Technical Resources

Regulations, Guidelines, and Legislation

  • California: In September 2018, California signed into law Senate Bill 966, which directs the State Water Resources Control Board to establish risk-based water quality standards for onsite non-potable water systems. The SFPUC collaborated with Senator Scott Wiener to develop the legislation. The work that’s been accomplished to date by the National Blue Ribbon Commission will support the state’s development of the risk-based water quality standards.
  • Colorado: In August 2018, Colorado Department of Public Health and Environment updated Regulation #84, which regulates reclaimed water use, to allow localized nonpotable water systems to treat onsite wastewater for toilet flushing and irrigation. Colorado adopted a risk-based water quality approach for localized water reuse systems.
  • Hawaii: Hawaii passed legislation House Bill 444 in 2019 directing the Hawaii Department of Health to adopt a localized set of rules for onsite non-potable water systems with guidance from the National Blue Ribbon Commission.
  • Minnesota: Minnesota Department of Public Health has moved forward with guidance for onsite non-potable water systems. A report was published in March 2018 Advancing Safe and Sustainable Water Reuse in Minnesota. Recommendations from Minnesota’s report include adopting the risk-based water quality approach.
  • Washington: In 2021, House Bill 1184 was passed and signed into law. The legislation directs the Washington Department of Health to develop state-wide risk-based water quality standards for the use of onsite non-potable water reuse systems in commercial and multi-family buildings
