Review on the development of uniform failure registration (USTORE) in the Netherlands

“Deciding which pipeline to replace when is one of the main issues for asset management of the drinking water distribution network. Drinking water companies use decision support software tools (DSS) in their planning for pipe replacement. This DSS requires information about the risk of failure, i.e. the probability of pipe failure and the effect or impact of pipe failure. In 2008 the Dutch drinking water companies together with KWR launched the initiative USTORE for acquisition of uniform and consistent data about pipe deterioration. In USTORE data of pipes and pipe failures are uniformly registered. USTORE data is used in data analyses to gain knowledge about deterioration of pipe cohorts and to increase understanding of external effects which may cause pipe failure. Currently the USTORE database contains data of around 20.000 failures and 60.000 km of pipes. This paper evaluates the development of USTORE registration and reviews data analysis results, data quality issues and applications of USTORE failure data.”
