Ehemaliges Pumpwerk Uerdingen, Art Nouveau industrial building in Krefeld, Germany

The Ehemaliges Pumpwerk Uerdingen is a listed industrial complex at Rundweg 20 in Krefeld-Uerdingen, built 1908–1910 to plans by Georg "Jörg" Bruggaier with Hubert Hentrich and engineer Krawinkel. Its main hall holds two sewage channels, an overflow channel, a narrow-gauge rail line, three sluice gates and a hall crane; a separate machine hall housed the flood pumps. Usable floor area is about 857 m².

Built between 1908 and 1910 to plans by architect Georg "Jörg" Bruggaier, with Oberbaurat Hubert Hentrich and city engineer Krawinkel involved, the plant treated wastewater from the harbour and above all from neighbouring Krefeld on its way to the Rhine. It ran in its original form until 1962, then continued as a pumping station with screw pumps until 1996, when a new station beside it took over. The site then lay fallow until restoration began in 2018.

The building shows how the city managed water and sewage in the early 1900s by combining function with artistic design. The rounded windows and curved forms reflect the Art Nouveau idea that technical buildings could be beautiful too.

The site on Rundweg 20 has been under restoration since 2018, so the halls and technical rooms are not open for tours; the complex is best viewed from the surrounding paths. It stands among trees near the Rheinhafen Krefeld and the B288, and the Schieberhaus at the edge remains in the possession of the Kommunalbetrieb Krefeld.

The site retains a Bremsberghaus, a small building used to overcome the height difference and lift the sludge onto the surrounding land by means of a narrow-gauge trolley line. The main hall also keeps its hall crane, three sluice gates and two treatment channels.
