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.
