Wetsus Mission
Wetsus develops key enabling water technologies to foster a sustainable and fair society in a healthy and circular environment. To achieve this, 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 that shape innovations towards fruitful implementation, and where graduates become leaders in sustainable innovation.

Wetsus is part of WaterCampus Leeuwarden.

WaterCampus Leeuwarden is the physical core of the Dutch water technology sector and has the ambition to play a sector uniting role for the rest of Europe as well.
WaterCampus stimulates cooperation between (inter)national businesses, knowledge institutes and governments within the water technology sector, in order to create synergy for world class innovation, education and entrepreneurship.

This strengthens the global position of the European water technology sector. Additionally, WaterCampus offers a unique research infrastructure, and is a meeting point for scientists and companies from all over Europe.
The international cooperation organized and stimulated by WaterCampus Leeuwarden leads to knowledge, talent and entrepreneurship that contribute to solutions for global water problems.

Why Wetsus?

Wetsus, European centre of excellence for sustainable water technology, facilitates breakthrough innovations for water treatment technology.

Wetsus is a facilitating intermediary for trend-setting know-how development and uses a unique innovation model. Wetsus’ main activity is the coordination of a world leading research program. The inspiring and multidisciplinary collaboration between companies and research institutes in Wetsus results in innovations that contribute significantly to the solution of the global water problems.

Wetsus is organized around its aim to stimulate collaboration between the various public and private organizations that together constitute the water sector: i.e. between public companies, private companies and universities; between scientific chairs; and between regional, national and European policy makers. The Wetsus Open Community Cooperation Model (see figure) creates the synergy and momentum required to achieve major objectives. As per January 1, 2024, 105 companies annually invest some € 3.4 million in the demand driven € 16 million/year research program, with a long-term commitment. In the current Wetsus international know-how network, about 130 partners from all over the world, but with an emphasis on the EU, join forces in solving the global water problems.

Wetsus is a not-for-profit foundation located in Leeuwarden, the Netherlands. In 2022, the Dutch government has appointed Wetsus as national institute for strategically important research (Dutch: SBO-instituut). Wetsus combines a campus approach with an international know-how network strategy. At WaterCampus Leeuwarden, multidisciplinary know-how, education and talent are concentrated, valorization and commercialization are accelerated and facilities are shared.

Companies, assembled in a Wetsus research theme, together determine the research program, which is executed in the Wetsus laboratory by the 26 involved research institutes. All research projects are performed under the responsibility of the participating universities. As per January 2024, 48 scientific chairs from all over Europe are involved.

Within the (inter)national scientific programs in Wetsus, research institutes and industry jointly implement market-driven, application-oriented, multidisciplinary, (pre)competitive scientific research in the field of sustainable water technology. This is typically done in four year-long research projects carried out by PhD students and their supervisors.

The research goal of Wetsus is to develop innovative and sustainable water technologies.
The scientific creativity required for that is to a large extent generated by the unique cooperation of over 50 know-how disciplines in one physical laboratory.

A dedicated Intellectual Property Rights policy is in place, to enable optimal cooperation, innovation and the commercialization thereof. This has proven to lead to successful innovations.

Innovation, partnership, reliability, joy and cooperation are the values around which all Wetsus’ activities are performed.

Wetsus’ distinguishing key success factors are: High trust cooperation through relatively small research themes, high commitment through long term cooperation contracts with companies and secondment agreements with universities, sharing of multidisciplinary knowledge from universities and companies in an idea driven program, strong involvement of SME’s, independent meeting place for scientists from all over Europe and valorization and commercialization support from WaterCampus Leeuwarden.

Regarding involvement in policy and programs for innovation, Wetsus is active on regional level (smart regional specialization in the Northern Netherlands), national level (direct involvement in national topsector Water & Maritime and TKI water technology) and European level (as member of Water Europe, ERRIN and the Water4All partnership, and as coordinator or partner in Horizon Europe, Interreg and LIFE projects).

In addition to Wetsus’ research role, Wetsus also fulfills two other main functions. A talent and education program is operated, in order to develop the human capital required to fulfill the innovation ambitions of the international water sector. Further, many activities in the field of stimulating spin-offs and entrepreneurship are performed to stimulate the translation of laboratory inventions into actual innovations applied in society.
