Cruquius-gemaal in werking. / Cruquius-water pump station, working.

This is the Cruquius water pump station in action. For fun and no longer powered by steam, these days: it's a museum about the Dutch life with water. This pump station's technology is British. It was originally devised to remove water from Welsh coalmines. In The Netherlands, it was used to make land where there used to be water. In this case, the Haarlemmermeer.
