Physical or real losses may be indicated as the most important component of the water losses occurring in a water distribution network (WDN). The objective of this study is to examine the effects of piping material management and network rehabilitation on the physical water losses and water losses management in a WDN. For this aim, the Denizli WDN consisting of very old pipes that have exhausted their economic life is selected as the study area. The fact that the current network is old results in the decrease of pressure strength, increase of failure intensity, and inefficient use of water resources thus leading to the application of the rehabilitation program. In Denizli, network renewal works have been carried out since the year 2009 under the rehabilitation program. It was determined that the failure rate at regions where network renewal constructions have been completed decreased down to zero level. Renewal of piping material enables the minimization of leakage losses as well as the failure rate. On the other hand, the system rehabilitation has the potential to amortize itself in a very short amount of time if the initial investment cost of network renewal is considered along with the operating costs of the old and new systems, as well as water loss costs. As a result, it can be stated that renewal of piping material in water distribution systems, enhancement of the physical properties of the system, provide significant contributions such as increase of water and energy efficiency and more effective use of resources.
物理损失或实际损失可能被认为是配水管网（WDN）中发生的水损失的最重要组成部分。本研究的目的是研究管道材料管理和管网修复对配水管网中物理水损失和水损失管理的影响。为此，选择由经济寿命已耗尽的非常旧的管道组成的代尼兹利配水管网作为研究区域。当前管网老旧这一事实导致压力强度下降、故障强度增加以及水资源利用效率低下，因此需要实施修复计划。在代尼兹利，自2009年以来一直在修复计划下开展管网更新工程。结果发现，管网更新建设已完成的区域的故障率降至零。管道材料的更新能够使泄漏损失以及故障率最小化。另一方面，如果将管网更新的初始投资成本与新旧系统的运营成本以及水损失成本一并考虑，系统修复有可能在很短的时间内实现自我摊销。因此，可以说配水系统中管道材料的更新、系统物理性能的提升，对提高水和能源效率以及更有效地利用资源等方面做出了重大贡献。
