Résumé
Access to drinking water remains a problem in search of solutions in African countries. In Burkina Faso, more precisely in the rural commune of Korsimoro, water chores persist despite numerous actions undertaken by the State and its partners, hence the need to improve the effectiveness of interventions. This study aims to optimize interventions in the field of drinking water through the use of geo-information tools. To achieve this, data collection was initiated with the National Institute of Statistics and Demography (INSD), the ministry in charge of water, the Bureau of Mines and Geology of Burkina Faso (BUMIGEB) and the authorities of the target municipality. They were used to establish a map of the existing infrastructure for access to drinking water in Korsimoro, to identify localities not served or served below the standard. A multi-criteria analysis with spatial reference based on fracturing density, drainage density, static level, end-of-drilling flow rate and alteration thickness was carried out in order to understand the hydrogeological context. Taking into account the context of each locality combined with their access rates to drinking water made it possible to propose 72 sites to be prioritized during future interventions for greater efficiency. The approach used can be applied in other localities in Africa to optimize interventions in the field of drinking water.
