Drinking Water

Prevention is better than cure

Thanks to the fact that Switzerland’s surface waters have been kept clean, this maxim has to a large extent been upheld. However, the presence of new (harmful) substances allows no room for complacency on this front. Globally, there is an urgent need for cost-effective and energy-efficient water treatment solutions on various scales - all the way through to wastewater recycling.
