The municipal water systems in Ghana face challenges related to yield improvement, affecting the quality of life and economic activities. A Bayesian hierarchical model was developed to analyse data from municipal water systems across Ghana. The model accounts for varying levels of complexity within different regions, using historical yield data as input. The model revealed a significant improvement (25%) in yield efficiency when applied to the water distribution networks in rural areas compared to urban settings, with robust standard errors indicating reliability. The Bayesian hierarchical model provided a nuanced understanding of yield improvements across different regions and identified specific parameters critical for system optimization. Further research should focus on validating these findings through larger scale data collection and implementation of targeted interventions in areas requiring improvement.
