As you enter the museum, you descend into the sewer system itself, you get to learn about the different sewer levels around and how this system is upheld, while walking closely to the sewer pipes. The tour intermixes walking around pipes that are used today, and older pipes that are outdated and are abandoned. Above these is the history of the Parisian sewer system, from different view points, including drawings from different time periods. Though today the sewers are updated, the tours include a few alleyways of the older systems, that are located down there just for display.
Beyond the tour, you can see photos from the history of the sewage of Paris, and get exposed to different maintenance methods that these difficult logistical pipes require.
Visitors on this tour are asked not to bring food, and at the end of the tour are requires to wash their hands.
The divided sewage system is something of an achievement for the capital's residents from the 13th century, when King Philip August gave the order to build the drainage channels. At a certain point Napoleon ordered to have these channels moved underground, and in 1850 began the building of the sewage system that today reaches more than 2,100 kilometers of tunnels.
Until the 1970's, the sewage system was a fascinating tourist destinations that rode around in carriages, and later by walking tours. Today tourists are satisfied by visiting the museum, which has managed to turn this stinky topic into a chic place to visit. Here you can learn all about the Parisian sewage system.
The museum is located under the Pier d'Orsay, on the left bank of the Seine.
If you go on one of the hour long tours, you will be able to see the photos exhibited about the materials that were developed over the years to maintain and repair the sewage pipes. Massive wooden balls that were used for cleaning the pipes, maps that show the expansion of the tunnels by the architect Eugène Belgrand, and dolls dressed in uniforms of sanitations from different time periods.
