Ruby Ranch Water Supply Corporation (RRWSC) and Barton Springs/Edwards Aquifer Conservation District are cooperating on a project to test the Middle Trinity Aquifer as a reservoir for storage and recovery of fresh Edwards Aquifer groundwater. By injecting fresh Edwards water when there is no drought, RRWSC can have a greater quantity of water available for summer-time usage.
In March 2017, the Texas Commission on Environmental Quality granted permission to conduct an ASR pilot project. The pilot project consists of multi-step tests with increasing volumes of injected water in each successive step predicated upon successful results at each step.
