Reliability and environmental safety of water and sewer pipelines

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 paper presents the reasons for the low reliability of pipelines. It is shown that the determining criterion for the environmental safety of pipelines is reliability - one of the main quality indicators of any structure (system). The research method was a statistical estimation of the reliability indicators of water supply and sewer pipelines, and an analysis of the factors that shape their change. The paper results in suggestions for a planning strategy of the rehabilitation and renovation of pipelines and reduction of all types of water losses.
