Abstract: Many programs and projects for water resources management are initiated in Senegal to satisfy an increasing demand for water, especially in rural areas. The lack of sufficient funding requires that these projects be spread over time. Therefore, prior to any technical or economic feasibility study, it is necessary to identify the higher priority areas. This study presents a multicriteria analysis for ranking rural subareas in Senegal, in particular in the region of Diourbel, in terms of prioroities of water supply needs. After having identified the objectives related to water supply on the regional scale, six quantitative and qualitative priority criteria were defined. These criteria pertain to the available water quality, the available quantity of water for domestic needs, the distance to water distribution points, the availability of water for agriculture, the acceptability of water costs and the development potential of a rural subarea. The achievement of the objective which consists in supporting the cattle farming is however not measured due to lack of data. Indicators are proposed for each criterion based on the data available at the time of the study. Criteria weights were obtained from various water resource management stakeholders in Senegal. It’s a region essentially feed by mediocre quality groundwater and where the lack of good water quality is recurrent. Our multicriteria analysis leads to the ranking of eight districts of the Diourbel region in terms of intervention priority. A sensitivity analysis enabled us to evaluate the effect of the criteria weights on the districts ranking. Our experience with this project has brought forward the difficulties associated with conducting a multicriteria analysis in the Senegalese context, while emphasizing promising application possibilities.
