Bøtø Nor Pumping Station was constructed in 1871 in connection with the reclamation of Bøtø Nor on southern Falster, Denmark. The building was listed in the Danish registry of protected buildings and places in 1970. It now houses an exhibition about the enterprise and the 1872 Baltic Sea flood.

History

Bøtø Nor was a lake, 15 km long, 1 km wide and up to 2.8 m in depth, which had been formed by natural sand deposition along the southeast coast of Falster.

The first plans concerning reclamation of Bøtø Nor were presented in 1762. An unsuccessful attempt to drain the most shallow part of lake was made in 1790. The plans were in 1860 finally revived by Edward Tesdorpf. Tesdorpfm who was a prominent politician and president of the Danish Agricultural Society (landhusholdningsselskabet), was the owner of Orupgaard and Gedsergaard. He envisioned the project as a model for other similar projects in other parts of the country. He was the driving force behind the foundation of I/S Bøtø Nors Udgravnings- og Inddæmnings-selskab. A dyke, 19 km long and 3 m tall, was built along the coast and a system of canals was also constructed. Bøtø Nor Pumping Station was built at Marrebæk in 1870–71. It contained a Burmeister & Wain steam engine and a wooden Archimedes' screw.

The 1872 Baltic Sea flood left Bøtø Nor flooded but the pumping station survived. The dyke was later rebuilt and heightened.

The pumping station was modernized in 1901. The old B&W steam engine was replaced by a new Atlas engine. The wooden Archimedes' screw was replaced by an Archimedes's screw made out of steel. An additional Archimedes' screw operated by a vind wheel was also constructed at this point but removed again in 1919.

A small new pumping station for supplementing the old one during peak time situations was constructed in 1949.

The old Bøtø Nor pumping station was decommissioned when a new one was inaugurated at an adjacent site in 1967. The new pumping station was constructed at a cost of DKK 2,000,000. The first of six electrical pumps was started on 15 November 1979.

Today

The building has later been restored and converted into a working museum.

The new pumping station is located immediately to the southwest of the old building. It has a capacity of 6.400 l/second or 55.2 million l/day. It drains the land into a depth of 3.5 metres.
