Bill > SB1210

This bill allows the Commission on Water Resource Management to require dual line water supply systems (parallel water lines for potable and nonpotable water) in new residential and mixed-use developments located in designated water management areas, starting after June 30, 2025. The bill expands existing rules about water infrastructure to include residential developments, whereas previous regulations only covered commercial and industrial projects. The Commission can mandate these dual line systems unless there are concerns about water quality, nonpotable water availability, or potential threats to existing water uses. Additionally, the bill authorizes residential and mixed-use developments to be included in irrigation projects, permits the Board of Agriculture to investigate nonpotable water availability, and requires the Department of Health, Board of Agriculture, and counties to update their rules and ordinances to allow and support dual line water supply systems. The legislation also preempts any existing state or county rules that might prevent the installation of such systems and specifically allows single-family residential home irrigation without requiring a designated recycled water manager. These changes aim to promote more efficient water use and conservation by enabling the use of nonpotable water for purposes like irrigation in new developments.
