Abstract: In order to provide references for quick leakage detection and location in water supply indus-try,the leakage detection methods based on hardware and model algorithm were compared. The applica-tion 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 principleand electric signal transmission. These methods have high accuracy,but high time and energy consump-tion cost. The model algorithm-based leakage detection technologies are based on the node pressureand flow characteristics of pipe networks. The possible leak points can be quickly located by the optimi-zation algorithm obtained by minimizing the difference between model simulation value and measuredvalue,but there is a certain deviation in the location. It is suggested to combine the two leakage detec-tion methods to maximum their advantages and provide ideas regarding rapid and accurate leakage de-tection for waterworks. Close-
