ANALYSIS OF THE DAMAGEABILITY OF WATER AND SEWERNET WORKS
The main characteristics of water-carrying pipelines (for example, the Donetsk region) are considered. The factors that cause failures on pipelines are identified. The structure of the main types of damage to pipelines of various materials is given. The deterioration of the network and the accident rate of pipelines in the Donetsk region were analyzed. The negative impact of depressurization of pipelines on groundwater and surface water, atmosphere, lithosphere, social sphere and man is described. The dependences of the frequency of clogging of collectors on their diameter, accidents on the total length of the pipeline and the availability of mining digging, the number of pipeline failures on the time of year are given. A method of using failure criteria for «critical» points, a mathematical model for reserving and optimizing the operation of water-carrying communications are proposed. A system for monitoring and controlling the operation of networks, water quality and the choice of pipe material at reconstruction is proposed.
