The population growth and urbanization have gained importance in the Water Resource Management (WRM) works. The classic approach in relation to the development of the water resources has lost its sustainability. Water has, therefore, become an important, but also becoming a scarce natural source due to the global warming and its climate change impacts end results. The major aim of WRM is to increase the Water Distribution Network (WDN) to keep water supply sustenance by decreasing the water demand. The new approaches in relation to the WRM should take into consideration in a more refined manner the supply–demand balance with the improvements in the WDN. Recently, water resources performance improvements have become one of the significant investment topics in Turkey. However, data from the Turkish Statistical Institute and any academic research in this field have shown that there is a water loss of around 50% in the current water supply and distribution systems. In comparison to other developed countries, this loss is very high. It became, therefore, necessary that each Water Resources Administration should keep track on the costs, water leakage losses and the necessary technological investments. In the scope of this study, water loss levels reduction strategy possibilities are developed in the Sakarya City WDM system, Turkey. These strategies field applications have been presented in detail. Finally, the extent of accuracy in these strategies has been shown, which may provide guidance for other water administrations departments in the world.

人口增长和城市化在水资源管理（WRM）工作中变得越来越重要。与水资源开发有关的经典方法已经失去了可持续性。因此，由于全球变暖，水已成为重要的自然资源，但也成为稀缺的自然资源，其气候变化影响最终结果。WRM的主要目标是增加水分配网络（WDN），以通过减少水需求来维持水供应。有关WRM的新方法应更精细地考虑WDN的改进与供求平衡。最近，改善水资源绩效已成为土耳其重要的投资主题之一。然而，土耳其统计局的数据以及该领域的任何学术研究表明，当前的供水和分配系统中的水损失约为50％。与其他发达国家相比，这一损失非常高。因此，每个水资源管理局都必须跟踪成本，漏水损失和必要的技术投资。在这项研究的范围内，在土耳其的萨卡里亚市WDM系统中开发了减少水分流失水平的策略。这些策略的现场应用已详细介绍。最后，这些策略的准确性已显示出来，可以为世界其他水务部门提供指导。
