“We all have dry feet, but what needs to be done to keep it that way?”, says miller Ger Nagtegaal. In the mini-polder that they want to build in Nieuwegein next to the Poldermolen OUdegein, children can learn about water management in the Netherlands. With a sluice a piece of land can be flooded and pumped dry again with a wheel. Nagtegaal: “It is to provide insight into what the mill does, and what the mill has also done in the past to keep the land dry.”
