PRESSURE-LEAKAGE RELATION IN URBAN WATER DISTRIBUTION SYSTEMS

The water distribution system of Sanadaj, capital of Kurdistan province of Iran, was selected as the case study of this case study. The study's aim was to formulate the relation between pressure and leakage in the chosen water distribution network. The tests contained a set of simultaneous discharge and pressure measurements on a pipeline at specific locations; the data were evaluated and analyzed after the measurements. In order to increase the test accuracy, the selected pipe was very old cast iron and had a high leakage. The results indicate a power trend line on the data, and a low variety on the experimental relation which can be employed to evaluate the effect of pressure loss on leakage which can be used to evaluate the amount of the unaccounted for water.
