Due to the additional tunnels that are currently under design or construction, drainage maintenance costs are expected to rise significantly over the next few years. An increased amount of maintenance will also be necessary due to older drainage pipes damaged during intensive cleaning and flushing. To counter these problems, an internal task force for drainage pipes has been installed within the ÖBB. Together with research institutions from several fields of science, projects are being carried out to find ways to decrease the overall maintenance effort. Topics include screening of possible rehabilitation methods for damaged pipes, and investigation of currently used materials with regard to their mechanical suitability. A multi‐disciplinary research topic has also been initiated to investigate the potential of material modifications with the goal to decrease overall precipitation in drainage pipes and associated maintenance. First results on modified materials already show potential to decrease calcite precipitation.
