Researchers have always been looking for better ways to develop the design, operation and implementationofwater distribution networks in GIS.Despite,extensivegeographical potentials of GIS,however, it cannot be independently considered as a spatial decision support system (SDSS) for management of this kind of networks. This research aimed to develop a spatial decision support systemin the form of standalone application for management of the water distribution network of FereidoonShahr City. This study attempts to combine advanced analytical hydraulic functions with the spatial analysis potentials of GIS software.In this regard, the identification and assessment stage was intended to develop the components of SDSS including Database Management component, Model Management component and Dialog Management component. By implementing conceptual, logical and physicalmodels in Database Management component, our geodatabase was developed. By using user friendly interfaces in order to communicate easily with users the Dialog Management component was developed. After that,in the Model Management component, some hydraulic models of water distribution networks such as velocity analysis model of pipes, and pressure on junctions were developed using ArcObjects components. Ultimately, alternative evaluating models were designed in order to solve semi-structured issues of urban water distribution networks. With the implementation of the above system for the first time in Iran which is based on a scientific approach, network administrators and analysts can use this software as a comprehensive SDSS in the analysis of urban water distribution networks.
