Managed aquifer recharge (MAR), also known as water banking, consists of water management techniques, methods and policy – using treated or non-treated water to recharge an aquifer, and/or surface or subsurface (i.e., via wells)  recharge methods. Surface water recharge methods include spreading basins, stormwater harvesting, and diversions to river channels during low flow seasons. Well recharge methods or aquifer storage and recovery (ASR) use either single purpose (injection) wells and separate extraction wells, or dual purpose wells that can both inject and extract stored or banked groundwater as needed.

Recent legislative actions in California have moved the State towards a comprehensive policy regarding groundwater management. These new regulations and laws will have particular impact on groundwater basins that have been defined by the California Department of Water Resources as medium or high priority basins. The legislation, signed into law in 2014, creates a framework for sustainable, local groundwater management and allows local agencies to modify sustainable groundwater plans to their regional needs.

This presentation will discuss MAR site development, various recharge strategies that can be used in a MAR system, operational and maintenance considerations of a system, engineering and geologic considerations, site conceptual modeling, asset management, public outreach, and regulatory requirements.
