Relating to aquifer storage and recovery projects that transect a portion of the Edwards Aquifer.

HB 4931 modifies Texas water law to allow certain aquifer storage and recovery (ASR) projects that cross through the Edwards Aquifer, specifically authorizing ASR injection wells in Medina County for water storage. It permits these projects under a new exception to a general rule banning most injection wells in the Edwards Aquifer, while maintaining restrictions on other types of injections. The bill requires the Texas Commission on Environmental Quality to adopt implementing rules by March 1, 2026. This change directly affects water management projects in Medina County seeking to store water underground in the Edwards Aquifer formation.
