Evaluating the seismic resilience (SR) of water distribution systems (WDSs) can support decision-making in optimizing design, enhancing reinforcement, retrofitting efforts, and accumulating resources for earthquake emergencies. Owing to complex geological environment, buried supply pipelines exhibit varying degrees corrosion, which worsens as age, leading a continuous degradation their mechanical performance, thereby impacting SR WDSs. Consequently, this study proposes an evaluation method WDSs that takes into account corrosive environment service age pipelines. Utilizing analytical fragility analysis method, research establishes curves various ages diameters diverse environments, combination with Monte Carlo simulation generate damage scenarios Furthermore, post-earthquake satisfaction is utilized characterize system performance (SP) Two repair strategies are employed damaged pipes: assigning single crew address damages sequentially deploying each location simultaneously, assess minimum maximum values The application results indicated decrease SP across 36 conditions was 32%, lowest value being 0.838. Under identical intensities, varied by much 16.2% different soil conditions. rare conditions, effect significantly outweighs impact on Post-disaster restoration minimize
