| description | Recognizing, calculating and planning for reducing Non-Revenue Water (NRW) has been one of the aims and plans in Iranian water and wastewater companies for more than two decades. In the meantime, Real Losses (RL), which constitute a major part of non-revenue water, are mainly due to leakage in various parts of the water supply systems and a large part of the NRW reduction activities is put to prevent and reduce RL. However, like other projects and activities, it should be implemented to the extent with economic justification. Since it is difficult to achieve a quick and practical method for calculating the economic leakage rate, the companies often use a reduction in the percentage of non-revenue water in their targeting. However according to the IWA, the use of percentage of NRW as a technical indicator is never been recommended. In this paper, followed by a quick review of the performance indicators of non-revenue water, the method of benchmarking of non-revenue water, targeting actions, and calculating the economic leakage level (ELL) are presented for a city in Isfahan province. In this city, the real loss was 7 times the economic level of leakage. Therefore, the real loss reduction measures were proposed and planned among which the active leak detection in 10-month interval was the priority due to high ILI. |
