| Abstract | How does the Viennese water supply work? View the facilities and the fundamentals of the physical region: from the urban area storages to the catchment area springs in the Styria, taking account of scientific research projects in the context of karst research (geology, hydrology, karst hydrology, biology/vegetation, forest ecology, snow measurement programs) |
| Learning objective | The participants of the excursion learn: 1. How the Viennese water supply works. 2. Which constructions and facilities are required to operate such a large water supply, especially in the case of the Viennese spring water supply (1st and 2nd Viennese spring water main) - reservoir "Rosenhügel" (in the city area) - the biggest closed reservoir of Europe "Neusiedl am Steinfeld" along the 1st Viennese spring water main (out of city) - 1st and 2nd Viennese spring water main with a length of up to 200 km (gravity pipelines) - tapping of springs - crop-out of the biggest tapped karstic spring in Central Europe - protected areas in the natural environment 3. Which measures are taken by the city in the protected areas: - demarcation of the protected areas (conflict of land use vs. clean drinking water) - possible causes of risk and risk management - optimization of spring water management, especially in terms of water quality - measures in the case of spring water pollution 4. How the quality of the potable water is monitored at the spring sites (online measurements). 5. Which measures are taken in the case of a drinking water shortage at the springs during a dry period. 6. Which scientific projects does the Vienna Water Works pursue with respect to climate change and future scenarios for drinking water supply. |
| Content | - Visit the two waterworks museums in Kaiserbrunn and Wildalpen for discovering the historical process of water supply in the city of Vienna - Tour of the premises and the vertical deep wells in a glacial aquifer that serve partly for drinking water supply for the city of Graz. - Various aspects of Karst systems and the relevance of branches of science such as Karst hydrology, geology, vegetation and soil science. |
