The reliability of municipal infrastructure assets systems in Tanzania is crucial for ensuring efficient urban services such as water supply and waste management. A randomized field trial was conducted in three municipalities, collecting data on asset condition, operational efficiency, and user feedback. Statistical models were used to assess reliability based on predefined KPIs. The analysis revealed a significant improvement in system reliability with an average increase of 25% in service delivery quality across the study sites, as measured by user satisfaction scores. This randomized field trial provides robust evidence for enhancing municipal infrastructure asset management and improving service delivery efficiency. Implementing standardised maintenance protocols and periodic audits is recommended to further improve system reliability and user satisfaction. municipal infrastructure, reliability assessment, randomized field trial, KPIs, urban services The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
