San Diego Branch Meeting

The San Diego Branch proudly presents a special double feature:

IAH Commission on Managing Aquifer Recharge: An Introduction and Opportunity to Engage

Peter Dillon, Co-Founder, IAH MAR

and a presentation on:

Water Supply Reliability with Aquifer Storage Recovery

David Pyne, President of ASR Systems



This meeting will feature a joint presentation by Peter Dillon, co-founder of IAH Commission on managed aquifer recharge and David Pyne, president of ASR Systems. Mr. Dillon will present his talk titled “IAH Commission on Managing Aquifer Recharge (MAR) –a global rescue mission!” discussing the issues that the Commission is addressing through its working groups. The discussion is encouraged to be interactive and with knowledgeable input regarding key issues facing the advancement of MAR in USA.

Mr. Pyne will present his talk titled “Achieving Water Supply Reliability with Aquifer Storage Recovery.” Mr. Pyne’s talk will discuss how to identify and resolve selected technical issues related to ASR well, wellhead and wellfield design and operation, focusing on practical considerations (considerations such as the target storage volume; recovery efficiency; well clogging and redevelopment; monitor wells and water quality issues) and scientific considerations (such as aquifer hydraulics, mobilization and attenuation of selected water quality constituents, and associated geochemistry). Real-world examples of the wide variety of ASR applications will be presented and recent developments and technical/scientific advances will be discussed.


Mr. Peter Dillon: For 29 years Peter was a researcher with CSIRO in Australia on groundwater protection, water recycling and MAR. Subsequently, he co-founded an IAH Commission on Managing Aquifer Recharge, which he still co-chairs, aiming to maximise the benefits of wise use of MAR. Since 1991 his team’s research on ASR with stormwater and recycled water led to the development of the first, and still only, risk based guidelines for MAR for health and environment protection, adopted in Australia in 2009. They also developed a water allocation framework for MAR consistent with Australian water policy reform. Retired in 2014 he is now an Honorary Fellow of CSIRO, adjunct chair at several universities, and besides the IAH Commission he facilitates change through Australian Water Association, Stormwater Australia, WaterSensitive SA and Brownhill Creek Association, in integrating groundwater understanding and MAR into urban water management. He is active in India on village level groundwater management including MAR.  He also consults in association with Wallbridge Gilbert Aztec.

Mr. David Pyne: President of ASR Systems, is a civil engineer with degrees from Duke University and University of Florida, with PE registration in several states. Mr. Pyne is a pioneer in the development of the Aquifer Storage Recovery (ASR) concept for water storage in wells in fresh, brackish, and seawater aquifers. Mr. Pyne authored the first book published on ASR: Aquifer Storage Recovery:  A Guide to Groundwater Recharge Through Wells, 2nd Edition (2006). He has provided ASR consultant services for California American Water for the Seaside Groundwater Basin, Monterey; Metropolitan Water District of Southern California; Calleguas Municipal Water District; Sonoma County Water Agency; City of Woodland; City of Yuba City; Squaw Valley Public Service District, City of Roseville, and many other clients nationwide and overseas. In addition, he has provided direction or significant technical input during development of ASR wellfields and recharge wellfields for almost half of the approximately 140 such wellfields in the United States, providing seasonal and drought water storage underground to achieve sustainable and reliable water supplies. His work abroad includes technical support for ASR wellfield development in Canada, England, The Netherlands, India, Namibia, South Korea, Kuwait, Saudi Arabia, Qatar, United Arab Emirates, China, Taiwan, St Kitts and other locations in the Caribbean.
