  4. Abstract:
  5. Due to increase of per capita water usage, water supply costs and population growth rate; optimal usages of available resources are vital. This is especially important in developing countries. If we add water resource deficits to the above problems, its importance duplicates. One of the ways of using resources optimally is utilizing transferred water in distribution systems properly and preventing its loss. Unaccounted for water (UFW) is an indicator of water loss in most cities. A big part of UFW is due to leakage of pipeline in distribution systems. Researchers have found direct relation between leakage and pressure in distribution systems. Earlier works have shown a series of laboratory results, which dose not represent the real situation in distribution systems, or the results have a high variety, in which no unique and accurate relation can be achieved. In this paper, water distribution system of the city of Sanandaj (capital of Kurdistan province of Iran) was selected as a case study. In order to obtain a mathematical relationship, a measurement including discharged water and pressure on five locations on the water supply pipeline was performed at the same time. To obtain a unique and accurate relation and to overlap probable errors, measurements were taken in 18 days in one-hour intervals. Results show a power trend line was fitted on the data and an experimental relation obtained with a low variety, which can be employed to evaluate the effect of pressure loss on leakage, and so to evaluate UFW
