Groundwater in Burkina Faso is used mainly for drinking water supply, particularly for small supplies in rural areas and smaller towns. The second city of Bobo Diolasso, which lies on a moderately productive aquifer, relies relatively heavily on groundwater. The capital Ouagadougou, lying on the relatively low productivity basement aquifer, is largely dependent on surface water, but some 15% of its water supply comes from groundwater, which is particularly important in the dry season. | Groundwater in Burkina Faso is used mainly for drinking water supply, particularly for small supplies in rural areas and smaller towns.
