→‎Water extraction

====Water extraction====

* Water can be abstracted from the same borehole or well used for injection/recharge – this is called Aquifer Storage Recovery (ASR).

* Water can also be abstracted from a separate borehole or well than the one used for injection/recharge – this is called Aquifer StorageTransfer and Recovery (ASTR). In the case of roof rainwater recharge systems in Mozambique, this design was used where the pump would extract water from a separate place close to the screen connected to the roof catchment.
