Training caretakers to clean community wells is a highly cost-effective way to reduce exposure to coliform bacteria

• Progress on improving access to safe drinking water is glacial, and existing strategies for improving access have met with only limited success. We consider an often neglected dimension of water infrastructure provision: cleaning. We randomly assigned caretakers of community wells to participate in a one-off training workshop about how to clean wells. Thirteen to seventeen months later, wells with caretakers assigned to receiving training have negligible rates of contamination with Escherichia coli and almost half the rates of contamination with any coliform bacteria, compared to control wells whose caretakers did not receive training. We estimate that the cost of preventing exposure to coliform bacteria in drinking water is US$0.88 per person and that if scaled up, each US$2034 spent on the intervention could avoid the death of a child. The results suggest that researchers and policy-makers who wish to increase access to safe drinking water should pay more attention to the unglamorous but important topic of cleaning.
