Municipal water systems in Tanzania face significant challenges related to cost-effectiveness due to limited data on system performance and financial outcomes. A mixed-method approach combining econometric techniques such as fixed effects models to analyse panel data from multiple years. Robust standard errors are used to account for potential omitted variable bias. The analysis revealed that water system investments in urban areas have a positive but modest impact on reducing water-related costs, with an estimated cost-effectiveness ratio of 10: 1. This study provides insights into the financial sustainability of municipal water systems and highlights the necessity for targeted interventions to improve efficiency. Policy makers should prioritise investments in infrastructure maintenance and staff training to enhance system performance and reduce costs.
