Impact Evaluation of Accelerating Climate-Resilient Water, Sanitation and Hygiene Services for Schools and Healthcare Facilities in Karamoja

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 health and school attendance. It also examines adolescent girls' menstrual health self-efficacy. The study covers 60 primary schools that were found to be water-insecure across Karamoja's nine districts. The schools were stratified into three geographic zones. The researchers then used covariate-constrained randomisation to assign schools to three study arms. Phase 1 includes 30 schools receiving the intervention early. Phase 2 includes 20 schools receiving it later. The remaining 10 schools form the pure control group. The intervention combines climate-resilient WASH infrastructure with capacity-building and social and behaviour change activities. The infrastructure includes motorised boreholes, sex-disaggregated latrines and handwashing stations built to national standards. A subset of the boreholes will have data loggers for remote monitoring. The package also provides dedicated menstrual health facilities. These include enclosed changing areas and hygienic waste-disposal systems. Community water access points will be installed next to each school. Capacity-building activities will
