Old Emscher

The Old Emscher

The Old Emscher flows through the Duisburg-Nord Landscape Park for a distance of over three kilometres.

For many years the Old Emscher served as a surface disposal outlet, carrying waste water from industry and households in the whole of the Ruhr region in its straightened path.

Today waste water is carried by a subterranean pipeline. Since then, the culvert of the Old Emscher has been filled exclusively with rainwater. To enhance the recreational value of the Old Emscher, the river profile has been remodelled in recent years (see map). The newly created sections of the Old Emscher are now fed by precipitation channelled from sealed-off areas and roofs in the Landscape Park.
