WaterAid today congratulated the winners of the prestigious 2018 Stockholm Water Prize, Prof. Bruce E. Rittmann and Professor Mark van Loosdrecht.

In awarding the prize, the water institute SIWI said the two professors had, by revolutionizing microbiological-based technologies in water and wastewater treatment, demonstrated the possibilities to remove harmful contaminants from water, cut wastewater treatment costs, reduce energy consumption, and recover chemicals and nutrients for recycling.

Their pioneering research and innovations have led to a new generation of energy-efficient water treatment processes that can effectively extract nutrients and other chemicals – both valuable and harmful – from wastewater, SIWI said.

Mark van Loosdrecht is Professor in Environmental Biotechnology at Delft University of Technology, The Netherlands. Bruce Rittmann is Regents’ Professor of Environmental Engineering and Director of the Biodesign Swette Center for Environmental Biotechnology at the Biodesign Institute, Arizona State University, USA.

WaterAid Chief Executive Tim Wainwright said:

"Innovations like those developed by Professors Rittmann and van Loosdrecht are essential if we are to reach the UN Global Goal to deliver water and sanitation to everyone, everywhere by 2030. In an increasingly water-stressed world, applying technology to remove contaminants and recycle nutrients has an important role in securing our water resources.

"With 844 million people in the world still without basic access to clean water close to home, and 60% of the world living in areas of water stress where water cannot or will not continue to meet demand, it is more essential than ever that nongovernmental organisations, governments, academia and the private sector work together to change the current course and take urgent action.

"On this World Water Day, we thank Professors Rittmann and van Loosdrecht for their dedication, and congratulate them on their award."

WaterAid received the Stockholm Water Prize in 1995.

Notes to Editors:

WaterAid’s vision is of a world where everyone has access to clean water and sanitation. The international not-for-profit organisation works in 34 countries to change the lives of the poorest and most marginalised people. Since 1981, WaterAid has reached 25.8 million people with clean water and 25.1 million people with decent toilets.

  • 844 million people in the world – one in nine – do not have clean water close to home.[1]

  • 2.3 billion people in the world – almost one in three – do not have a decent toilet of their own.[2]

  • Around 289,000 children under five die every year from diarrhoeal diseases caused by poor water and sanitation. That's almost 800 children a day, or one child every two minutes.[3]

  • Every £1 invested in water and toilets returns an average of £4 in increased productivity.[4]

  • Just £24 can provide one person with clean water.[5]
