In the 1980’s and early 1990’s manual drilling in Uganda meant hand augering, using the Vonder rig. It was popular and successful. However, its limited technical capability (i.e. inability to drill laterite) coupled with privatisation, inadequate supervision and competition from small machine rigs meant that it became less popular and had fallen out of use by the late 1990’s. Since then, other improved manual drilling techniques have been introduced by various organisations. None of these have managed to move much beyond testing or piloting. The most encouraging manual drilling initiative today is the training of enterprises in Gulu in a project financed by World Vision. However it is still too early to see whether there will be widespread uptake. Due to the geology and hydrogeology of the country, manual drilling will be possible in some areas only. For Uganda manual drilling is a niche technology, but perhaps highly suitable in some contexts.
