California Assembly advances SB 31 to expand recycled water usage

The Assembly Water, Parks, and Wildlife Committee convened on June 17, 2025, to discuss Senate Bill 31, which aims to expand the use of recycled water in California. With projections indicating a potential 10% decrease in the state's water supply over the next decade, the bill is seen as a crucial step towards addressing water scarcity.

Senator introduced SB 31, highlighting its focus on allowing tertiary treated recycled water for various applications, including decorative landscaping, golf courses, and even certain food handling scenarios, provided strict safety measures are followed. The senator emphasized that while the bill represents a modest change, it is a necessary move in the right direction, especially given the lack of opposition and strong support from stakeholders.

Beth Olaso, representing Water East California, elaborated on the bill's provisions, which include allowing recycled water for toilet flushing in food processing facilities and irrigation in parks, ensuring that no watering occurs when the areas are in use. The bill also seeks to clarify regulations regarding when recycled water is classified as sewage, aiming to improve public perception and reduce penalties associated with water line breaks.

Additionally, SB 31 proposes easing requirements for homeowners' associations using recycled water for common area irrigation, eliminating the need for dual plumbing systems, which can be costly and complex.

The committee's discussions reflect a growing recognition of the importance of sustainable water management practices in California, as the state grapples with ongoing water supply challenges. The next steps will involve further refinement of the bill as it moves through the legislative process, with an eye toward enhancing water conservation efforts and ensuring community safety.
