In order to enhance both the water supply efficiency and operation management level,the advance of the technique of the leakage monitoring and control of pipeline system and the major problems therein are sorted out from the aspects of the technique and equipment for fault monitoring of pipeline network,the method of leakage positioning model,signal identification and algorithm optimization,health maintenance and intelligent management,etc. for the statuses of the leakage control of water supply pipeline systems at home and abroad,and then the applicabilities of all the methods to detect leakage of pipeline network are analyzed as well. On the basis of this,the key problems those are worth to be solved for the leakage control of the pipeline network and the relevant tendencies are put forward from the perspective of practicality as followings：（ 1） for the monitoring and early-warning of the leakage,the leakage monitoring and control-oriented optimal layout for the network formation of pipeline network and the relevant quick early-warning technique are necessary to be studied;（ 2） for the small leakage positioning model,the identification of leakage region and the analysis of inverse problem of hydraulics-based active detection theory and method are necessary to be studied;（ 3） for the development of the detection equipment,the key equipment based on the new techniques of ground-penetrating radar,optical fiber sensing,endoscopic inspection robot,etc. is necessary to be emphatically developed;（ 4）for the health maintenance and intelligent management of pipeline network,the zoning method for those regions of independent measurement within complicated pipeline network and the techniques for health evaluation and optimal maintenance of pipeline network are necessary to be studied as well.
