Benefits and Costs of Drinking Water, Sanitation, and Hygiene (WASH) Interventions evaluates the economic and social impacts of improving access to safe water, sanitation, and hygiene services. The analysis quantifies both the costs of implementing infrastructure, operation, and maintenance, and the wide-ranging benefits to society.
Key benefits include reduced incidence of waterborne diseases, lower healthcare expenditures, increased productivity, time savings from easier water access, and improved educational outcomes, particularly for children. The study also considers environmental and community-level advantages, such as reduced contamination and improved public health.
Cost-benefit analysis demonstrates that WASH interventions often generate high net social returns, with benefits exceeding costs by several times, making them highly cost-effective. Overall, the findings support prioritizing WASH programs to achieve sustainable health, economic, and social improvements in communities worldwide.
