Groundwater Injection and Recovery System (GIRS)

Groundwater Injection and Recovery System (GIRS)

Definition

A system installed on the BIP that be used in the unlikely event that the Groundwater Treatment Plant can not operate for an extended period (e.g. three months or more). It entails re-injection of groundwater extracted from secondary containment area in to the aquifer up hydraulic gradient of the BIP extraction line to ensure later recovery of the injected water.
