Failure frequency of water supply networks in the Podlaskie voivodeship

摘要

This article describes the subject matter of the failure frequency of water supply pipes in Poland. The introduction to the article describes the causes of failures in the water supply network as well as a tool for assessment of the failure frequency of water supply pipes, i.e. damage intensity index. The status of Polish literature concerning the problem of failure frequency of water supply networks is also presented, and attention is paid to the absence of studies within the area of the Podlaskie voivodeship. The research part of the article presents the results of calculations of failure frequency indexes for water supply networks in the Podlaskie voivodeship. Materials from the Central Statistical Office for the period of 2015–2017 served as the basis for studies. Damage intensity indexes throughout the entire Podlaskie voivodeship were analyzed. The status of failure frequency of water supply networks was assessed in poviats of the Podlaskie voivodeship during the years 2015–2017. The mean level of failure frequency of water supply networks was also compared between the Podlaskie voivodeship, other voviodeships and the national average. As a result of calculations that were carried out, reference material was obtained for current and future studies concerning failure frequency of water supply networks in the Podlaskie voivodeship as well as other voivodeships of northern Poland.
