An unusual trip into a very hidden side of Brussels

Le réseau d’égouts sous Bruxelles-Ville

The sewer network under the City of Brussels is nearly 350 km long! Thousands of m3 of waste water flow through these 350 km of underground drains and tunnels every day.

The Sewer Museum invites you on an unusual trip into a very hidden side of Brussels but which is absolutely vital for the running of the city.

And unlike other museums, this one is active, with the River Senne playing the leading role. A museum that tells the story of when, why and how the sewers were built, describes the jobs that people do in this underground world and explains the city's water cycle.

In the event of heavy rain, for safety reasons, the Museum staff reserve the right to refuse access to the covered river and sewer.

Exhibition: Rebellious moods

The Museum is issuing a call for contributions to collect the photo's inscriptions, drawings or scribbles from the public toilets. The photo's received will be the subject of an exhibition at the museum: the loos are one of the rare public places which avoid widespread surveillance. It is, therefore, possible to express oneself anonymously; without censorship or risk.
