Specificity and methodological features of evaluating the reliability of sewer networks in large cities

Summary

The paper draws attention to the structural differences of two equivalent subsystems of a single infrastructure of a water supply and wastewater disposal system in a large city: a water supply subsystem and a wastewater disposal subsystem. It is stated that by now there is no unified established concept regarding the quantitative measure of the reliability of the sewer network. Based on the results of a review of modern domestic scientific and technical literature, three approaches to evaluating the reliability of municipal wastewater disposal systems are singled out and critically analyzed. The capabilities determined by the accepted assumptions are identified, and the areas of practical use of each of them are specified.
