In a world more and more marked with urbanization and then exposed to high risks of increasing yearly population growth, water has hold a paramount place. Water has then become a more and more vital need for people. This fact requires an important consideration in West Africa in general, and in the Nikki district in particular. Despite efforts over years for the mastery of techniques in setting up water fountains, an important part of the population of the Nikki district still lack water. The objective of the present research work is to work out those water fountains in order to evaluate their spatial distribution and their functioning. The methodology used here is exclusively based on the use of attributive and spatial data. To reach the goal of the present study, the Thiessen polygon has been generated. The obtained results have come together to display their spatial distribution and their functioning as well. The average rate of water provision in the district of Nikki is 57.2%, which is below the 67% norm. Only of the seven precincts that make the Nikki district have an average rate of water provision reaching 85%, which is largely beyond the norm. From those data, one can learn that water fountains are unevenly distributed on the land of the Nikki district. This must be improved in order to provide the population with potable water on short distances and with less waste of time for them.

Abstract
In a world more and more marked with urbanization and then exposed to high risks of increasing yearly population growth, water has hold a paramount place. Water has then become a more and more vital need for people. This fact requires an important consideration in West Africa in general, and in the Nikki district in particular. Despite efforts over years for the mastery of techniques in setting up water fountains, an important part of the population of the Nikki district still lack water. The objective of the present research work is to work out those water fountains in order to evaluate their spatial distribution and their functioning. The methodology used here is exclusively based on the use of attributive and spatial data. To reach the goal of the present study, the Thiessen polygon has been generated. The obtained results have come together to display their spatial distribution and their functioning as well. The average rate of water provision in the district of Nikki is 57.2%, which is below the 67% norm. Only of the seven precincts that make the Nikki district have an average rate of water provision reaching 85%, which is largely beyond the norm. From those data, one can learn that water fountains are unevenly distributed on the land of the Nikki district. This must be improved in order to provide the population with potable water on short distances and with less waste of time for them.

Abstract: (french)
Dans un monde de plus en plus soumis à l’urbanisation, exposé ainsi à des risques croissants avec une population galopante au fil des années ; l’eau occupe une place primordiale. Les besoins en eau deviennent ainsi de plus en plus vitaux. Ce constat requiert toute son importance en Afrique Occidentale en général et dans la commune de Nikki en particulier. Malgré des années d’efforts de maîtrise consacrés à la mise au point des techniques et à la réalisation des points d’eau, une frange importante de la population de ladite commune continue de souffrir de la rareté de cette ressource. L’objectif que vise cette étude est de faire l’inventaire de ces points d’eau afin d’analyser leur distribution spatiale et leur fonctionnalité. La démarche méthodologique utilisée est exclusivement basée sur l’utilisation des données attributaires et spatiales. Pour atteindre l’objectif de la présente étude, le polygone de Thiessen a été généré. Les résultats obtenus concourent à faire connaitre leur distribution spatiale et aussi leur fonctionnalité. Le taux moyen de desserte de la commune de Nikki est de (57,2%), ce qui est en dessous de la norme qui est de 67%. Deux seulement des sept arrondissements que compte ladite commune ont un taux moyen de desserte qui atteint 85%, ce qui est largement au-dessus de la norme. Ces résultats montrent que les points d’eau sont inégalement répartis sur le territoire de la commune de Nikki. Cet état de chose mérite d’être corrigé afin de permettre à la population de s’approvisionner en eau potable, sans parcourir une longue distance et aussi sans aucune perte de temps.
