Despite the historical presence of public water fountains in most of the large cities of the world, city inhabitants still hesitate to drink that “street water” and prefer to buy a plastic bottle, which is pollutive. However, these fountains are tested and their quality very high because of health norms. In Paris, Wallace fountains are icons of the urban landscape. Designer Emanuele Pizzolorusso conceived Phil The Bottle, a bottle that indicates for each town where to find these fountains, and lead the user to get back to eco responsible behaviour by using back these fountains. Who said design and ecology don’t fit ?
