The WaterFoundation has become, step by step, an organizational focus for committed individuals who, despite differences of background and outlook, are united in the pursuit of a common objective: the realization of the human right of access to water.

The key elements of a dignified life, to which people everywhere are equally entitled, include adequate water supplies, easy access to clean drinking water, the preservation of biological diversity, and sustainable climate protection. For the trustees, directors and team members of the WaterFoundation, these requirements are both a vision and a concrete goal.

We are united, moreover, by the conviction that the people in our project countries can only solve their specific water problems for themselves. To do this, they need financial support but also technical expertise and an understanding of the relevant ecological factors.
