THE GREEN WALL OF FERLA

In Ferla, innovation meets sustainability with Wall2Water (W2W), a pioneering project that transforms the “Valle dell’Anapo” school building into a self-sufficient living organism.

This green wall is not merely an ornamental element, but one of the first European infrastructures of its kind, part of the international NAWAMED program.

The system functions as a natural purifier integrated into the architecture: water from the sinks is pumped along the façade and filtered through plant modules where bacterial biofilms and roots eliminate impurities.

In addition to promoting biodiversity, this technology allows for the saving of approximately 260 cubic meters of drinking water per year, covering a quarter of the school’s toilet flushing needs.

With a surface area of 30 square meters, the wall of Ferla represents an open-air laboratory studied by international experts, demonstrating how nature-based engineering can reduce environmental costs and educate new generations on the value of water resources.
