This study proposes a framework to evaluate the water supply system reliability through life cycle assessment and system reliability theorems. Water supply systems in Taiwan mainly consist of three major subsystems: (1) raw water from reservoirs, (2) treatment plants, and (3) distribution networks. Reservoirs provide raw water, and water treatment plants convert raw water into drinking water that is later distributed to consumers through distribution networks. Reliability of water supply systems is composed of water quantity and quality. Mechanical failures occurring in the water treatment and distribution sections potentially lead to water supply system failures in terms of water quantity and quality; therefore, this study takes into account the mechanical failures that affect water supply system reliability. Life cycle assessment and system reliability theorems are employed to evaluate the water supply system. Shihmen Reservoir water supply system is hypothetically taken as a case study.
