The California Water Efficiency Partnership (CalWEP) has submitted a letter of support for Senate Bill 597 (Glazer), legislation that aims to explore and establish building standards for rainwater catchment systems in new residential construction. By requiring the Department of Housing and Community Development to review current practices, conduct research, and develop recommendations, SB 597 takes a proactive approach to enhancing water efficiency and conservation in California.

Why Rainwater Catchment Systems Matter
As California faces increasing water challenges due to climate change, innovative solutions like rainwater catchment systems are essential for promoting water conservation and bolstering local water supply resiliency. These systems collect rainwater for nonpotable uses, such as landscape irrigation, reducing reliance on traditional water supplies and making better use of the state’s often unpredictable precipitation.
With atmospheric rivers becoming more common alongside periods of drought, these systems offer a practical and effective way to capture and utilize water that might otherwise be lost. SB 597 supports this approach by laying the groundwork for the adoption of consistent standards, ensuring safe and efficient implementation statewide.
The Role of SB 597
SB 597 tasks the Department of Housing and Community Development with conducting research and developing recommendations on building standards for rainwater catchment systems. These recommendations could then be proposed to the California Building Standards Commission for formal consideration, paving the way for greater integration of rainwater systems into new residential developments.
By addressing this issue at the state level, SB 597 helps create a foundation for water conservation that benefits both communities and the environment. This step aligns with CalWEP’s mission to support innovative technologies and effective public policies that maximize water efficiency throughout California.
Looking Ahead
CalWEP applauds Senator Glazer for his leadership on this important issue and supports the effort to establish practical, research-based standards for rainwater catchment systems. This forward-thinking legislation will help California communities adapt to changing water conditions while promoting sustainable practices.
