Assessment of Current Implementation Levels of Apparent Loss Management Components with Current Status Evaluation System

zWater demand and difficulty in accessing clean water resources increase the importance of effective and sustainable management of water losses in utilities.Regular measurement of data, analysis of effective factors and efficiency of methods and tools are quite important for sustainable management of losses.The aim of this study is to develop a current status assessment system for analyzing the data quality and monitoring the current implementation levels of apparent loss management components.The system consists of 45 components under main headings of the technical, operation and maintenance, commercial and economic based on literature and field experience.A scoring system is proposed to evaluate these components between 0 and 5 (quite good, good, insufficient, poor and quite poor).The system is tested with using field data in three utilities.The data quality and current status of apparent loss management practices in utility II (generally good) is better than other utility I (insufficient) and III (poor).The components that need improvement within the scope of apparent loss management are defined in utilities based the scoring results.This system provides the opportunity to question in detail the quality, measurement frequency and accuracy of the data used in the apparent loss management in utilities.However, the main problem experienced in the implementation of this system is the lack of sufficient report, data and records for apparent loss prevention, reduction and detection methods in utilities.This assessment system will help more realistic data for apparent loss management in the utility and to allow the field implementations more accurately.Su talebi ve temiz su kaynaklarna eriim zorluu, kamu hizmetlerinde su kayplarnn etkili ve srdrlebilir ynetiminin nemini artrmaktadr.Verilerin dzenli lm, etkili faktrlerin analizi ve yntem ve aralarn verimlilii, kayplarn srdrlebilir ynetimi iin olduka nemlidir.Bu almann amac,
