In recent decades, the limitation of urban water resourcesand the wear and tear of transmission lines, the short life span of water network elements, the increasing fracture of pipes and the high losses of networks have led to increased economic and social costs in the utilization of distribution network infrastructures. Lack of information, oldness of network data and the absence of spatial information system for incidents is one of the major problems facingmanagement of water transmission networks. Although the provision of such data is supervised by government agencies and is subject to certain standards, the problem of shortage, defect and delay is still evident. One of the solutions proposed to solve this problem is the use of citizen participation in the provision of spatial data. Using the Volunteered Geographic Information environments and the Information ofnative people can be a quicker and less costly method to update the maps. In the context of the present paper, Volunteered Geographic Information environment was used to accelerate the process of servicing in urban water network in cases of problems such as water pipes leakage, pipes rupture, illegal excavations, etc. After modeling and designing the proposed system, it was implemented in the Visual Studio2012 environment and in the ASP.NET framework using C# language.The SQL Server2012 database and GeoDataBase were used to store spatial and non-spatial information, respectively. ArcGIS Server10.2 software was used to enter the maps on the system. At the end, according to the survey resultsobtained from people, about 80 percent of participants in the inquiry were satisfied with the designed system. Also, based on a survey results obtained from four experts of water organization, three of them were satisfied with the design of such a system.
