Old pumping station, Technology museum in Findorff, Germany

The Old Pumping Station is an industrial museum in Findorff that displays wastewater treatment technology through preserved machinery and equipment. The building keeps the original machine hall with its working installations, documenting how pumping and filtering technology developed over more than a century.

The facility was founded in 1913 and operated as a pumping station for Bremen's sewage system, directing wastewater to the Weser River until 1994. Its closure marked the end of an era for industrial city infrastructure in Bremen.

The site is run by the Altes Pumpwerk association, founded in 1997 by former employees of the pumping station. In November 2010 the association received the Bremer Denkmalpflegepreis for its volunteer work in maintaining and expanding the complex. The grounds also hold a hall, a dwelling house and a washhouse.

The museum occupies the main pumping station I on the corner of Salzburger Straße and Bayernstraße in Findorff. Visitors can see the machine hall and the exhibition on sewage history, and can descend into an underground sewer channel. The site is run by the Altes Pumpwerk association, founded in 1997 by former employees, with support from hanseWasser Bremen.

The site is a listed ensemble: main pumping station I, the old pumping house, a hall, a dwelling and a washhouse, protected since 1995. The buildings were designed by Bremen's Hochbauamt and erected 1913–1915 in Reformarchitektur style with neo-baroque elements.
