The International Association of Water Works in the Rhine Basin (IAWR) acts as an umbrella organization for the following organizations and their members.

These organizations represent 120 water utilities in the six countries along the Rhine River: Austria, Switzerland, Liechtenstein, France, Germany and the Netherlands.

The roughly 30 million people living in this area depend on the Rhine, its tributaries and the lakes in its catchment area for the provision of drinking water.

The IAWR feels responsible for the sustainable management of these water resouces.

The aim of the IAWR is to protect the Rhine, its tributaries and the lakes in the Alpine foothills so that so that it is possible to supply drinking water from them using natural treatment methods only.
