Özet
Wastewater system failures cause operating conditions to deteriorate. Therefore, risk factors should be identified and rehabilitation priority should be established by considering all factors. Determining rehabilitation priority areas is very important in
terms of public health, service quality and operating cost. The aim of this study, which was carried out in Malatya, Turkey,
was to determine rehabilitation priority in wastewater systems by integrating the ENTROPY, ELECTRE and TOPSIS methods.
Some 26 physical, hydraulic, operating and cost factors were considered. The factor weightings were determined by the
ENTROPY method to define the factors’ contributions, based on the field data. Rehabilitation priorities were then determined
separately using ELECTRE and TOPSIS, taking the factor weights and field data into consideration. Priority regions in rehabilitation were obtained similar according to both methods. The results obtained will provide a reference for wastewater system
management and determination of rehabilitation priorities.
