Abstract. Energy saving technologies have recently been considered at the level of state and international policy. Various opinions on the causes of appreciation of energy resources, on depletion of natural resources, changes in climate and many other problems are coming from the expert community. Increasing tariffs and prices for the consumed energy and heat citizens can feel on themselves. The diverse opinions of representatives of all government levels, departments and organizations converge in one thing: it is necessary to reduce the energy consumption, develop energy efficiency and energy saving measures in the country which will contribute to this. The relevance of this study is based on the lack of a mechanism to meet the social, economic, aesthetic and ecological needs of a person. Nevertheless, the problems of ecology and environmental protection are still acute and urgent. Levels of water and air pollution remain high due to outdated equipment and insufficient integration of modern technologies and waste treatment facilities. Motor transport increased the pollution level of the urban airspaces. Taking into consideration the significant growth of passenger transport, the reduction of trucks in the general traffic flows does not reduce the overall air and noise pollution in the roadside territories.

When designing, constructing and operating sewage pipelines in high-rise buildings, issues of failure-free operation of a network arise. Investigation of the processes of wastewater moving allows identifying problem areas during operation, assessing the possibility of obstructions and breakdowns of plumbing traps on the gravity drainage sections of the pipeline. The article performs the schemes of the water outflow from the floor sewer into the riser, including the places where the riser is bent, of air delivery to the working riser under the change of the direction of drain movement with the dropout line set-up, with the installation of an automatic anti-vacuum valve, with the installation of the ventilation pipeline. Investigations of the process of sewage waste flow in a sewage riser were carried out, in order to select the appropriate structure. The authors consider structure features of some sections of sewerage in high-rise buildings. The exhaustion value in the riser is determined from the rarefactions that occur below the compressed cross-section of the riser and the loss of the air flow pressure coming from the atmosphere into the riser during the deflooding of the liquid. Preventing the formation of obstructions and breakdowns of plumbing traps is an integral part of sewage networks.
