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.
