Abstract

The main objective of this study is to determine relatively weak pipes intersecting at nodes with relatively low reliabilities; it will help to point out the pipes to improve both for an existing water distribution network and a network in the design stage. The improvement can be realized by increasing the size of the concerning pipes and/or better valving of the related pipes; necessary reliability calculations were carried out based on the partially satisfied nodal demands that depend on pressure heads at the nodes of the water distribution network. A case study was conducted to demonstrate the algorithm.
