Rainwater challenge

Who can come up with the most creative way to collect rainwater at home?

Collecting rainwater is important for nature. You can reuse this water to water the flowers and plants in your garden. This saves clean drinking water.  

In addition, collecting rainwater during heavy rainfall prevents the sewer system from becoming overloaded and flooding.  

In this YouTube short, Floor explains how you can participate in the Rainwater Challenge: https://youtube.com/shorts/wfYAiSmr2X4?

What should you do?

Think of an original way to collect rainwater at your home. This could be outside, inside, in the garden, on the balcony, or even in the attic! Consider:

  • A specially designed collection system
  • A creative downspout
  • solution
  • Something involving plants, baking, or materials you already have
  • A real structure or a model
  • A drawing or design with explanation

Anything goes, as long as it's your own idea!
