It is the world's most mysterious manuscript. A book, written by an unknown author, illustrated with pictures that are as bizarre as they are puzzling - and written in a language that even the best cryptographers have been unable to decode.

As all the world knows, Vienna is a city on the Danube.Day after day, the metropolis and its inhabitants consume roughly 370,000 cubic metres of water – hardly unusual for a city as big.It may come as a surprise that not one drop of this water is abstracted from the Danube.All water drunk, used for cooking, showering and flushing or drawn from wells, all water that enters sewers and treatment plants originates in the Alps.Crystal-clear drinking water adds glamour and brilliance to the city.How this valuable resource travels to Vienna, changing itself and the city in the process before ending up in the river, is the stuff of stories. This is the story of Vienna’s water.
