On September 15, you will get the rare chance to dive into Old Town’s sewer system for a guided tour.
The sewers lead from Old Town Hall down Pařížska street and underneath the Vltava at Čechův most, continuing under Korunovační street and Stromovka park in Prague 7 before winding up at the city’s Sewage Plant in Bubeneč.
The old wastewater treatment plant in Prague-Bubeneč is an important witness to the history of architecture, technology, and water management. Built in 1901-1906, it was used for the treatment of most of the sewage water in the city of Prague until 1967. In the steam engine room, one can view the still-functioning machines from the early 20th century.
The water system connects areas of Prague 1, 2, 3 and partially Prague 5, forming a confluence of collectors from Malé náměstí, Melantrichova Street, Železná and Celetná Street.
Registration to the event is free and will open on the PVK website (Prague’s waterworks and sewerage company) on August 26; spots are quickly filling up. Total length of the journey: three kilometers.
Visitors must bring their printed ticket or show it on their mobile phone. The first tour starts at 9:30, the last one at 16:30. Meeting point in front of the door to the right of the Astronomical Clock. The tour takes about twenty minutes.
