Özet

Leaks occurring in distribution systems constitute a significant part of water losses. Active

leak control methods (DMA, MNF analysis, repair speed and quality) are applied to manage

and control the leaks. It is very important to use appropriate indicators to determine and monitor

the performance in the process, and compare the systems with each other. In this study, it

was aimed to use the infrastructure leakage index (ILI) proposed by IWA and considered as

the unique indicator that is used to compare systems with each other in order to analyze and

monitor system performance in leakage management for pilot regions. However, the use of this

indicator, which is preferred by a limited number of Utilities in Turkey due to the lack of information

and awareness, and lack of technical infrastructure, requires basic data representing

the system characteristics. Based on the pilot case studies, the role and advantage of this indicator

in leakage management, the problems experienced and the interpretation of the results

were discussed. With this indicator, it is possible to determine the leakage level in the current

conditions and to determine the most suitable process accordingly. It is thought that this study

will make a significant contribution to technical personnel in terms of leakage management.
