Viennese are (justifiably) proud of their drinking water; what comes out of their tap can go against most bottle water. Amazingly, it arrives via two separate gravity-fed pipelines. Pumping stations are not necessary as there is a gentle incline from the source all the way to south-west Vienna.
Water, Water Every Where… but not a drop to drink (because of E. Coli)
Vienna goes back to Roman times as the Danube was more or less the frontier between the civilized Roman World to the south and the unwashed masses to the north. Vienna was a glimmer in a Roman’s eye until they all high-tailed it south when the empire came crashing down about 4 AD. Over the next 1,600’ish years it went from an abandoned army encampment to a metropolis of nearly 2 million.
All cities are constrained by environmental factors including access to drinking water. Vienna is on two rivers, the large Danube and the smaller Wien. The problem is the former has already travelled nearly 1,000 km by the time it reaches the city and cannot be consumed straight. The other comes from the Vienna Woods but is not a reliable source of water because of its small watershed. As a result, wells were the primary source of water but were subject to contamination due to poor sewage handling.
The 19th century
The 1800’s was an engineering epoch and the problem of water was solved, in fits and starts, by engineers. The first water pipe was built at the start of that century but quickly was overwhelmed by a growing population. A water filtration system from the Danube was constructed in the 1830’s but was also overwhelmed. The first water pipeline was constructed in 1873 and serviced Vienna until 1910 when it was supplemented by a second line.
Of course the average home did not have a water tap, instead fountains and communal pumps were interspersed throughout the city and many of these still exist today. The water is still very drinkable but is now primarily a source for thirsty tourists and people without a tap in their home (typically due to a lack of a home).
Water Rights and Management
The City of Vienna owns the head waters of the two pipelines. As the water passes through Austria, communities the pipelines transit cannot access the water. A bit of the old imperial system that continues to today in which resources flow to the capital through the outlining areas.
Nevertheless, Vienna is a model of good water management and the importance of not only maintaining the local infrastructure but also the sources as well. An interesting thought as our world experiences climate change.
