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

HB 1618 modifies Texas Water Code to allow specific aquifer storage and recovery (ASR) projects in Williamson County east of Interstate 35 that transect the Edwards Aquifer. It permits these projects - where water is injected into underlying geologic formations - as an exception to the general ban on injection wells in the aquifer. The Texas Commission on Environmental Quality must adopt implementing rules by March 1, 2026. The bill affects water project developers and regulators in the specified Williamson County area, with implementation dependent on legislative approval for immediate effect or set to take effect September 1, 2025.
