About the Conference


The 2014 NWRI Clarke Prize Conference brought together scientists and experts from across the water community to discuss the most innovative research and technology developments happening today in urban water sustainability.


Held on November 7, 2014, in Huntington Beach, California, the conference featured presentations by the NWRI Clarke Prize Laureates, representatives from local water and wastewater utilities, and academics from the US and abroad. The talks focused on managing and advancing sustainable water treatment technologies.


The result was an extended discussion on water resources that included theoretical concepts, basic science research, practical applications, and case studies. The highlight of the event was the Clarke Prize Award Ceremony and Lecture in honor of David L. Sedlak, Ph.D., Professor of Civil and Environmental Engineering at University of California, Berkeley, and the twenty-first recipient of the NWRI Athalie Richardson Irvine Clarke Prize for excellence in water research.


Sedlak received the Clarke Prize medallion and a $50,000 cash award in recognition of his pioneering research on how urban water infrastructure is managed. His advances have included implementing water reuse and reducing the discharge of emerging contaminants such as pharaceuticals and personal care products. Sedlak's work has served as the foundation for major policy and technical initiatives to reduce the effects of these contaminants and protect public health.


More than 140 people attended the conference, representing universities, consulting firms, government agencies, manufacturing firms, water and wastewater utilities, and others.
