ABSTRACT

In deciding priorities for waterworks maintenance, a scientific and systematic approach would be needed to examine and analyze the main parameters affecting the leakage, along with water demand quantity, water pressure, energy costs, and so forth. In this study, a statistical analysis was performed to estimate the physical parameters in waterworks maintenance with the highest correlation with the leakage. For this purpose, water distribution analysis was performed to assess the demand energy ratio. The formula of non-revenue water estimation consists of independent variables related with physical parameters for waterworks. Deterioration rate of pipes, demand energy ratio and water supply quantity at each demand point were used in a multiple regression equation for water distribution network analysis. If regional characteristics of distribution network and demand patterns are considered in developed formula, the estimated accuracy for calculating the non-revenue water rate will be improved.
