, Germany, North Rhine-Westphalia, Oberhausen - Renaturation of the Emscher in the Holtener Bruch. On the right, OQ Chemicals' Ruhrchemie plant. The currently straightened Emscher, here at high water level, regains its curves and can meander through its new floodplain. The ecological conversion of the Emscher system consists of the construction of a central sewage system in the Ruhr area, the construction of sewage canals and the renaturation of the Emscher and its tributaries. The Emscher has been completely free of sewage since January 2022 following the construction of a parallel sewage canal. The river was previously an open, above-ground combined sewer with rainwater and wastewater.
