As part of the Emscher Conversion generation project, the Emschergenossenschaft redesigned also the Katernberger Bach stream, which, for the most of part, has been flowing through the Katernberg district of Essen since the 1960s. Along a stretch of 1,100 metres, the stream was given new space next to the old watercourse route and is now running open along 1.2 kilometres. The opening of the stream and the separation of clean and wastewater as well as the renaturation of obstructed drainage profiles enable an ecological improvement of the watercourse. In addition to the river engineering plans, bed slides, fords and a bridge as well as several culvert structures have been implemented. Accompanying measures along the ecologically revitalized watercourse enhance the green corridor and create a high recreational quality for the Katernberg district. The Emschergenossenschaft commissioned DAHLEM with the project planning, structural design, technical equipment and construction management for the watercourse conversion.
