Cost-effectiveness and benefit-cost analyses of some water interventions in Nigeria: the case of Bauchi State

This study presents a cost-effectiveness analysis and a benefit-cost analysis (BCA) of water interventions in Bauchi State, Nigeria, with particular emphasis on pipeline and borehole (hand pump) water supply programmes. The cost-effectiveness ratios show that the borehole water programme is more cost-effective than the pipeline water programme. The results of the BCA show that both programmes are beneficial, although borehole water supply has a higher benefit-cost ratio. On the whole, the results of the cost-effectiveness and benefit-cost analyses suggest that the borehole water scheme is more efficient and sustainable.
