To achieve our goal we'v relied in this study on the descriptive analytical method, and we used several techniques in treating The data gathered, we presented it in pictures, maps and graphic forms, figures, tables, diagrams, schemas, and profiles. The study have showed several important results : _water distribution system grows and increases with the growth of population and urban expansion. _The increasing demand of water requires a process of finding and diversifying water sources of both ground and surface sources. _the urban characteristics developed through different periods in different directions forming heterogeneous tissue, that has affected the WDS on its length and type. _city is supplied with water depending on both repression and gravity. _city main source of water is the surface water from the Dam of BeniZid. _various technical and administration problems found in the site along the WDS. _creation of a Database using GIS could help in solving problems.otherBiologie : populationInterventionGISOther
