Water and power systems are two national critical infrastructures which support our daily life and economic growth. Both are highly interconnected and complex networks, which consist of various system elements. The core functions of water and power distribution systems are to deliver satisfactory water and electric services to consumers by satisfying the demands at all load points. Besides the factors in the water distribution system itself, power supply may affect the performance of the water distribution system. Therefore, the two systems are in fact physically connected and coupled. The purpose of this study is to develop an appropriate model and an efficient evaluation algorithm to quantify the reliability of the water distribution and power supply system as an integrated Water-Energy Nexus (WEN). This paper proposes a probabilistic reliability evaluation method for the micro-WEN model based on the sequential Monte Carlo Simulation (MCS) procedure. In the proposed evaluation procedure, both mechanical failures and hydraulic analysis are taken into consideration. Case studies are performed based on a representative water-energy nexus system to demonstrate the effectiveness of the proposed method.
