Features of designing internal water supply systems unique high-rise and large-span buildings

Housing is one of the basic human needs, therefore, in all developed countries, one of the most important tasks of the state is to provide citizens with high-quality and affordable housing. At the same time, demographic changes, acceleration of urbanization, various transformations in scientific and tech-nological development form global challenges for the construction sector, in particular housing. One of the urgent tasks of our time is the growth of urban construction against the background of lack of available land. This situation has caused a significant increase in the construction of apartment buildings the versatility of these facilities requires a special approach to the design of engineering systems. The article considers issues affecting some specific aspects of the design of internal water supply systems of unique high-rise and large-span buildings. An analysis of the features of the choice of materials, technical solutions in the development of a project for cold and hot water supply of internal engineering systems, as well as equipment in the designated category of buildings, subject to increased hydraulic loads and specific regulatory requirements. A concrete example of a twenty-five-storey building located in the Sovetsky district of Astrakhan, which includes premises for various purposes (residential, commercial, sports, etc.), can illustrate how, in the context of unique architectural solutions and technical challenges associated with large spans and height of the structure, such important aspects as safety, environmental friendliness and energy efficiency of these systems are realized
