. A leak detection scheme with pressure wave analysis using a rapid
manipulation of hydraulic boundary conditions is not always suitable owing to substantial pressure
variation, which can result in undesirable consequences for pipeline systems. The introduction of a
relatively small pressure pulse through a regulated pressure generator can substantially diminish
the potential damage of high- or low-pressure surges. Wave reflection due to the leakage boundary
condition can be useful for predicting the leak location based on the time-domain reflectometry
of the pressure signal. Further elaborate analysis for leak detection can be performed using wavelet
analysis of the pressure signal, which provides leak response features in the time/frequency
domain. Two distinct experimental conditions were employed to illustrate the impact of resonance
on the hydraulic structure, such as a pressurized tank. The developed method demonstrates
the potential of leak detection in a laboratory-scale pipeline system.
