UNESCO World Heritafe Ir. D.F. Woudagemaal, Lemmer

The ir. D.F. Woudagemaal is a pumping station in the Netherlands, and the largest still operational steam-powered pumping station in the world. On October 7, 1920 Queen Wilhelmina opened the pumping station. It was built to pump excess water out of Friesland, a province in the north of the Netherlands.
In 1967, after running on coal for 47 years, the boilers were converted to run on heavy fuel oil. It has a pumping capacity of 4,000 m³ per minute, 1,000,000 GPM. The pumping station is currently used to supplement the existing pumping capacity of the J.L. Hooglandgemaal in case of exceptionally high water levels in Friesland; this usually happens a few days per year.
