Abstract

At the present stage of reforming the housing and public services, toughening the requirements for the life and reliability of pipelines of the municipal life support systems, the issues of developing the requirements for choosing the material and type of pipes in relation to specific operating conditions of urban water supply systems become very relevant. The reliability and safety of the public water supply have been the main requirements applicable to these systems as the most important components of public health and one of the main priorities of the state social policy [1,2]. Of great importance in providing for the reliability of water pipelines is the expert choice of the pipe material. The paper states that for many years the main pipe materials used in the public water supply of Russian cities have been steel and cast iron. In recent years, ductile iron pipes widely used abroad and in Russia, in particular in the Moscow water supply system, have been competing with steel pipes (among metal ones). The paper presents the information on the condition of the water pipelines in the Russian cities, on the characteristics of ductile iron pipes and their use in soft and subsiding soils.
