Pipe failure is a major parameter affecting the reliability of a water distribution network (WDN). A WDN consists of isolation valves which are closed to isolate a failed pipe for repairs. Depending up on the location of valves, a group of pipes termed as a segment gets isolated. Herein, reliability is estimated based on supply shortfall considering isolation of an appropriate segment on failure of a pipe. Supply shortfall is obtained using node flow analysis. An existing water main system is chosen as an example to compare the reliability values obtained by considering the actual location of valves and valves in each pipes on either end.
