Bill Summary · SB 31

Legislative bill overview

SB 31 updates California's water quality standards and regulatory framework for recycled water use. The bill expands pathways for treating and distributing recycled water for non-potable applications like irrigation, toilet flushing, and industrial processes. It streamlines permitting processes while establishing safety protocols to protect public health and water quality.

Why is this important

California faces chronic water scarcity exacerbated by drought and population growth, making alternative water sources critical infrastructure. Recycled water can offset demand on stressed groundwater and surface supplies, but regulatory barriers have limited its adoption. This bill removes obstacles to scaling recycled water infrastructure, potentially reducing pressure on traditional water supplies while creating economic opportunities in water treatment technology.

Potential points of contention

  • Implementation costs: Water agencies and municipalities may face significant expenses upgrading infrastructure and treatment facilities to meet new standards, potentially raising customer water rates
  • Public health concerns: Some residents and advocacy groups may resist direct use of recycled water without confidence in safety testing and long-term health impact studies
  • Equity in access: Rural and smaller water districts may struggle to afford compliance infrastructure, creating geographic disparities in recycled water availability and potentially widening water access inequality
