Purpose and Objectives The purpose of this study is to evaluate the effectiveness of current municipal water systems in Nigeria using panel data analysis, with the objective of identifying strategies for enhancing water supply yields. Methodology Panel data estimation techniques will be employed to analyse the impact of various factors on water yield. This approach allows for the examination of temporal and spatial variations within the Nigerian context. Findings A preliminary analysis suggests that investment in infrastructure upgrades can lead to a 2% increase in water yield, with significant variability across different regions of Nigeria. Conclusion The study concludes that while there is potential for improvement, targeted investments and policy adjustments are necessary to
