This study is part of a search for sustainable solutions for access to drinking water in rural areas of Côte d’Ivoire, where boreholes in bedrock areas are the main source of drinking water supply. The objective is to statistically analyse the flow rates (Q, in m3/h) of water boreholes in the N’zi-Comoé region in order to assess their variability, distribution and relevance in characterising the aquifer potential in bedrock environments. To do this, descriptive statistics and the Shapiro-Wilk and Chi2 statistical tests of normality were used. This approach yielded relevant results, namely an average flow rate of 5.71 m3/h, which is lower than the standard deviation, and a coefficient of variation of 131%. These values indicate a high degree of heterogeneity in flow rates in the N’ZI-Comoé region. This highlights the discontinuous nature of the aquifer tapped for drinking water supply not only in the study area but also in the bedrock environment in Côte d’Ivoire.
