Development of a data filtration method for strategic data acquisition in sewer rehabilitation planning

摘要

Many of the current tools for sewer rehabilitation planning are too complex to be applied in practice, and in Austria for example, no standardised approach regarding sewer rehabilitation planning is currently available, making comparison between utilities difficult. In a three-year research co-operation between universities and sewer operators, suggestions for standardising performance requirements for sewer rehabilitation are being compiled, as well as a supporting data filtration method. In this paper, Florian Kretschmer, Hanns Plihal, Daniela Fuchs-Hanusch, Michael Moederl and Thomas Ertl describe the basic idea of the data filtration method, as well as the first results obtained regarding the definition of different performance indicators.
