HB 2817 seeks to amend existing law governing the use of water withdrawn from the Edwards Aquifer. The bill stipulates that water drawn from the aquifer must be used either within the boundaries of the Edwards Aquifer Authority or within the certificated area of a retail public utility, as defined by a certificate of convenience and necessity existing as of September 1, 2025. This measure ensures that water resources are utilized within the intended jurisdictional areas and prevents the unauthorized transfer of water outside the defined regions.
