Multi-aspect Performance Analysis of Water Distribution Systems Under Pipe Failure

Performance analysis of a water distribution system (WDS) under pipe failure can be studied from different aspects. Performance analysis techniques are mostly restricted to the single performance index of supply ratio. This research applied novel technique of octant analysis to study the performance of a WDS in three aspects of adequacy, equity and efficiency of water delivery simultaneously. Results reveal that evaluating the performance of a WDS in just one aspect cannot guaranty the perfect overall performance of the WDS in future from all aspects. This study recommends octant/quadrant analysis as a more comprehensive tool for multi-aspect performance analysis of WDSs.
