Reliability Analysis of Water Distribution Systems

Based on node flow analysis the available nodal flows under deficient conditions is presented for determining the reliability of water distribution system (WDS). The reliability is concentration on a node-reliability factor. Volume reliability factor, and network-reliability factor. Even though reliability of WDS depends on several parameters, only variation of consumption in daily, demand excess, and element failure conditions are considered. Computer programs have been written to determine the aforementioned reliability factors. The procedure is described and illustrated through an example
