Reducing health and environmental risk

Every year, SUEZ invests in research and innovation to improve the quality of water supplies. We develop new technologies in our dedicated research laboratory to eliminate emerging pollutants, and work alongside local and international regulatory authorities for the protection of human and environmental health.

Fighting new pollutants in water

Shifting consumer habits have resulted in the appearance of new pollutants. These micro-pollutants are fast becoming one of the main ecosystem protection challenges facing local authorities and industry. We’re leading the way in addressing this mounting challenge through pioneering research and development studies at CIRSEE (International Center of Research into Water and the Environment), our Paris-based expertise and research centre.

“Micro-pollutants are the key challenge for tomorrow’s wastewater. We are very proud to protect a population of more than 2.5 million from those emerging contaminants with SUEZ processes built around ozonia® ozone systems.”

Collaborating with leading international experts

SUEZ is working with world-leading teams from universities in France and across the globe, harnessing this combined expertise in the biological effects of exposure to micro-pollutants to meet the challenges posed by this new class of pollutants. Together, we are investigating the effectiveness and benefits for consumer health and developing plans to prevent future sanitation risks.

Innovation and collaboration in Lausanne, Switzerland

In 2011, we partnered with the city of Lausanne on a program designed to enrich its knowledge of micro-pollutants. The program tested several innovative solutions, and the combination of two leading-edge technologies: oxidation by ozone and absorption on a pulsed reactor of powdered activated carbon. This game-changing technology resulted in the city contracting SUEZ to implement an unprecedented system that completely protects Lake Geneva. On 1 January 2016, Switzerland became the first country to introduce legislation on the treatment of the micro-pollutants present in wastewater. In May 2016, EPURA – a limited company belonging to the City of Lausanne, supported by the engineering consultants BG Ingénieurs Conseils SA and Holinger SA – chose SUEZ and its Swiss partner TECHFINA to build the facilities to treat wastewater, micro-pollutants and purification sludge at the Vidy purification station, which serves the Lausanne region.

Encouraging external research projects

“The Water and Health seminar co-organised by SUEZ is a forum for the discussion of questions related to water and the possible solutions. The seminar is attended by students and academic and industrial researchers of international renown.”

Sponsoring an annual seminar for PhD students

SUEZ, the University of Lorraine (France) and Bonn University (Germany) co-organise an international Water and Health seminar for PhD students each year. The event provides a forum for students from all over the world to discuss the results of their research, in areas such as pollutants of hydric origin, epidemiology, microbiology and the sociological aspects of crisis management, with leading international scientists. At each seminar, the scientific committee awards the SUEZ Prize to the student whose work makes the best contribution to the improvement of the water sanitation and quality.

Providing a forum for discussion

The seminar provides a forum where students can share their experiences and projects with other young people and encourages dialogue between different generations of scientists and the disciplines related to this issue.

The 2016 SUEZ Water and Health Award

Loïc Voisin, Director of Innovation, Marketing and Industrial Performance, awarded the SUEZ Water and Health Award and a cheque for €1,500 to Caroline Delaire of the University of California in Berkeley, for her thesis: ‘From arsenic and bacteria removal to household behavior change: How to improve access to safe water in West Bengal, India.’

The presentations were judged according to four criteria:

  • The scientific approach
  • Innovation
  • Possible applications to water
  • The quality of oral communication
