Essen, North Rhine-Westphalia, Germany - High river dikes as flood protection. The Emscher River has been completely free of sewage since January 2022 following the construction of a parallel sewer. The river was previously an open, above-ground wastewater canal, combined sewer with surface water and sewage. Walkers stroll along the Emscher-Weg, a bike and foot path along the Emscher.
