摘要：Water loss is defined as the volume o f water supplied to a system minus the volume o f permitted usage. Water losses contain real and apparent losses. Real loss occupies pipelines in the distribution network, junctions, fittings, and water tanks. Apparent loss is contained w ithin the metering devices, such as input, output and subscriber meters and, o f course, illegal uses. Apparent losses are also identified as managerial losses. The aim o f this study is to devise a strategy to prevent water losses in the Diyarbakir drinking water network by developing an efficient hydraulics method. To achieve this aim, in the four provinces in Diyarbakir (Sur, Baglar, Yenisehir and Kayapinar) parameters such as pipeline quantities, population, subscriber numbers and subscriber types are combined, to develop a new method for the selected regions using SCADA (Supervisory Control and Data Acquisition), SIS (Subscriber Information System) and Geographical Information System (GIS). In this study, Martyrs -1 (M -1) and Martyrs 2 (M -2) have been selected as pilot regions. To prevent water losses in Diyarbakir drinking water network some effective recommendations are suggested.
