Özet

The well known hydraulic and water quality network simulation model, EPANET, is applied to the drinking water distribution network of Baris District in Antalya City, Turkey. Nine measurement and sampling stations were chosen to represent the study area. The water pressure at the pumping station was recorded during the field measurements while two different sets of water samples were analyzed in the field for chlorine residual at all the stations. Additional water samples were collected at some stations and analyzed for many physical, chemical and biological water quality parameters. Moreover, the bottle chlorine bulk decay coefficient was determined in the lab as 4.3434 day(-1). The two different field measurement sets are used to calibrate and verify the model. The calibration process resulted in a wall reaction coefficient equal to 0.025 m day(-1). In addition to predicting the chlorine residual levels along the network, the model also predicts many hydraulic characteristics such as pressure, velocity and flow rates in the network.
