Evaluation of WHO’s contribution to water, sanitation, hygiene and health: Executive summary

The WHO WASH Strategy aims to improve health through the safe management of water, sanitation and hygiene services. To implement this strategy, WHO works through partnerships, notably with UNICEF, to promote equitable access to WASH services, support universal health coverage (UHC) and meet critical health and environmental goals, despite human and financial resource constraints.

The evaluation of WHO's contribution to Water, Sanitation, Hygiene (WASH) and Health had a dual purpose of accountability and learning, identifying good practices and opportunities for improvement. It assessed the effectiveness and added value of WHO’s WASH Strategy for health and its interventions. Its findings and recommendations will inform the development of the new WHO strategy.
