| Abstract | Recent studies have shown that improved public water supply does not necessarily improve water quality at point-of-use and/or health outcomes. In this study we provide a detailed analysis of this phenomenon, applying a quasi-experimental difference-indifference analysis in combination with a randomized control trial to 200 villages and 1989 households. We find that households consider improved water supply and water handling as substitutes of water provision, whereas in reality they are complementary. Improved public water infrastructure improves water quality at the water source. However, there is no impact on the quality of the water consumed and/or on health outcomes. We show that an increase in the perceived water quality of households reduces the (already low) propensity of households to engage in water filtration and disinfection practices after the provision of modern water technologies. Only a combination of water point provision and water handling methods leads to a decrease in E. coli (-89 percent) contamination of water consumed in households and diarrheal incidence (-20 percent) in children. |
