Abstract
Currently, according to the National Sanitation Information System (SNIS), water distribution companies in Brazil lose, on average, more than a third of their treated water. Most of this due to real losses, as leaks at the operating units along the supply system. To change this scene faced by water supply companies, it is necessary not only to explore the detection methods, but also to characterize the vibro-acoustic signal generated by the leak. This work looked for to develop a better understanding of the signal characteristics, and the natural frequencies of the system, also analyzing the influence of the pressure, the leak diameter, and the pipe material in the propagation of the excitation. The interest case was performed experimentally and some results were compared with a numerical analysis.
