Water is injected into aquifers to provide temporary storage or ongoing replenishment in a number of scenarios: 

• Aquifer storage and recovery (ASR); injection of water into aquifers for storage and future extraction
• Discharge of water that has been cooled by heat exchange processes in geothermal applications
• Recharge of benign wastewater from industrial or mineral processing or mine dewatering

The major limiting factor in the success of aquifer recharge projects is clogging of the injection bore, either through suspended solids, air entrainment, biological fouling and/or chemical reactions.  Rockwater personnel are experienced in assessing, identifying and implementing preventative and remedial procedures required to minimise the risk of clogging.
