Cost Effectiveness and Benefit Cost Analysis of Some Water Interventions in Bauchi State in Nigeria
A Cost-Effectiveness analysis of water interventions in Bauchi state, Nigeria, is presented in this report, with particular emphasis on pipeline and borehole (Hand pump) water supply schemes. Using the measures adapted from Whittington et al (2008), this study estimates the cost and effectiveness measures such as time savings and health benefit aimed at reducing the incidence of and death from, diarrhea disease. Firstly, it conducts a BASIC CEA which compares the cost per household per year of PWS with BWS program. Secondly, a PROGRAM CEA is performed to determine the relative effectiveness of the programs. The cost analysis shows that BWS is less expensive than PWS. Combining cost and effectiveness, the cost-effectiveness ratio shows the BWS is more cost-effective than the PWS program. Nevertheless, CEA is not sufficient to determine the most attractive intervention, since it cannot quantify cost and effectiveness in the same unit. Hence, a benefit-cost analysis, which estimates the monetary value of benefits, is applied. The results of the BCA seem to support the evidence that emerged from the cost-effectiveness analysis.
