Abstract
Solar-powered water treatment systems (SWTS) have been implemented in several rural Ugandan communities to improve access to safe drinking water. A comprehensive search was conducted using electronic databases and grey literature. Studies were selected based on predefined criteria and analysed using a random-effects model with robust standard errors. Six-month follow-up data indicated that SWTS significantly increased safe drinking water access by 35% (95% CI: 20-48%) compared to baseline conditions, highlighting the need for continued support and maintenance. The meta-analysis supports the efficacy of solar-powered water treatment systems in improving rural Ugandan communities' access to safe drinking water six months post-deployment. Further studies should investigate long-term sustainability and cost-effectiveness of these systems, with a focus on community engagement for optimal performance and user acceptance. Treatment effect was estimated with $\text{logit}(p<em>i)=\beta</em>0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
