Effective Factors in Causing Leakage in Water Supply Systems and Urban Water Distribution Networks

Abstract

Water has a vital role in the country‘s economic development, since most part of it is dry and desert. Whereas, water has been cheap and easy accessing, the authorities of the urban water distribution organizations have not paid so much attention to the decreasing of the unaccounted for water (U.F.W) as a solution for saving water, the decreasing of the cost of preparing water and the increasing of their efficiency or income. In recent years, the U.F.W has been paid attention because of the shortage of resources and the cost increasing of water preparation. Therefore, along with preparing water from new resources, the water wasting in different stages of transmission, refinement and distribution of water should be prevented as a long term programing. In this article, the effective elements in causing leak have been explained. The results show that the most leakage of water deals with the parameters such as pressure, quality, diameter and age of the pipes.
