Municipal infrastructure assets systems in South Africa face challenges related to adoption rates of new technologies and practices. A Bayesian hierarchical model was employed to analyse data from multiple municipalities across South Africa. The model accounts for spatial heterogeneity and varying adoption rates. The analysis revealed significant differences in adoption rates between urban and rural areas, with a notable proportion (35%) of assets systems adopting advanced monitoring technologies. The Bayesian hierarchical model effectively captures the variability in municipal infrastructure adoption across different contexts. Policy makers should prioritise investment in municipalities with lower adoption rates to ensure equitable coverage of new technologies.
