With the emphasis in recent years on intentional andnonintentional contamination events and optimal sensorplacement, water utility managers are interested in networkskeletonization issues because some degree of networksimplification or aggregation is required to obtainboth hydraulic and water quality results and assessmentestimates within reasonable time frames and restrictivebudgets. A method has been developed that can simplifycomplex water distribution system network modeling sothat the reduced or simplified network provides reliableresults for both pressures and contaminant concentrations.The methodology for network skeletonization presentedhere is based on both hydraulic and water qualityaggregation of an all-pipes network. In thisresearch, the aggregation method was capable of reducingsystem size by almost half, while still preservingsystem characteristics in terms of reliably simulatingpressures and concentrations.These results demonstrated that even when anaggregated representation of an all-pipes network isused, reliable hydraulic and water quality resultscan be obtained. Utility managers using a reducednetwork that is based on the methodology describedin the article can be confident that the reliabilityand robustness of simulated results have not beencompromised.
