Approximately 256 million people in rural Africa live without access to safe water supplies, in areas that could be appropriately supplied with water from hand-pumped boreholes. Groundwater is generally a readily available source of water throughout Africa. However, high borehole construction costs are slowing progress on increased access. These high costs are largely a result of using drilling equipment with specifications that are greater than those required for the vast majority of boreholes needed in Africa. Using high cost machinery and support equipment leads to high borehole costs, which in turn results in fewer boreholes being drilled. The smaller volume of work per drilling rig creates inefficiencies in equipment usage, and results in increased overheads, driving up costs dramatically.
