The 2013 NWRI Clarke Prize Conference brought together leading scientists and experts from all across the water community to discuss the most innovative research and technology developments happening today in urban water sustainability.


Held on November 15, 2013, in Newport Beach, Calif., the conference featured presentations by the NWRI Clarke Prize Laureates, representatives from local water and wastewater utilities, and academic researchers that focused on planning, managing, and advancing treatment technologies for sustainable water supplies and resources.


The result was a broad mix of talks on theoretical concepts, fundamental research, practical application, useful experience,

and real-world challenges and needs.


The highlight of the event was the Clarke Prize Award Ceremony and Lecture, where we celebrated the Twentieth Anniversary of the Clarke Prize and honored civil and environmental engineer Dr. R. Rhodes Trussell of Trussell Technologies, Inc., as the 2013 recipient of the NWRI Athalie Richardson Irvine Clarke Prize for excellence in water research.


Trussell received the Clarke Prize because of his extraordinary accomplishments in using fundamental scientific principles and current research findings to solve the most challenging water quality problems and improve the designs of new water treatment plants and technologies. The Clarke Prize consists of $50,000 and a medallion.


Over 180 people attended the conference, representing universities, consulting agencies, government agencies, manufacturing firms, water and wastewater utilities, and others.
