Practical methods to obtain improved outputs from Water Network Modelling Optimization

Abstract

Methods are discussed to improve detection of unknown closed valves and location of leakage hotspots within water mains network modelling optimization analyses. Pressure and flow trending data has been modified, considering likely flow patterns, to include hydrant discharges. Pressure drop amplification by planned valve closures and the benefits of additional hydrant flow data capture has been explored. Water quality risks have been mitigated by application of discoloured water theory developed since 2005.The interdependence of modelling with past leakage reduction and water quality strategies is reviewed and the paper helps support case for wider use of water mains network modelling optimizations. © 2013 The Authors.
