Cash-based interventions are increasingly used in humanitarian response, including in the water, sanitation, and hygiene (WASH) sector. To strengthen evidence, we conducted a qualitative study on cash-based interventions programs for WASH operations and maintenance in Kachin, Myanmar. We collected field data for one programme and completed a desk review for two programs. We found camp-based committees were responsible for spending decisions and cash use was aligned with community needs/priorities. Programme strengths included community empowerment, time effectiveness; programme weaknesses included funding insecurity, limited training and monitoring and vulnerable groups inclusion. Recommendations for cash-based WASH operation and maintenance programs in Kachin and similar contexts are presented.
