What if I told you this seemingly ordinary tower saved lives? This is the Währinger Wasserturm. It stands as a testament to Vienna’s ingenuity in water management. Let’s step back in time to understand its vital role.
The Währinger Wasserturm is in the 18th district of Vienna. It is in Anton-Baumann-Park. You can find it on the Wiener Gürtel on the Ganslberg.
Following a severe cholera outbreak in 1830-1831, Vienna sought a better water supply. Emperor Ferdinand approved the Kaiser-Ferdinands-Wasserleitung project. Its purpose was to bring filtered Danube water to the city. Paul Sprenger designed the Währinger Wasserturm. Construction took place from 1836 to 1841.
The Kaiser-Ferdinands-Wasserleitung drew water from the Spittelau area. It fed elevated reservoirs in Währing, Neulerchenfeld, and auf der Schmelz. The Ganslberg reservoir was unique. It was the only one with an accompanying tower. The Währinger Wasserturm had a capacity of 141,250 liters.
Inside the Währinger Wasserturm were four standpipes. These pipes helped to equalize hydraulic shocks from the pumps. Unlike the Wasserturm Favoriten, it didn’t increase pressure. The tower may have served as a lookout point. From its top platform, people could enjoy views of the city.
A five-Zoll pipe ran from this water reservoir. It supplied water to several institutions. These included the mental asylum in the Narrenturm. Other places were the Old General Hospital, the Foundling Hospital in Alser Straße. It also supplied the Regional Court I. From there, water flowed to the Garrison Hospital I. Other locations supplied were the rifle factory. It also supplied the orphanage in Waisenhausgasse. Today the street is Boltzmanngasse.
The system soon became overloaded. In 1873, it was shut down. The I. Wiener Hochquellenwasserleitung replaced it. But during the winters of 1876/77 and 1877/78, it was briefly reactivated. It helped to alleviate supply shortages.
Without its original function, the Währinger Wasserturm fell into disrepair. By 1935, demolition seemed likely. Public protests saved it. The tower underwent restoration.
Today, the Währinger Wasserturm is in poor condition again. A renovation is planned from 2026. The U5 subway line extension will include an exit near the tower. Part of the ventilation system will be housed inside the Währinger Wasserturm.
The Währinger Wasserturm stands as a reminder. It is a reminder of Vienna’s efforts to provide clean water. It also showcases early 19th-century industrial architecture. Its story reflects both innovation and resilience.
