The difficulties of access to drinking water in the municipality of Kandi are especially related on the unequal distribution of the hydraulic infrastructures and the frequent breakdowns of some of these works. This bad spatialization of the hydraulic works, added to under information and the low-income of the households decrease the accessibility of the majority of these households to the sources of water of required quality. The objective of this research is to study the accessibility of the populations to the hydraulic works in the municipality of Kandi. In a specific way, it was a question of inventorying the types of works available, of mapping them and of analyzing their spatial distribution. The adopted methodological approach is based on the one hand on the data collected starting from data sheets of the regional service of hydraulics of Alibori and an investigation of ground having allowed to collect the geospatial data bound to the works. On the other hand, the polygon of Thiessen was generated from the software Arc Gis 10.3 to arrest better the spatial cover of its hydraulic infrastructures. The obtained results allowed to appreciate the degree of accessibility of the populations to the hydraulic infrastructures in this municipality.
