The Emschermünde sewage treatment plant , or KLEM for short, is one of four central sewage treatment plants on the Emscher . The facility is located on the city limits between Dinslaken , Oberhausen and Duisburg . The operator is the Emschergenossenschaft .

The plant was built in 1976 and at that time, with an area of ​​75 hectares, it was the largest sewage treatment plant in Europe with a biological treatment stage. The catchment area is 774 km², around 910,000 inhabitants and 930,000 population equivalents are connected. Over 400 million cubic meters of wastewater are treated every year. In dry weather, the river treatment plant treats all the water in the Emscher, that is around 10,000 liters of water per second. Heavy rain can lead to untreated wastewater being discharged into the Rhine. In extreme floods such as 1981 and 1995, the sewage treatment plant is sealed off and the Emscher flows off uncleared.

In 1994/95 the system was supplemented with additional rows of basins for the breakdown of phosphorus and nitrogen, and in 2001 it was modernized again. Another adjustment was completed in 2019 as part of the conversion of the Emscher system . The Emschergenossenschaft invested around 145 million euros in converting the sewage treatment plant. With this measure, the system was adapted to the future new Emscher system with the Emscher sewer.

The three digestion towers are striking and visible from afar . The HOAG route leads past the site. The Emscher estuary sewage treatment plant is part of the route of industrial culture .
