The hydrogeological problems posed by the KANJIYA borehole are multiple. Kanjiya is a district located in the commune of Bipemba in the town of Mbujimayi. Although a network of 24 boreholes has been established in the town of Mbujimayi, the KANJIYA borehole has never been studied as a whole from a hydrogeological point of view. It was therefore necessary to categorise the water table, determine its hydrodynamic parameters and study its behaviour during pumping tests. The data was collected by lithological description of the cuttings taken every metre from the sediments traversed by the borehole (the rotary) with a planned depth of 117.60 meters. The data from the flow tests and the existing geological and hydrogeological knowledge allowed us to categorise the water table and its hydrodynamic parameters and to reconstruct the lithological successions of the hydrogeological units. It has been shown in this work that KANJIYA belongs to a zone of the Bushimay system and the vertical lithological section shows the succession: clayey sand, more or less soft sandstone, weathered limestone, hard limestone, hard limestone, fissured limestone, cavity and hard limestone. The water table is encountered in a fissured limestone at a depth of 84.50 meters; its behaviour during pumping tests shows that it is semi-captive. The hydrodynamic parameters are favourable for exploitation at a flow rate of over 80 m3 per hour. A low drawdown, a slow descent of the hydrostatic level and a rapid rise in the water table when pumping stops would explain the influence of a more altered and fissured aquifer.
