It is sometimes argued that rural water supply boreholes are simple and don’t require much technical input. This is an erroneous view – boreholes which are poorly designed, sited and constructed may have yields that are inadequate, marginal or unsustainable, and short lifetimes. They may also supply water of poor quality for drinking and domestic use. A lot of programme funds may be wasted. Even where the designs are appropriate to the local groundwater conditions, lack of supervision of construction often compromises the quality of the final product. In a large programme, the resulting cumulative loss of investment may be the same as the investment for a few properly specified, high-yielding urban boreholes. Nobody would question the need for proper technical inputs for both design and supervision in the urban context.
