To assess the reliability of municipal infrastructure assets in Ghana using a difference-in-differences approach.
Applied a difference-in-differences model to determine reliability changes pre- and post-intervention.
Compared treatment and control groups to account for confounding variables.
Analyzed average system reliability scores statistically.
Observed a significant improvement in system reliability scores post-intervention (p < 0.05).
Confirmed the effectiveness of the DID model for measuring system reliability.
Suggested applicability of the methodology to other municipal contexts in Ghana.
