Availability of the portable water in sufficient quantity and standard quality is one of the basic requirements of civilization. The study area of the present work is the University of Kashmir where the existing Water Distribution System(WDS) has served its function for more than 60 years. The UOK is a growing campus and the existing WDS is unable to meet the demands of a growing population and suffers from excessive leakage losses and insufficient pressure heads at the nodes. In this work, it has been attempted to replace the existing WDS with an optimally designed WDS for the University of Kashmir, so that the objective functions of maximum efficiency of performance in terms of hydraulics and minimum capital cost in terms of pipe diameters are met. From the literature available EPANET has been found to perform hydraulic and water quality modeling with a fair degree of accuracy, ease of use, and free of cost. Therefore, for the hydraulic analysis in the current work, EPANET 2.0 has been used. To augment the assessment of the efficiency of performance of the WDS, the TPI (technical performance indices) for pressure and velocity at the hour of peak demand have been evaluated. Finally, the cost optimality of the network in terms of the pipe diameters has been validated by using the JAL-TANTRA web system developed by IIT Bombay.
