The Emschergenossenschaft was founded in Bochum in 1899 and has been based in Essen since 1910. Its tasks include management of the Emscher, wastewater treatment and flood protection. Due to extensive mining in the area, underground conduits were not feasible as they would have been damaged in the event of subsidence caused by the mining. For this reason, the Emscher, as the main river in the region, and its tributaries were used as open waste waterways. Since mining activities moved northward at the end of the 1980s, subsidence caused by mining is no longer an issue, meaning that underground conduits can now be constructed. The Emschergenossenschaft has been planning and implementing the Emscher conversion since 1992. This major project is scheduled to be completed in 2020 and the Emschergenossenschaft will be investing a total of 4.5 billion euros over a period of 30 years.
The Emscher conversion brings with it considerable economic effects. This project will result, on average, in securing or creating approx. 1,400 jobs annually. This is the result of a study conducted by the economic research institute Rheinisch-Westfälischen Instituts für Wirtschaftsforschung (RWI). And, if one considers the indirect effects, this number will increase to an average of 3,700 newly created or secured jobs annually.
