BENCHMARKING OF WATER SUPPLY SYSTEMS - WATER LOSSES ASSESSMENT

Modern methods of benchmarking are starting to be use for objective evaluation of water supply level, these methods provide relative comparison of attained results of water companies. Possibilities for improvement of companies create by comparison of selected indicators, such way we can define situation of company considering other similar companies. Selection of figure of merits is the most important for benchmarking method to give desired results by comparison of them. Important indicators of evaluation of water supply are not only financial indicators, but technical too, technical indicators characterise technical condition of water pipelines, fault liability and with these related water losses. Water losses are significant factor, which affects inefficient exploitation of quality water sources. Management of water company needs to obtain information about selected indicators to can apply benchmarking methods. For that purpose benchmarking centres are starting to institute in the world. In this report will be presented new approach of evaluation of water losses indicators from point of view operator of water supply. There will be described benchmarking method which can be use for evaluation of water supply systems oriented for water losses. In this article will be presented results of evaluation of water supply systems in Slovakia.
