Vienna relies on water safety: mega-upgrade for pumping station Danube Island!

Donauinsel, Wien, Österreich - Vienna is on the way to make its infrastructure fit for the challenges of climate change. On March 19, 2025, the construction of Europe was presented to the most powerful rainwater pump on the Danube Island. With a capacity of 15,000 liters per second, this pump will significantly relieve the existing sewage system and is part of a comprehensive renovation project that also includes the energetic renovation of the pump plant. The investment of around 8 million euros was presented by climate city councilor Jürgen Czernohorszky and other political representatives and aims to cope with the contradictions of climate change, as often more heavy rain events. "Responsible politics now means thinking in the day after tomorrow," says Czernohorszky, who emphasizes the need to increase the drain capacity in order to improve security in the districts of Floridsdorf and Donaustadt, such as wien.gv.at reported.

The Viennese water supply is also characterized by the expansion. According to the climate city council, Czernohorszky, the city must act proactively in order to be able to provide sufficient fresh water in the future. A newly planned waterworks on the Danube Island is intended to help cover the average daily requirement by 22 percent. In addition, the existing storage volume in Neusiedl am Steinfeld is increased by over 60 percent, which enables up to 1 billion liters of water. These significant infrastructure projects cost around 100 million euros annually, such as Today. reported.

technological progress in flood protection

By expanding the digital infrastructure and the latest IT technologies, not only wastewater disposal, but also water storage and distribution is optimized. Using intelligent software, the Viennese sewer network is efficiently controlled in order to ensure the safety of citizens even in the event of impending heavy rain. In this way, the pumping system can vigorously dissipate water from the city in times of crisis by up to 80,000 liters per second. In combination with the new waterworks and the expansion of the Wien Valley Canal, which will create an additional storage volume of 60 million liters, Vienna shows how modern technology is used in wastewater management in order to meet the future challenges of climate change.
