Using and Abusing a Torrential Urban River: the Wien River Before and During Industrialization

The Wien River is the largest tributary of the Viennese Danube and was a center of urban production during industrialization. It’s highly dynamic flow regime with small average discharge as well as recurrent big, fast floods posed challenges to its use. In this study we focus on the role of this urban watercourse for supplying water to crafts and industries and for wastewater discharge in the 19th century. Animal slaughtering, tanning, dyeing, textile printing, beer brewing, and chemical industry as main water demanding and polluting crafts were investigated. Their location in the catchment was determined and they were systematized by their needs of water and types of pollutants released into the river. Spatial distribution patterns of these industries from the end of the 18th to the end of the 19th century show a complex picture in terms of water supply and waste water discharge. We found very distinct patterns for different sections of the river as well as for different crafts and could observe a change over the time period investigated. Only few types of businesses lied close to the Wien River which can, to some extent, be explained with the high risk of flooding. Groundwater played a more important role for water supply while the main function of the river was wastewater discharge. Spatial distribution of crafts and industries, and changes in locations resulted from an interplay of environmental and social factors. Availability of surface waters, water supply, and discharge infrastructure (wells, pipelines, sewers) seem to have been important for the choice of location for production sites. Regulations concerning the exertion of industries, economic factors and technological innovation also played a role in the development of the observed spatial pattern.
