In order to provide references for quick leakage detection and location in water supply industry,the leakage detection methods based on hardware and model algorithm were compared. The application scope and characteristics of the methods were analyzed. The analysis shows that the hardware-based leakage detection methods are developed mainly based on acoustics, optical reflection principle and electric signal transmission. These methods have high accuracy, but high time and energy consumption cost. The model algorithm-based leakage detection technologies are based on the node pressure and flow characteristics of pipe networks. The possible leak points can be quickly located by the optimization algorithm obtained by minimizing the difference between model simulation value and measured value, but there is a certain deviation in the location. It is suggested to combine the two leakage detection methods to maximum their advantages and provide ideas regarding rapid and accurate leakage detection for waterworks.
