In the Vienna Lainzer Tunnel scale deposits were a substantial problem in a section of the underground water drainage system. The application of hydro-mechanical cleaning methods was no longer feasible and it would have been complicated to rebuild the drainage system. This section was thus treated with a 10 % hydrochloric acid solution between November 2012 and April 2014. In this way, it was possible to remove the scale deposits to such an extent that the drainage system could be purged by conventional means. These tests were accompanied by extensive monitoring, camera inspections and water analyses. It was proved that the application of hydrochloric acid had no harmful effects on the runoff ditch.
