The Ministry of Energy and Mines of Madagascar in cooperation with UNICEF embarked on a drinking water project in the Mahajanga region in 1999. In this study, the climatological parameters were used to assess the recharge potential of groundwater, and the hydrogeological parameters using pumping test data were evaluated. In addition, possible effects of the project on socio-economic aspects of rural development were explored. The results showed that 24 % of the 38-drilled boreholes was negative (no water or dry hole) and 76% was positive. However, only 80 % of the positive boreholes had highly efficient pumping specific capacity. The failures observed in some of the boreholes highlight the importance of hydrogeological information in such a project. Use of such information may increase the efficiency of borehole specific capacity (i.e. stability of borehole specific capacity) as well as the number of operational boreholes in the area. Currently, at least 35% of the population have access to safe drinking water and are thus free of waterborne diseases. Such access to water quality will lighten the Government's social responsibility and increase the agricultural productivity of the farmer.
