Acoustic Based Data Acquisition for Leak Detection of Water Distribution Networks

This data acoustic signals recorded from real and buried water distribution networks (WDNs) in Hong Kong. The signals were collected from about ninety leak sites throughout a period of a year using three different non-destructive technologies, namely noise loggers, hydrophones, and micro-electro-mechanical-system (MEMS) accelerometers. The leak signals were collected when leakage is reported, while the no-leak signals were recorded when a previously visited leak site is repaired. Both leak and no-leak signals were recorded from metal and non-metal pipes. The technologies used to acquire the signals did not change the conditions under which the water was supplied to households.
