Flooded houses, cellars and recreational parks. Could something like this happen again?
“The chance that flooding will occur next winter is small, but cannot be completely ruled out.”
What have you done last year to prevent this?
“Rijkswaterstaat is extra alert during high water and informs dike and flood defense managers and other stakeholders in the IJsselmeer area in a timely manner about the possible occurrence of high water levels. To this end, they continuously monitor the situation. This is done in close collaboration with the KNMI.”
“In addition, administrators from municipalities, Rijkswaterstaat, water boards and the Safety Region discussed with each other how they can work together better in the event of high water. It was agreed to improve the information provision between the various partners, as well as communication with residents and companies in the area outside the dike. An agreement has also been made to meet annually before the start of the storm season to discuss the latest developments.”
Six pumps at Den Oever
Being at Den Oever this year six pumps installedWith the pumps, Rijkswaterstaat will soon also be able to drain water to the sea if discharge cannot be done due to a high water level in the Wadden Sea. “The pumping station and the two pump groups are expected to be ready at the end of 2026. Before that happens, we will further complete the area around the pumping station. After construction, there will be another process in which we install, fine-tune and test all sensors,” says Rijkswaterstaat. .
It’s not yet 2026, so this year can still be exciting?
“The municipality of Hoorn is warned earlier by the Safety Region if flooding is likely to occur due to high water. In the sewer system of the Visserseiland outside the dike, valves have been installed in various places in the sewer so that the sewer for the waste water of Visserseiland residents can continue to work at flooding. The managers of the Grashaven have placed the electricity points higher to prevent damage from high water. Manhole covers have also been raised so that they are not immediately flooded.”
Is the water in the IJsselmeer and Markermeer now at such a level that damage and nuisance can be prevented in the next storm?
