Özet

Failures and leakages occurring in water distribution system increase operating costs and cause deterioration of operating conditions in urban water management. Various method for reduction, monitoring and control of the water losses are proposed and used in water loss management according to the current state of the system. Network rehabilitation and pipe material management can be shown as an important economic load for the Water Utility. For this reason, detailed analysis should be made and the worst regions should be determined before applying this method. In this study, it is aimed to determine the priority regions for rehabilitation in distribution systems in order to prevent water losses. Various factors that can be measured, applied and representing the problem were determined in the application area. Weight coefficients were calculated with the ENTROPY method to determine the degree of influence of these factors in decision making. ELCETRE I and PROMETHEE II methods, which are multiple criteria decision making methods, were applied in determining the priority regions in rehabilitation. Regions are listed based on the field measurements and weighting coefficients of the factors in the application area, and the regions with network rehabilitation priority are determined. Thus, it is possible to provide a solution that requires investment priority and aims to increase water resource and economic efficiency. It is thought that the results obtained in this study will serve as a reference in terms of network and water loss management.
