With aging and deterioration of underground sewer utilities, there is an urgent need for a framework to track their reliability over expected lifetime facilitate asset management decisions like inspection, maintenance, or replacement. This study proposes multilevel, multifailure model evaluation reinforced concrete pipe (RCSP) considering the effect adverse environmental factors such as chloride sulfide induced attacks, uncertainties in different properties, seasonal temperature humidity variations, cracking effects. Monte-Carlo simulation with Latin hypercube sampling chosen stochastic analysis reduce computational burdens enhance accuracy. The application this illustrated case RCSP that has been service more than 35 years. Based on results, it shown at serviceability stage, wall erosion redundant relative other issues; therefore, cannot be used solely RCSP, previously done literature. At ultimate level, pitting corrosion dominates expedites failure rate. It proven huge potential reinforcement brittle under corrosion, which can lead catastrophic collapse.
