Paris Sewer Museum

The Musée des Égouts de Paris is located in the 7th arrondissement beneath Place Habib-Bourguiba, directly across from the Quai d'Orsay. The nearest public transportation options are the Alma-Marceau Metro station on Line 9 and the Pont de l'Alma RER station. The museum tells the story of the Paris sewer system, the tools and machines used to maintain it, and the history of urban sanitation. It aims to raise awareness of how we handle waste and to remind visitors that the sewer is not a trash can. A visit usually takes between 45 and 60 minutes and leads you through several themed rooms, including the Galerie Hugues Aubriot, the Galerie Pierre-Emmanuel Bruneseau, the Alma vault, the Bosquet collector sewer, the Galerie Eugène Belgrand, and the Galerie Adolphe Mille.

Visitors can explore about 500 meters (roughly 1,640 feet) of real, working sewer tunnels. These include the Alma pumping station, a confluence point, and several collector sewers. The exhibition displays historic cleaning equipment, such as cleaning balls that were still in use into the 2000s, as well as instruments for regulating and monitoring water quality. One section also presents the equipment, hazards, and duties of the sewer workers. The average temperature in the museum is 13 degrees Celsius (55°F), and high humidity and unpleasant odors are possible.

Guided tours of the sewers have been offered since the 1867 World's Fair, often with boat rides or special wagons at the time. During World War II, the sewers were closed to visitors because they served as a shelter and meeting point for Resistance fighters. The museum has existed in its present form since 1975, though the boat rides are no longer offered. Following a major renovation that included wheelchair-accessible entry and a new reception hall, the museum reopened in October 2021. It is open daily except Mondays from 10 a.m. to 5 p.m., but closes when the Seine floods.
