Description

The dataset originates from an analysis of the long-term records of failures of a water distribution network (WDN) which provides the water supply in a town of about 30 000 inhabitants. The town is situated in Central Europe and covers approximately 24 km2. The failure records available covered the period from 2000 to 2016. The information available are not directly about WDN failures, but only about the repairs performed, accessible in the form of an aggregate record which included the number of repairs per calendar month. The dataset is based on the simplified assumption that the number of recorded repairs equals the number of failures which occurred during a given month. Information on the specific times at which individual failures occurred are not available. The numbers of failures recorded in this dataset are derived from the numbers of repairs performed. These repairs involved not only pipe breaks, but also all cases when the relevant WDN lost its ability to perform as required, e.g. pump failures and failures occurring when operating stop valves, water flow meters and other WDN parts.
