Today the group headed to the north-western outskirts to visit Dresden’s main sewage treatment plant. About 55 million cubic meters of waste water flowing annually through the city’s 1.700 km (!) long sewer network are mainly treated here. After a short introduction, the group adventured underground to see the first step of the sewage treatments and subsequently followed all the procedure it takes to clean the incoming water. The newly constructed biological treatment plant and the sludge treatment facilities make it possible that the waste water after the treatment has a quality like natural water again.
