DSW is a project of Evidence Action, whose mission is "to be a world leader in scaling evidence-based and cost-effective programs to reduce the burden of poverty."
- DSW provides chlorine dispensers to low-income communities, where drinking water is often contaminated.
- According to the World Health Organization, treating water with diluted chlorine is a safe and effective way to improve water quality.
- DSW estimates that they have distributed more than 27 thousand dispensers in rural Africa, reached 4 million people, and prevented more than 380 thousand cases of childhood diarrhea.
- They estimate that it costs less than $1.50 to provide safe water for one person, for one year.
- To ensure that the dispensers are used, DSW engages with communities and each community appoints a "promoter" for the dispensers.
- Evidence Action's DSW project is based on evidence, and they provide a detailed review of that evidence on their website.
- DSW is a GiveWell standout charity. GiveWell believes that DSW is roughly as cost effective as unconditional cash transfers.
- In 2019, DSW received a grant of $100,000 from Open Philanthropy. We consider this grant a vote of confidence from an organisation we trust.
- Evidence Action told GiveWell that it could use up to $4.7 million per year to support its current operations, or more to expand its operations.
