Analysis of failures in water supply networks in the Samara region in relation to the material and service life of pipes

Summary

The statistical data analysis on failures in water supply networks in the Samara region for a specific period, based on pipe material, diameter, and service life is presented. The relationship between the failure rate and pipe material is determined, and the effect of the pipe service life on the probability of failures is studied. The data on the high degree of the Samara water supply network wear, broken down by the municipal districts, is presented. The failure rate for the network is calculated as the ratio of the number of failures to the length of the network. It is shown that sections of the water supply network with a long service life need priority repair or replacement to reduce failures.
