Hydraulic Models for Calculating Head Loss in Water Distribution System: a case study in Konya

The management of the water supply system becomes crucial day by because limited natural sources and rapidly increasing population all over world. However, distribution systems have various technical problems energy loss in can be counted one these problems. In this study, a designated area Yaka district Konya was examined using Hardy-Cross method and, hydraulic simulation softwares EPANET, WaterCAD which are used modeling frequently. same data were for EPANET study. calculations demonstrated that head calculated is 3.5% %16.2 lower than Hardy-Cross, repectively when PVC pipes network. When polyethelene network, 3.8% %26.6 repectively. case choosing as model system, project cost would increase slightly due to diameter reducing loss. It concluded comparing losses, more efficient Hardy-Cross.
