The development of an example model to prevent physical losses in water distribution network in Diyarbakir city

Main factors that are threatening the potable water quantity are global climate change and increase in the world population. On the other hand, water is not distributed equally in location and time dimensions. Potable water amount is getting decreased deficient day by day. Increasing the potable water amount by natural ways is not possible and distributing equally among the nations as well. Desalination of the sea water is a synthetic solution, but it is an expensive way and not all of the countries can use it. Countries feeling the stress of insufficient water or drought are mostly undeveloped ones. On the other hand, water is becoming a commercial property, which makes impossible of equal distribution. The optimum solution is to improve the efficiency of existing water usage, controlling the existing sources, decreasing the water losses. One of the advantage of this solution is it can be applied to any country/city. Furthermore, it is cheaper and does not need expensive technologies. There are limited published studies on the subject therefore, such studies are still needed. In this study determination of water losses and illegal usage in an isolated water distribution network is examined in details. The study area is Diyarbakir city center. The infrastructure leakage index (ILI) at the end of the operations is decreased to 1, which initially were 44.
