The water garden is a water feature: a pond, a network of canals and systems for collecting rainwater. This is an attempt to bring back an aquatic ecosystem and to give water a new place in the landscape of the wasteand. In addition, it experiments with new techniques for water treatment in the city.

  

The water garden emphasizes the importance of biodiversity in the city and, on a small scale, is a source of inspiration for the development of the park, for the river basin of Maelbeek, or for the city as a whole.

  

Thanks to this experiment, the issue of water quality has come to the fore and a series of other experiments with filtration and the measurement of water quality parameters have been introduced into this space.
