STATE WATER SUPPLY NETWORKS UKRAINE TERMS OF RELIABILITY
Abstract
Water network is a major and important elements of the water supply system requires special attention on high reliability pipelines. The paper analyzed the statistics of failures pipelines for the five cities of Ukraine, namely, Poltava city, Kremenchuk city, Lutsk city, Karlivka city and Lubny city. On the basis of the statistical data classified the causes of failures and diagrams causes damage to the water pipes; calculated numerical value of the specific failure flow parameter set analytical failure flow parameter depending on the diameter of metal water pipes and built curves. The calculated weighted average value failure flow regardless of the diameter of the Water researched cities of Ukraine.Keywords: water supply system, water networks, metal pipe, indicators reliability, reliability, maintainability.
