Water losses occurring in distribution systems have effect on the operating cost, water and
energy efficiency, service quality, customer satisfaction, maintenance and new resource demand.
The standard water balance recommended by IWA were used for defining, analyzing,
regularly monitoring the water balance and sub-components, and determining the weakness
and strengths of system. Water Utilities in Turkey are required to fill the water balance annually
in order to analyze and monitor the performance with the regulation published in year
2014. However, in the use of this table, important problems are experienced due to the lack of
technical, technological, personnel and economic conditions, data representing the field are not
used and in many cases the real performance of the system is not revealed. In this study, the importance
of IWA water balance in water loss management and monitoring system performance
is emphasized, and the benefits and advantages are detailed by analyzing the pilot regions. In
addition, problems encountered during filling the water balance, mistakes made, incomplete
or incorrectly filled data and other problems were discussed. It is thought that this study will
constitute a reference for the technical personnel in Utilities for measuring the data, analyzing
the components and interpreting the results.
