The fight against leaks and failures in water distribution systems has gained a serious importance with the increasing drought, the inefficient use of water resources and the rapid contamination of existing water resources. These studies are generally carried out with two different approaches, active leakage control and passive leakage control. Although the passive control method, which covers the repair of the reported faults, is less costly and easier, the vast majority of the faults that occur in the system are caused by unreported faults. It is possible to detect, repair and control such faults with active leakage methods. In order to gain the expected efficiency from these methods, it is very important to regularly monitor the networks by dividing them into isolated areas, to estimate the amount of preventable leakage, and to determine the leak location with devices and equipment such as ground microphone, regional recorder, regional correlator within the framework of a certain systematic program. The regular maintenance of these systematic studies in the implementation of the active leakage method also creates serious costs for water administrations. In addition to the costs of creating and monitoring measurable regions, the costs of devices and equipment with different characteristics, sensitivities and costs to be used for the determination of the fault location should also be considered in the studies to be carried out. In this study, a standard calculation structure is defined for the benefits and costs of the ground microphone and regional correlator methods used to locate unreported leaks. By using the defined calculation methodology, the benefits and costs for both methods are analyzed and compared in a sample network. The method to be selected according to the general characteristics of the networks plays an important role for the most efficient operation.
