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.
