Rural water supplies: comparative case histories from Nigeria and Zimbabwe

Abstract Two rural water supply projects based on groundwater sources are described and compared. One in Nigeria aimed to provide yields of greater than 1 l/s using electric submersible pumps to villages and towns with populations from 2000 to 30 000; the other in Zimbabwe aimed to supply yields greater than 0.2 l/s using hand pumps to small communities and villages from 100 to 2200 people. The higher yields in Nigeria are examined in relation to geology and aquifer characteristics, aquifer recharge, siting methods and borehole design. It is found that the higher yields are partly due to the c…
