Abstract

According to the importance of water loss accounting and non revenue water, providing loss reduction practice is important. However few studies have investigated a real case study from Iran in detail. In this research, a village in Northwestern Iran was selected as a case study. In the first step, the data by comprehensive surveying (1150 connections) and testing some users and village main water meters (based on Iran 556 code) are collected. Then the monthly consumption and apparent losses were calculated based on IWA standard. Then based on the data, the behavior of the water users are evaluated and their effect on the water loss is evaluated. Therefore by using the Borda count method for group decision making problem on eight alternative solutions, the replacement and calibration of the water meters is selected as a best way to reduce the non-revenue water and results communicated for the decision maker in water sector.
