摘要：Many phenomena are characterized by unevenness and
variability in time, so-called periodic fluctuations, of which seasonal
variations are a special case. In water supply systems, the failures of water
pipes are also characterized by unevenness during the year. Seasonality is
especially evident when the failures are analysed at particular times of the
year. The main purpose of this paper is to present the problems of failures
in water supply network caused by seasonal changes, to determine seasonal
indicators and to give an example of the system failure analysis for the
selected city of south-eastern Poland. The analysis was based on actual
operational data obtained from water supply company.
