Water resources management is one of the most important issues that are considered by experts in this field due to the reduction of rainfall and the reduction of groundwater levels. In this study, to reduce pipe fractures and water loss in Salehabad city (Comparison of water production and customer consumption data showed that there is more than 60 percent water loss in this network) field studies, pressure gauges, leak detection, and hydraulic analysis were performed by combining AutoCAD, WaterGEMS and GIS software. Points of the water distribution network that had more than 50 mH2o pressure were identified and then by field studies and using the method of closing the gate valves as a step by step, 6 points were identified as high-risk points of leakage. Therefore, with the check of the areas by the leak detector, 3 cases of pipe fractures were found and the remeasurement showed that the repair of these pipe fractures had reduced water loss by 20 percent. Depending on the urban texture and topography of the area, it was suggested to reduce the network pressure to 16 to 30 mH2o by installing a pressure relief valve in critical points of the network.
