This historical sewage treatment plant is not an ordinary museum. A historic building with unique underground spaces offers unusual leisure activities. Step into the industrial age and discover the original purpose of this national monument. The old sewage treatment plant in Prague is an important site for documenting the history of architecture, engineering and water management. It was built between 1901 and 1906 as the final part of the Prague modern sewer system. The British civil engineer William Heerlein Lindley was responsible for creating the sewer system and the technical parameters of the treatment plant. The mechanical treatment plant worked until 1967 and was formally designated a historic landmark in 1991, from 2020 is listed on the Tentative list of the Czech Republic
Large parts of the underground facilities can be visited on a guided tour. This site is Europe's only living example of a mechanical wastewater treatment plant at the turn of the 19th and 20th centuries which is that well preserved and open to visitors. The old (historical) treatment plant, together with adjoining plants, located close to each other (the existing WWTP from 1967 and the new water line of the 21st century) is a unique testament of the development of a significant water sector.
