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.

The use of a hydraulic electronic model to assess the functioning of the water supply network

“…-After the hydraulic calculation has been performed by the macro calibration algorithm, the value of the E function is calculated using the formula (1). Based on the values got, a surface is formed that reflects the dependence of the target function E on the maximum roughness values of pipelines made of different materials.…”
