Decentralized Water Reclamation Engineering

Dr. Robert L. Siegrist is University Professor Emeritus of Environmental Science and Engineering at the Colorado School of Mines (CSM) where he is also a Professor of Civil and Environmental Engineering. He earned his BS (High Honors) and MS degrees in Civil Engineering and his PhD degree in Environmental Engineering at the University of Wisconsin. While at the University of Wisconsin, Dr. Siegrist was a graduate student and research staff member with the Small Scale Waste Management Project, a large multidisciplinary research program focused on small systems for water and wastewater treatment and disposal/reuse. Before joining CSM in 1995, Dr. Siegrist held academic and research positions with the University of Wisconsin, Norwegian Institute for Georesources and Pollution Research, and Oak Ridge National Laboratory. Dr. Siegrist was also a founding partner and senior engineer with RSE Inc., an environmental consulting company that specialized in the engineering of decentralized systems for water and sanitation.Dr. Siegrist served as Program Director for the Small Flows Program, which he established at CSM in 1998 to advance the science and engineering of sustainable decentralized approaches to water and sanitation. The Program was designed to enhance the quantitative understanding of processes important to system design and performance and to develop decision-support tools for applications involving individual houses and buildings up to those involving large developments, communities, and watershed-scale situations. To support research and teaching, a unique field test facility, the Mines Park Test Site, was established on the CSM campus. Dr. Siegrist is also developer of an undergraduate/graduate course covering the principles and practices of decentralized water reclamation and reuse, which he has taught for the past 10 years.  Dr. Siegrist is an internationally recognized expert in decentralized systems for wastewater treatment and water reclamation as well as remediation of contaminated soil and groundwater.  He has published over 300 technical papers, 7 book chapters, and 2 textbooks. Dr. Siegrist has given invited lectures at more than 100 workshops and conferences in more than 30 countries worldwide. He was a founding Member of the Consortium of Institutes for Decentralized Wastewater Treatment, a group of 25 educational institutions cooperating on training and research efforts in the area of decentralized wastewater treatment and water reclamation. During his career Dr. Siegrist has served as a science and engineering advisor to numerous U.S. and foreign companies, organizations and agencies and has been a Fellow with the NATO Committee for Challenges to Modern Society.
