S.B. No. 616 amends the Water Code to regulate aquifer storage and recovery (ASR) projects that intersect the Edwards Aquifer. The bill specifies that the Texas Commission on Environmental Quality (TCEQ) may authorize injection wells that transect the Edwards Aquifer under certain conditions. These conditions include the injection of groundwater withdrawn from the Edwards Aquifer, storm water, flood water, or groundwater through improved sinkholes or caves in karst areas, and the injection of water into a geologic formation underlying the Edwards Aquifer for ASR projects. Notably, the bill identifies specific areas in Williamson County and Medina County where these ASR injection wells may be permitted.

Additionally, the bill mandates that the TCEQ adopt rules to implement these changes by March 1, 2026. The act will take effect immediately if it receives a two-thirds majority vote from both houses; otherwise, it will take effect on September 1, 2025. This legislation aims to enhance the management and sustainability of water resources in Texas, particularly concerning the Edwards Aquifer.
