New flood protection system for the Alpine Rhine

The River Rhine forms the border between Austria and Switzerland, stretching from its confluence with the Ill as far as Lake Constance. A major bilateral project, named ‘Rhesi’, aims to improve flood protection for the communities on both sides of the border, which have a combined population of about 300,000. Alongside this development, the river will also be ecologically enhanced.

This is a large-scale project, demanding coordination of policies and legislation between the Swiss canton of St. Gallen and the Austrian Federal State of Vorarlberg. Municipal authorities, drinking water associations as well as interest groups in both countries will work together on what is planned to be a 26 year project.
