ABSTRACT
Leak detection of water distribution networks is a problem that arouses theresponsibleauthorities for distribution all around the word. The reason, which involved researchers representing various disciplines to try to find a solution to the problem by implementing efficient devices in this field.Distributions networks are being degraded over time, which can cause leakage.To detect a leakequipment and techniquesare needed. They are constant progress with the development of technology. In this paper, the CWT (continuous wavelet transform) wassuggested as a technique for detecting and locating leaks in water distribution networks. The treatment using the CWT technique was foundas thebest solution for confirmation of the presence of a leakafter trying different signal analysis tools such as transforms (FFT, STFT, etc ....). The application was carried out in the laboratory with a short channel hybrid prototype (a part of steel followed by a part in PVC). Validations tests have shown the effectiveness of the method.
