More stability. Fewer emissions.

We help you achieve better effluent values for your WWTP, save costs, and reach your climate targets.

Research meets years of practical experience

Our team combines diverse expertise with years of experience. This results in practical solutions that connect scientific insights with the demands of everyday operation. For almost any question, we have the right contact person for you.

Swiss Technology

From research to practice: as a spin-off of Eawag, upwater brings scientific Swiss innovation into everyday use. Precision, robustness, and reliability form the foundation of our technologies and evaluations – for results you can rely on.

How do we do that?

New tools, practically applied. From measurement technology and laboratory analysis to data analysis and optimization.
Our solutions create process understanding, increase operational stability, and enable sustainable improvements at wastewater treatment plants.

Environmental Importance

Net Zero by 2050 is a nationwide target for WWTPs in Switzerland. Without reduction measures, the share of emissions from WWTPs will rise into a critical range.
