Ortaköy Muğla su dağıtım şebekesinin EPANET ile hidrolik modellenmesi

Getting good quality water is a right of every person, that water must be delivered to needed places with good pressure and velocity. A water distribution system (WDS) is used to supply water through pipes, which carry the water from the source to consumers. Usually water is pumped from the source to either an elevated storage tank or directly for consumption. Because of its vital importance, WDS is modelled for many reason including solving an existing water supply problems or forecasting the function of a WDS before any pipe is laid. In this study a hydraulic model is developed for Ortaköy which is a neighborhood in Menteşe city in Turkey. To develop this model, EPANET is used. It is a free software used for designing water distribution systems that uses a demand-driven approach and solves for the hydraulics equations using the Gradient algorithm. A magnified demand is used as an input to check whether the WDS could work under extreme demands and an extended period simulation (EPS) was run for three days. Muğla local water authority provided the data that is to be used in the study. Designing will be made while considering the existing hydraulic model of the city. The hydraulic model will be checked for possible problems including negative pressure and the problems of the old design will have to be fixed with rehabilitative suggestions. Those will be in the form of alternatives that solve problems with different methods. The simulated result will be compared with recommended pressure and velocity requirements in the neighborhood.
