Pre-Localization Approach of Leaks on a Water Distribution Network by Optimization of the Hydraulic Model Using an Evolutionary Algorithm

Abstract

The sustainable management of water distribution networks is a crucial challenge especially in emerging countries. The distribution networks have very low efficiency with very high levels of leaks. Locating and prioritizing of water leakage areas becomes a main concern for public services, to optimize the use of resources and improve constancy of supply. A decision support approach was proposed to locate areas with higher leakage rate. It is based on the resolution of the FAVAD equation (Fixed And Variable Area Discharge). The determination of FAVAD parameters enables to simulate the quantities and the location of the leaks, through the use of genetic algorithms coupled with hydraulic modeling and the geographical information system (GIS).
