Dispensers for Safe Water is a program run by Evidence Action that provides chlorine dispensers for decontamination of drinking water to reduce diarrhea and prevent associated deaths in young children.

Evaluation

A review by GiveWell found strong evidence for the effects of chlorination in reducing most diarrhea-causing microorganisms, but weaker evidence for a causal link between water chlorination programs and reductions in diarrhea and death among young children (GiveWell 2017). GiveWell estimates that the Dispensers for Safe Water program is in the same cost-effectiveness range as unconditional cash transfer programs (GiveWell 2017). Dispensers for Safe Water has been a GiveWell standout charity since 2017.
