Drinking Drinks Water Share Water means sharing 30L of drinking water with those who don't have it! They represent 1 out of 3 people in the world. Why 30L? Because according to the WHO, a human being needs at least 20L to meet their vital needs. And 10L more is no worse. All this is made possible by the NGO Vision du Monde, our partner, which acts all over the world. With nearly 70 years of recognized expertise, they give access to drinking water to a new person every 10 seconds. Together, we can contribute to a better world. It's cool! And that feels good.
