Abstract

The water loss is the main problem at water distribution system. Water losses cannot be completely avoided, but they can be managed so that they remain within the economic limits. It is increasing of interests during last decade. The water losses percentage is relatively high in developing countries, as compared to developed countries, but both have the same problem. Water suppliers have not only a need to reduce and manage their losses, but they also have the methods and technology to do so effectively. Therefore, water losses in all water supply firms should be minimized as a target in the water distribution networks. Traditionally, several different performance indictors to compare water losses, percentage of system input volume or metered water ratio, and per km of mains per day, appear to be the most common, but these are reliable indicators for comparing performance. Nowadays, the international water losses indicators are using like: ILI, ELL, NRW (see Abbreviations), which are easy to compare among different countries. The actual economic and technical indicators of water losses in water distribution system should be analyzed. This paper aims to transfer and enrich the knowledge, about the technology and experiences in this field because of the lack of researches.
