Overview

Randomized trial evaluates stormwater infrastructure performance in Addis Ababa, suggesting maintenance and retrofitting needs.

Key Points

  • The aim was to evaluate stormwater infrastructure performance and prioritize maintenance and retrofitting in a micro watershed in Addis Ababa.
  • Assessed 30 stormwater infrastructure units across five urban blocks in a 30-hectare area.
  • Evaluated six performance criteria using field inspections and PCSWMM simulations.
  • Applied TOPSIS with AHP weights for ranking and conducted sensitivity analysis for robustness.
  • Block 3 scored highest in performance (Cᵢ = 0.7), while Block 4 scored lowest (Cᵢ = 0.43) due to structural issues.
  • 42.3% of the area is ready for green infrastructure retrofitting and 57.7% needs prioritized maintenance.
  • Spearman’s rank correlation coefficients exceeded 0.92, indicating strong ranking stability.
