About :

There are 1,700 kilometers of sewers in Stuttgart's underworld. Dark canals, countless street drains, and huge overflow basins are the city's specialty. They are cleaned, checked, and repaired so that the sewage ultimately flows where it belongs: into the sewage treatment plants. 00:00 Out and about with sewer cleaners The city's drainage department has sewage under control: it shouldn't end up in the groundwater or the Neckar. Employees ensure this not only during the day, but often during night shifts too. 00:39 A dark, smelly affair Before the sewer maintenance team goes underground, a probe is used to measure whether there are any dangerous gases. Then they go ten meters down into the darkness, at least three people for safety reasons. The sewer inspections are intended to discover damage and remove large objects. The mixture of rainwater, waste water, and feces creates an unpleasant stench. 04:15 Gullies also need to be cleaned All kinds of waste ends up in the city's many gullies. The surface drainage system cleans the street drains so that they do not become blocked. This is particularly difficult when there is a lot of traffic - especially in tunnels and underpasses. The team therefore often works at night. 07:07 Remote-controlled through the sewer In Stuttgart-Sonnenberg, the connection of a new house to the sewer needs to be checked. To do this, a remote-controlled camera drives through the sewer. Sewer inspector Dirk controls the camera from the surface and decides whether or not to remove a connection. Elsewhere, a high-pressure cleaning sled, also remote-controlled, is used to free the particularly dirty sewers of deposits using water pressure. 11:09 What happens when there is heavy rain? The sewer beneath Stuttgart's Zuckerberg is being cleaned for the first time since it was built over 20 years ago. It is over two kilometers long and cleaning takes several months. The deposits have formed sewer sand, which is gradually being removed. Another important canal runs under the palace gardens: the Nesenbach Canal. But in heavy rain, the overflow basin can also reach its limits, and the excess water then flows into the Neckar. #underworld #underground #job Subscribe to the Landesschau channel: http://x.swr.de/s/landesschauabo Welcome to the official YouTube channel of the SWR Landesschau!
