Water shortage is one of the most important challenges of this century and it would be a serious obstacle for the mankind.In the near future, drinking water supply and water resources management will be at the forefront of planning for urbanmanagers, which is becoming a crisis due to the serious shortage of water resources. This problem is more critical incountry of Iran, where water depletion is now receiving serious attention. Different water management programs have beenstarted by government to conserve and manage water more efficiently, especially in some critical areas such as Tabrizmegacity located in North East of the country. Eram town is one of the problematic areas of Tabriz. Hence, in this study,we tried to do reengineering for this town to offer some solutions for the problems related with water supplying of theimplemented network in this region. Regarding this issue, the GIS (Geographic information system) data of the availablewater supply network was used and the collected field data such as consumption rates in current conditions were appliedto the network. Then the calibration of model was performed. Eram Town water distribution network reengineering hasbeen performed considering a 2043 plan, taking into account population growth and the increase in consumption. Inconclusion, it is suggested that, the network will perform more efficiently by adding new pipes or modifying the existingpipes. Also, the problem of lack of pressure in some parts of the network which cannot fulfill the requirements ofsubscribers at peak water usage hours, could be solved.
