Over 70% of our planet is covered with water. This apparent wealth takes on a new meaning when we consider that only approximately 3% is fresh water. From the very beginning of human development, this water has meant life to us – both to drink and to water our fields and animals.

As technology advances, we create ever new forms of process water and wastewater. Thus a responsible approach to the handling of this precious element is now, more than ever, the key to progress in our world.
