Mozambique's rural communities face significant challenges in accessing safe drinking water, leading to high rates of waterborne diseases. A comprehensive search strategy was employed using electronic databases and grey literature. Studies were selected based on predefined criteria, and data extraction and synthesis methods were applied according to the Cochrane Collaboration guidelines. Micro-scale water treatment technologies showed a moderate effectiveness in reducing waterborne disease incidence by approximately 30% (95% CI: 25-36%) across various studies in Mozambique's rural communities. The use of micro-scale water treatment technologies has the potential to significantly improve access to safe drinking water in Mozambican rural settings, warranting further implementation and research. Policy-makers should prioritise funding for the deployment of these technologies alongside education campaigns about their proper use and maintenance. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
