5 pm - 10 pmYou will have the opportunity to see a section of the sewer system in Praga – a stormwater overflow chamber at the intersection of Ratuszowa and Jagiellońska streets. This underground facility is usually inaccessible to the public. It was built over 100 years ago according to the design of the famous English engineer W.H. Lindley, but wastewater still flows through it today. Odor sensations are guaranteed! The event is only open to adults with valid identification. If it rains, tours will not be possible for safety reasons. Tour duration – 15 minutes.
The event is free of charge. No registration or prior notification required. Intended for specific audiences. The tour takes place during designated hours.
