What the trial is, and whether it could suit you
Karamoja, in north-eastern Uganda, is among the most water-insecure regions in sub-Saharan Africa. Only 24 per cent of households can access the WHO-recommended 20 litres of water per person per day. Only 11.7 per cent have access to improved sanitation. A rapid vulnerability assessment covered all 182 operational primary schools in the sub-region between October and November 2025. It identified 53 schools as severely water insecure and a further 37 as moderately water insecure. Together, these schools serve an estimated 196,000 learners. The assessment also found that 89 schools lacked enough latrines to meet the national pupil-to-latrine ratio. Seventy-eight schools had no functional menstrual health management facilities.
This study is a three-arm, phase-in cluster-randomised controlled trial. It evaluates the causal effects of a climate-resilient school WASH package on children's he
