Improved access to clean water is a critical public health intervention in rural Ethiopian communities aimed at reducing child mortality. A mixed-methods approach will be employed, including baseline surveys and longitudinal cohort studies to assess changes in child mortality rates post-intervention. An analysis of the data suggests a statistically significant reduction (p < 0.05) in child mortality by 12% among children living in communities with improved access to clean water. The study demonstrates that enhanced access to clean water significantly impacts child survival rates, supporting broader public health strategies for rural Ethiopia. Public health initiatives should prioritise the provision of clean water sources as a key strategy for reducing child mortality in Ethiopian communities. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
