Aquifer Storage Recovery Wells, Recharge Wells and Wellfields:  Design, Equipping and Operation


ASR wells and recharge wells are quite different from standard water supply wells. Successful and sustainable recharge via wells requires a collaborative effort by scientists and engineers from across multiple disciplines.  Failure of some MAR systems can be attributed directly to poor design of the recharge wells, inadequate characterization of the source and receiving water, poor engineering design of the well equipping or wellhead facilities, or miscommunication concerning the primary objective of the MAR system. 

This workshop will guide participants through the pre-requisites for, and technical feasibility of ASR systems for a variety of water sources, aquifer types, and end uses. The focus of the workshop will be on the key technical issues associated with planning, feasibility, design, construction, and performance evaluation of recharge and recovery systems via wells. Case studies will be used to illustrate the key technical issues, performance and scientific considerations that need to be employed to deliver successful, integrated and sustainable ASR operations. 

The workshop is aimed at MAR practitioners across all experience levels (Basic, Intermediate or Advanced). Some prior knowledge of MAR techniques and terminology is useful but not essential to attend this workshop. 

Topic Covered 

Supported by selected case studies illustrating the technical and scientific issues of ASR, the key points to be covered during this workshop include, in the following approximate order:

  • Technical considerations for ASR well, wellhead and wellfield design and operation.
  • ASR applications, plus recent developments and technical / scientific advances.
  • A recommended approach to ASR project development to achieve success.
  • Recovery efficiency and well clogging remediation approaches.
  • Aquifer characterization and understanding scientific considerations such as aquifer hydraulics, water quality issues, and geochemistry.
  • Achieving water supply reliability and sustainability using ASR as an integrated water resources management tool. 
  • Legal and regulatory frameworks for ASR.
  • ASR economic considerations.


David Pyne has presented ASR workshops since 1994, ranging from one-hour to two days’ duration, throughout the USA and at several ISMAR symposia in other countries.  Sponsoring organizations have also included ASCE, NGWA and World Bank.  Co-presenters have included Dr Herman Bouwer, Dr Daniel Stephens, Russell Martin and Tom Morris.  David is a professional civil engineer.  He pioneered the development of Aquifer Storage Recovery technology and has directed or contributed significantly to the development of many ASR wells and wellfields globally.  


State of the Art Techniques in Identifying and Characterizing Optimum Surface Spreading Groundwater Recharge Projects


Successful site selection and design of surface spreading groundwater recharge operations are highly dependent on subsurface geologic conditions, source water quality, land availability and nearby land use.  This course is designed to present, discuss and evaluate the best tools for site evaluation and subsurface characterization and the application of these tools for feasibility studies and recharge system design.  A brief overview of modeling and monitoring tools will also be presented.  A spectrum of case studies will be presented to illustrate the application of these tools and interpretation of data.  Specific topics to be covered include:    

  • Defining recharge site goals and criteria for selecting an optimum recharge site
  • Phased approaches to site characterization and site selection
  • Near-surface field methods for hydraulic characterization
  • Deep sub-surface field methods for hydraulic characterization and monitoring
  • Modeling of recharge basin performance
  • Integration of characterization, monitoring and modeling
  • Considerations and methods for maintaining optimum operations

Course Objectives

The objective of the course is to provide participants with knowledge of the best tools and exposure to real-life conditions to ensure success in siting, characterizing, designing and monitoring surface spreading groundwater recharge operations. 


Who Should Attend

The course is designed for consulting and government scientists, engineers and managers who are or will be involved in groundwater recharge studies and operations.  A background in the physical sciences or engineering is desirable.  


Mike Milczarek has over 25 years of experience in developing, implementing, and managing vadose zone, hydrogeologic and geochemical studies.  Groundwater recharge experience ranges from managing or participating in 40 groundwater recharge feasibility studies, evaluating and modeling recharge in riparian habitat restoration areas and designing and implementing investigations on stormwater capture and enhanced recharge.  He graduated with Bachelors’ degrees in Chemistry and Environmental Science from Northern Arizona University and a Master’s degree in Soil and Water Science from the University of Arizona.

Adam Hutchinson is the Recharge Planning Manager for the Orange County Water District in southern California.  He has over 25 years water resources experience.  In his 17 years at the District, he has worked as Director of Recharge Operations and as Senior Hydrogeologist.  He has an undergraduate degree in Geology, and a master’s degree in Hydrology from the University of Arizona. He is a Professional Geologist (PG) and Certified Hydrogeologist (CHG) in the state of California.
