Probability of simultaneous multiple leakages at sections of water networks in the process of localization of hidden water leaks

Hidden leaks from water supply networks account for 50% to 90% of total leakage losses. The presence two or more simultaneous in a section the network significantly reduces accuracy locating hidden leaks. method independent Poisson events and hypothesis stationarity, absence consequences, ordinariness are used probabilistic description problem multi-leakage networks. analytical dependence probability multiple leakages on specific annual emergency rate site, its length duration localization repair period is obtained. A generalized semi-empirical equation was obtained estimating maximum permissible depending site given probability.
