Managed Aquifer Recharge (MAR) is the intentional recharge of an aquifer under controlled conditions for subsequent recovery, environmental benefit, or to mitigate the impacts of abstraction. The managed process assures adequate protection of human health and the environment.

There are a number of methods used to recharge aquifers, including injection wells or infiltration structures such as ponds, basins, galleries and trenches. These methods help to reduce transport and storage costs and water loss through evaporation.

Water from a variety of sources can be used in the recharge process. These include water from subsoil groundwater, stormwater and treated wastewater.

Natural treatment processes in the aquifer can improve water quality. Some pre-treatment of the source water may be required to make sure that the quality of the receiving groundwater is maintained or improved.

The level of treatment needed for the source water generally depends on a risk assessment. (DWER website, 2017)
