The access to drinking water, in particular in the rural areas and semi-rural in Ivory Coast, constitutes a paramount factor in economic development, the improvement of the standard of living of the populations and their stabilization. The present study aims to raise the unequal distribution of the water supply points for the area of Daoukro and to make a contribution in the research of the zones favorable with the establishment of the productive water supply points in order to allow a good cover of the water needs. The adopted methodological approach is summarized in two stages: initially design of the chart of the water requirements (the access to drinking water) which highlights the zones of deficits followed by the cartography of the sites of establishment of the future water supply points. The knowledge of the space distribution of the population and amongst water supply point by locality made it possible to calculate the access to drinking water of the populations. The analysis of the chart set of themes of the storage areas reveals that nearly 80% of the total surface areas are occupied by zones favorable to the existence of groundwater. The various suitable zones with the establishment of work to large flows were charted and more than 150 sites favorable to the future establishments were selected.

Abstract
The access to drinking water, in particular in the rural areas and semi-rural in Ivory Coast, constitutes a paramount factor in economic development, the improvement of the standard of living of the populations and their stabilization. The present study aims to raise the unequal distribution of the water supply points for the area of Daoukro and to make a contribution in the research of the zones favorable with the establishment of the productive water supply points in order to allow a good cover of the water needs. The adopted methodological approach is summarized in two stages: initially design of the chart of the water requirements (the access to drinking water) which highlights the zones of deficits followed by the cartography of the sites of establishment of the future water supply points. The knowledge of the space distribution of the population and amongst water supply point by locality made it possible to calculate the access to drinking water of the populations. The analysis of the chart set of themes of the storage areas reveals that nearly 80% of the total surface areas are occupied by zones favorable to the existence of groundwater. The various suitable zones with the establishment of work to large flows were charted and more than 150 sites favorable to the future establishments were selected.

Abstract: (french)
L'accès à l'eau potable, notamment dans les zones rurales et semi-rurales en Côte d'Ivoire, constitue un facteur primordial dans le développement économique, l'amélioration du niveau de vie des populations et leur stabilisation en zone rurale. La présente étude a pour objectif de relever l'inégale répartition des points d'eau dans la région de Daoukro et d'apporter une contribution dans la recherche des zones propices à l'implantation des points d'eau productifs afin de permettre une bonne couverture des besoins en eau de la région. La démarche méthodologique adoptée se résume en deux étapes : d'abord la conception de la carte des besoins en eau qui met en évidence les zones de déficits suivie de la cartographie des sites d'implantation des futurs points d'eau. La connaissance de la répartition spatiale de la population et du nombre de point d'eau par localité a permis de calculer l'accès à l'eau potable des populations. Les différentes zones convenables à l'implantation d'ouvrage à gros débits ont été cartographiées et plus de 150 sites favorables aux futures implantations ont été sélectionnés.
