Problems of the reliability of water supply and wastewater disposal systems, and ways of solution

Summary

Reliability and environmental safety are the main requirements for water supply and wastewater disposal systems. Pipeline systems are an integral part of the infrastructure of modern cities. Malfunctions of these systems are mainly associated with failures in pipeline sections, that are the most functionally significant, expensive and vulnerable elements of the systems. The increasing rates of wear and unsatisfactory technical condition of a significant number of water pipelines and sewers in most cities and communities of Russia, the limited material resources for their rehabilitation and renovation in the context of reforming the housing services and public utilities of Russia require a scientifically based approach to solving the problem of assessing and ensuring their reliability. It is noted that up to now, in domestic practice, the accumulation and use of statistics for determining the reliability indicators of the elements of water supply and wastewater disposal systems, as well as planning their rehabilitation, have been arranged unsatisfactorily. Methods for assessing the reliability of pipelines, a methodology for planning their rehabilitation using a software application, criteria for selecting objects for pipeline renovation and ways to improve their reliability are presented.
