Ways to improve operational reliability of water supply and wastewater disposal ­systems in buildings

Abstract

Ensuring operational reliability of engineering systems of buildings, regardless of their functionality, is one of the most important problems of the state, regions, municipalities and specialized business. At the same time, operational reliability is not only a technical and technological category, but also an economic and social one, because the increase in the terms of safe and reliable operation, reduction of repair costs are equivalent to the effects that can be obtained only from the construction of new buildings. This implies the need for a targeted study of the operational reliability of engineering systems by solving a number of applied problems.

The global picture of drinking water losses and environmental pollution from wastewater is very sad. The figures are measured in billions of cubic meters per year. In Russia, with its difficult climate, and where a significant part of the engineering infrastructure of buildings is worn out, and new buildings are often delivered with corresponding deficiencies, this problem is particularly acute. Despite numerous discussions of theoretical provisions, analysis and systematization of experimental data in available publications, these issues remain on the periphery of scientific interests of specialists, and the indicators of operational reliability have not been fully investigated. In this article the key aspects and modern solutions of the way of formation and increase of operational reliability of water supply and drainage systems (hereinafter referred to as WSS) of buildings are considered. The authors analyzed the normative and technical regulation of these issues, the existing methods of determining reliability and ways to improve it, the prospects and projected effects of new technologies on this path, the challenges and opportunities of transition to predictive maintenance.
