Insufficient water quality

The quality of the water is insufficient.

When urine of (heavy) drug/medicine users ends up in the sewer unfiltered, it causes negative effects to the quality of both ground and surface water.


The Green Wall

The Green Wall is a plant wall which purifies wastewater. It is developed for "Tiny Tim", little, fully self-sufficient, houses. The Green Wall filters the wastewater of the little houses. Besides that, the plants can filter drug remedies from the water. Therefore, the plant wall can function as a pre-purification for urine of (heavy) drug/medicine users.


  • Less drug remedies in the ground and surface water.
  • The Green Wall can function as a pre-purification at a "normal" residential building.
