Leaks in water pipelines cause unnecessary waste of limited resources, thusthe necessity of leakage prevention and detection.The experience of water distribution companies shows that the reduction ofleakage and the preservation of a low leakage level can be achieved with astrategy that requires a loss analysis followed by leak detection andlocation survey.Effective techniques of leak detection by acoustic emission have beendeveloped and tested and this paper describes the experience and resultsobtained with the application of these techniques in the last fifteen yearsin several water systems including but not limited to those managed by ASMBRESCIA S.p.A. in Italy.
