Kläranlage Duisburg Alte Emscher

The Kläranlage Duisburg Alte Emscher is a sewage treatment facility in Duisburg in the Ruhr region. It uses biological processes to clean wastewater before releasing it into the Rhine River.

The facility opened in 1936 with a circular basin design. It received major upgrades in 1988 to add modern biological treatment and later expanded to handle wastewater from neighboring cities.

The facility shows how industry in the Ruhr region depends on water management and cleaning. Visitors can see the connection between factories, homes, and the river that receives treated water.

The facility is located near the Rhine River and connected to pumping stations throughout the area. Best to view it from the outside or join a guided tour, as this is an active industrial site with safety restrictions.

Wastewater from major factories like ThyssenKrupp flows here alongside sewage from a local brewery. The biological cleaning method relies on living organisms to break down pollution naturally.
