Germany: Growing Cologne needs bigger sewage pipes to cross the Rhine • Water News Europe
Published on by Esther Rasenberg, Water News Europe
In the German city Cologne, between the two banks of the Rhine, two 90-year old pressure pipes of 470 meters cross the river under the Rhine bed, to bring wastewater from one side of the river to the Waste Water Treatment Plant (WWTP) on the other side. Due to a growing population Cologne’s wastewater company (StEB) needs to replace these pipes. StEB is investing 60 million euros and wants to start with the job in 2021.
