SHARING FAILURE DATA TO GAIN INSIGHT IN NETWORK DETERIORATION

摘要

Maintenance and failure records can be used to obtain information about the condition of underground infrastructures. Failures, although in itself unwanted events, offer a great opportunity to obtain network information, provided that they are registered, collected and analyzed. The Dutch water companies generally have low failure frequencies. By sharing failure data between water companies, information about a larger network can be obtained, thereby sooner enabling statistical analysis with reliable outcomes. In order to perform statistical analysis on different data sets, the data have to be uniform. In The Netherlands a system is developed to enable uniform failure registration and exchange of information between water companies. This paper describes the experience with the development of this system that aims at application on a national scale and delineates the hindrances met at the implementation on company level and how these are overcome.
