Since 2004, promotional and educational activities have been organised on this day in all towns and municipalities along the Danube under the auspices of the International Commission for the Protection of the Danube River – ICPDR. The aim of these activities is to sensitise the inhabitants of the Danube region to the importance of the rivers and to promote their protection and sustainable use for future generations.

The Danube is the second longest (2,857 km) and one of the most water-rich rivers in Europe and the longest river in the European Union. The Danube rises in the Black Forest, a forested mountain region in south-west Germany, and flows eastwards, forming a delta on the shores of the Black Sea in Romania and Ukraine.

Today, as all of Europe is actively and diligently working to implement the European Green Deal, which aims to prevent water pollution at source, preserve water both qualitatively and quantitatively due to the strong impact of climate change, promote the application of digitalisation in relation to water monitoring and track losses in the water supply system to rationalise consumption, Danube Day is another opportunity for international dialogue on what each of us can do to preserve our water treasure.
