This paper briefly describes six techniques developed for evaluating reliability of systems with complex configuration. Also, a brief comment about the computational aspects and applicability of each technique as applied to water distribution system reliability evaluation are made. Five techniques, except the connection matrix method, are applied to a simple looped water distribution system involving four demand points and eight pipe sections. It is found that all methods yield practically the same system reliability. However, from the computational viewpoint, the cut set method with a first-order approximation is the most efficient.
