What impact does flooding have on you?

90%

Up to 90% of rainfall in cities cannot seep into the ground.

In major cities like Cologne, heavy rainfall events are becoming more frequent and more intense. Short, severe downpours can release large volumes of water within just a few hours – volumes that drainage systems simply cannot handle.

According to the Intergovernmental Panel on Climate Change, the frequency of extreme rainfall has already increased and will continue to rise across Europe. Streets, basements and underpasses can flood within minutes. For residents, this means property damage, restricted mobility and growing safety risks. The areas hit hardest are densely built and heavily sealed neighbourhoods – without enough open space to absorb and retain the water.
