PRACTICE OF OPERATION OF WATER CARRYING TRANSPORT AND STRUCTURES OF WATER SUPPLY SYSTEMS IN THE ECOLOGICAL CONDITIONS OF MEGAPOLISES
The reasons for the destruction of pipelines are analyzed. An environmentally friendly and economically viable method for trenchless restoration of pipeline water supply and sewerage systems is proposed. The causes of destruction and possible defects of pipelines are considered. Biocorrosion is one of the causes of pipeline destruction. A method of pipelines restoration using a flexible polymer sleeve is described. Roughness coefficients for checking hydraulic calculations are proposed. It is concluded that ensuring the compatibility of water-carrying transport in the megalopolis should be based on the development of a unified strategy for the operation of water supply and sewerage systems with the existing infrastructure and man-made load on the environment.
