**Wetsus - European Centre of Excellence for Sustainable Water Technology** is a research centre for water technology in [Leeuwarden](/source/Leeuwarden), [the Netherlands](/source/Netherlands). Over one hundred companies and twenty knowledge institutes work together at Wetsus to develop solutions for global water issues.[1]

## History

Wetsus was established as part of *Samenwerkingsverband Noord-Nederland* (a public-private partnership in the northern Netherlands, covering [Friesland](/source/Friesland), [Groningen](/source/Groningen_(province)) and [Drenthe](/source/Drenthe)), the Frisian Water Alliance, the [University of Twente](/source/University_of_Twente), the [University of Groningen](/source/University_of_Groningen) and [Wageningen University & Research](/source/Wageningen_University_%26_Research) to strengthen the position of the region as major player in the water sector.[2][3] In 2007 the institute was labeled [Top Technological Institute](/source/Technological_Top_Institute).[4]

## Collaboration

Together with other actors of the [WaterCampus Leeuwarden](/source/WaterCampus_Leeuwarden), Wetsus collaborates with several initiatives, such as:

- the Water Alliance to take technological innovations to the market,
- the *Centrum voor innovatief vakmanschap water* (Centre for innovative craftmanship water) for vocational education;
- the Centre of Expertise Water Technology (CEW) for collaboration in the applied sciences.[5]

Wetsus is home to the MSc Water Technology, a [joint degree](/source/Dual_degree) of the University of Groningen, the University of Twente and Wageningen University & Research.[6]

## Innovation & research

Wetsus studied [reverse electrodialysis](/source/Reverse_electrodialysis) to generate [osmotic power](/source/Osmotic_power). That research resulted in a spin-off company called REDstack that generates [blue energy](/source/Blue_energy) at the [Afsluitdijk](/source/Afsluitdijk) in the Netherlands.[7] Wetsus also promoted [decentralized sanitation](/source/Decentralized_wastewater_system) and wastewater reuse in the Netherlands through the spin-off company DeSaH.[8][9]

As of 2024, research is focused on removing [PFAS](/source/PFAS) from water, and the removal of [micro and nanoplastics](/source/Microplastics) from water.[10][4]
