Koning Willem-Alexander gemaal, Water pumping station in Katwijk aan Zee, Netherlands
The Koning Willem-Alexander pumping station is a water management facility in Katwijk aan Zee with three large screw centrifugal pumps housed in concrete casings. The installation regulates water levels by directing flow through the Katwijkskanal toward the North Sea.
The original water control system began in 1806 as a sluice mechanism and was replaced in 1881 by a steam-powered station. The current concrete structure was built in 1954 and represents a shift to modern pumping technology.
The station blends functional post-war design with decorative elements created by sculptor Hans Petri, including a bronze statue. These touches reflect how locals view this facility as more than just machinery, but as part of their community's relationship with water management.
The facility sits directly on the coast and is visible from the nearby beach promenade. Access is straightforward from local roads, though visitors should note that entry to the interior is generally restricted to personnel only.
The facility was renamed in 2013 to honor the current king's early work in water management before he became monarch. This naming choice reflects how the Dutch connect their monarchy with practical engineering achievements.
