The renaturation of the Liesingbach is a project of the City of Vienna, which aims to redesign the river in a way that is close to nature and to improve flood protection. The Liesingbach flows 18.4 km through the city of Vienna and flows into the Danube Canal1 at Alberner Hafen. The first half of the Liesingbach was gradually renatured from 1997, the second half has been redesigned since 2020.
The renaturation of the Liesingbach is taking place in six parts, which should be completed by the end of 2027. The first component was completed in April 2021 and covers the section between Karl-Sarg-Gasse and Rudolf-Waisenhorn-Gasse in the 23rd district. The second part is scheduled to start in November 2022 and will cover the section between Großmarktstraße and Gutheil-Schoder-Gasse. The other components will be tackled in the following years.
The renaturation of the Liesingbach brings many advantages for people and nature. The bank areas will be flattened, planted and provided with stones and rootstocks to create habitats for animals and plants. The water quality will be improved by building an additional rainwater channel. Flood protection is increased by hydraulic engineering modifications being made to the retention basins. The residents benefit from more green space by the water, which invites you to walk, cycle or relax
