Water Rationing Model for Consequence Minimization of Water Infrastructure Destruction Academic Article uri icon

abstract

  • This paper describes a model developed for optimizing water supply plans for water customers when a water network is partially operational due to the destruction of water networks by malicious attacks or any catastrophic events. The model uses the information regarding the priority of water customers in emergency situations, their functional sensitivities to water supply, and the dynamic nature of water demand patterns. The solutions generated from the model are water rationing plans which can guarantee at least a short-term water supply to water customers during any 24-h period. A genetic algorithm based program linked with a hydraulic solver (EPANET 2.0) is developed to find optimal water rationing plans. A case study indicates that the proposed model can successfully generate water rationing plans to reduce the consequences while meeting hydraulic constraints in water networks. The model developed in this study is also applicable to extreme water supply shortage situations due to severe drought or nonintentional incidents such as major pump failures and main breaks. © 2009 ASCE.
