Relating to the authority of the Texas Water Development Board to provide financial assistance to certain counties for brackish water desalination.

SB 2123 expands the Texas Water Development Board's authority to provide financial assistance for brackish water desalination projects to specific large border counties. It directly affects counties with populations over 250,000 located on an international border and wholly or partly within a groundwater management area that lacks an existing groundwater conservation district inside the county. The bill adds this funding mechanism to the Water Code, requiring counties to meet both population and groundwater management area criteria. This policy change takes effect September 1, 2025, aiming to support water infrastructure in eligible border regions.
