What Wetsus does

Wetsus is a not-for-profit foundation headquartered in Leeuwarden, Netherlands, that operates as a European centre of excellence for sustainable water technology. Founded in 2003, the organization runs an open innovation community model connecting 108 for-profit companies with 50 scientific chairs from 28 European research institutes across 10 countries. The combined research network comprises approximately 140 partners spanning water utilities, industrial companies, universities, and government bodies, all collaborating on pre-competitive water treatment research. Wetsus does not sell products directly but rather functions as a facilitating intermediary that generates and transfers water technology IP to its participants, evidenced by 1,057 scientific publications, 344 completed PhD projects, and 106 patents transferred to society.

The organization's research program is structured around approximately 50 research themes organized within four focus areas: Sustainable Water, Recovered Resources, Drought Resilience, and Healthy Environment. Specific themes include advanced coagulation for nanoparticles, desalination and concentrates, phosphate recovery, integrated PFAS treatment, bioplastics from water, biofilm engineering, and sustainable carbon cycle research. Wetsus hosts advanced laboratory infrastructure at WaterCampus Leeuwarden, including ML-II level microbiology facilities, advanced microscopy, high-voltage labs, fermentation equipment, and analytical instruments such as LC-MS/MS, ICP-OES, SEM-EDS, and whole-genome sequencing platforms. The organization also operates membrane production and nanofiltration pilot systems, reverse electrodialysis stacks, and anaerobic glove boxes for biofilm research. Notable inventions include the ViviMag magnetic phosphorus and iron recovery process (co-developed with TU Delft, which won the International Water Prize), the Hyperbolic Vortex Plasma Reactor for groundwater aeration and PFAS degradation, and electrochemical nutrient recovery systems.

Wetsus's revenue model rests on three primary streams: company theme participation fees, platform membership fees, and public/government funding. Companies pay €35,100 per theme per year for standard participation, with a reduced rate of €21,100 for companies with turnover below €3 million. Platform memberships range from €4,250 to €14,000 annually depending on company size. As of January 2026, 108 companies contribute approximately €3.7 million annually toward the €18 million/year research program, with the balance funded by Dutch government long-term financing (secured via the 2022 SBO-instituut designation), and EU programs including Horizon Europe, Interreg, and LIFE. The pre-competitive research outputs are commercially implemented by participating companies, making Wetsus a structurally novel research-as-a-service platform for the European water sector.

Core offering

Wetsus is a not-for-profit foundation that runs a demand-driven, subscription-based open innovation program in sustainable water technology. Companies and universities co-fund and co-execute pre-competitive research across 50 themes in four focus areas (Sustainable Water, Recovered Resources, Drought Resilience, and Healthy Environment), with research performed by PhD students in Wetsus's advanced laboratories at WaterCampus Leeuwarden. The foundation transfers resulting patents and know-how to participating companies for commercialization, and also delivers education programs such as the MSc Water Technology and an Executive Water MBA.

Product overview

Wetsus is not a product company but rather a European centre of excellence for sustainable water technology that functions as a facilitating intermediary for know-how development. It operates as a research institute that brings together companies and research institutes to develop water treatment technologies. Wetsus creates an innovation community via trust-based networks of companies, universities and public bodies for generating, testing, and evolving innovative ideas and science-based approaches within interdisciplinary PhD programs. The organization has multiple research themes including Advanced coagulation for nanoparticles, Advanced water treatment, Applied water physics, Biofilms, Biopolymers from water, Desalination & Concentrates, Engineered soil amendments, Groundwater technology, Integrated PFAS treatment, Monitoring & Quality, Natural flocculants, Natural water production, Phosphate recovery, Priority compounds & Virus control, Resourceful sludge dewatering, Smart water grids, Source separated sanitation, Steering soil microbiomes, Sulfur, Sustainability in the Making, and Sustainable carbon cycle. Wetsus coordinates European research projects such as RecaP, Water Mining, REPARES, ReFARM, SCALIBUR, NEWBIES, iWATERMAP, ViviMag, BAoBaB, Health-i-care, RM@Schools, REvivED Water, MEDUWA Vecht(e), SVFA_project, BioElectroMet, Capmix, Denewa, and WaterSEED. The organization does not offer commercial products for sale but rather develops technologies that are transferred to participating companies for commercialization.

Direct peers

• KWR Watercycle Research Institute: Dutch water research institute participating in Wetsus as a know-how institute. Both organizations conduct applied drinking water and wastewater research, share PhD supervision, and co-publish in the same peer-reviewed water technology domains.
• Deltares: Independent Dutch applied research organization for water, subsurface and infrastructure. Participates in Wetsus as a research institute and conducts overlapping research in water treatment, resource recovery, and climate-resilient water systems.
• Eawag (Swiss Federal Institute of Aquatic Science and Technology): Switzerland's leading water research institute, combining aquatic science and engineering across drinking water, wastewater, and ecology — a direct functional peer to Wetsus's multidisciplinary water technology mission, although nationally focused on Switzerland.
• UNESCO-IHE Institute for Water Education: Institute for water education and applied research, affiliated with UNESCO. Comparable on the education and capacity-building side (MSc/PhD programs, professional training) that Wetsus also delivers through its MSc Water Technology and Water MBA programs.

Broad incumbents

• IWA Publishing / International Water Association (IWA): Global network and convening body for water professionals. Comparable in that it brings together researchers, utilities, and industry on water topics, but operates as an industry association rather than a performing research lab.
• Water Environment Federation (WEF): US-based technical and educational water organization covering wastewater treatment research, education, and standards. Operates a much broader remit than Wetsus but is a comparable convening/publishing platform for water research and technology.

Regional players

• Water Research Australia: Australia's collaborative water research and innovation center, performing industry-funded research with utilities and universities. Functionally similar collaborative model to Wetsus, but serving the Australian market rather than Europe.

Emerging players

• Nijhuis Saur Industries: Industrial water treatment technology company and Wetsus corporate participant. Comparable in that it commercializes technologies originating from Wetsus research themes and operates at the boundary between research and applied water treatment.
• Paqell (Paques / Shell joint venture): Joint venture commercializing THIOPAQ biological desulfurization technology. Has supervisory board representation at Wetsus and a Wetsus-origin technology lineage — comparable as a commercialization vehicle for Wetsus-derived IP.

Others

• European Innovation Council (EIC) Water Programs: European-level funding and convening vehicle for water and cleantech R&D, including programs that overlap with Wetsus themes. Comparable as an ecosystem enabler for water innovation, though operating as a funder rather than a performing research lab.
