Abstract. The subject of the paper is the reliability and environmental safety of water supply and sewer pipelines of public water supply and sanitation systems. It is shown that the steadily increasing rate of deterioration of water supply and sewer networks in cities and communities in Russia, the limitations of material resources for their rehabilitation have aggravated the problem of ensuring their reliability in recent years. The reasons for the low reliability of pipelines are presented. It is noted that the determining criterion for the environmental safety of pipelines is reliability - one of the main quality indicators of any structure (system). A statistical assessment of the reliability indicators of water supply and drainage pipelines and an analysis of the factors that shape their change are performed. On the example of the Moscow water supply system, the empirical dependences of the failure rate of water pipes on their diameters, as well as the influence of the intensity and probability of blockages of ceramic pipes, are calculated. A strategy for planning the rehabilitation and renovation of pipelines and reducing all types of water losses is proposed.
Key words: pipeline, water supply, wastewater disposal, reliability, environmental safety, indicator, estimation. - REFERENCES
