In order to minimize false alarms from acoustic detection devices for leakage from water distribution system in Beijing City, field signal decay experiments were conducted and a decay model for signal propagation in pipeline was constructed. Meanwhile, data from the detection devices and field examination were collected. A recognition model for leakage detection signal was developed using genetic programming method to provide support for helping leakage examination and improve the use efficiency of pipeline leakage detection system.
