Managed aquifer recharge (MAR) is the intentional recharge of water to aquifers for later recovery or environmental benefit. As a water resources management strategy, managed aquifer recharge helps increase groundwater storage, improve water supply reliability, and support ecosystems. It is becoming increasingly important as communities face growing water demands and climate-related challenges, while also providing benefits such as flood risk reduction, stormwater management, subsidence mitigation, and saltwater intrusion control.
The Managed Aquifer Recharge (MAR, 2023) guidance provides a basic understanding of managed aquifer recharge and its applications by presenting a model of the process with the four key components and their interaction. The guidance document discusses the role of managed aquifer recharge in addressing climate change impacts by promoting sustainability and resilience in water resources management. It describes the key components, outlines critical design considerations for each component, and includes case studies that demonstrate a variety of MAR applications.
