| Abstract: | This paper points out the importance of adequate valving in providing water distribution system reliability and the problems in assessing the reliability of a water distribution system, using a link-node representation commonly found in pipe network models. The paper suggests using an approach involving ‘segments’ of a distribution system that can be isolated with valves as the basic unit for assessing reliability, and illustrates the use of a graphical approach to analyze the adequacy of valving. |
