In a groundbreaking move to address water scarcity and enhance sustainability, California regulators have approved rules allowing water agencies to recycle wastewater for use in the state’s drinking water supply.
This significant development marks a shift in public opinion on recycled water, reflecting California’s ongoing struggle to secure reliable sources of drinking water for its substantial population.
Shift in Water Management
The rules allow treated wastewater to enter the pipes that deliver drinking water to homes, schools, and businesses, making California the second state, after Colorado, to permit such initiatives.
California has faced numerous challenges related to water availability, including prolonged droughts and dangerously low reservoir levels. The state’s more than 39 million residents have witnessed the impact of these water shortages, prompting a reevaluation of water management practices.
The recent approval of rules allowing wastewater recycling for drinking water signals a progressive step toward addressing these challenges and ensuring a more sustainable water future.
While direct use of recycled wastewater for drinking water is a new development, California has a history of utilizing recycled water for various purposes.
Past initiatives have seen recycled wastewater used for ice rinks, snow production at ski resorts, and irrigation of farmland in the central valley, a major agricultural region.
Orange County’s water-purification system has been recycling wastewater for years, replenishing underground aquifers before it is used for drinking water.
The newly approved rules mandate rigorous treatment processes for wastewater, including the removal of all pathogens and viruses, even if not present in the initial wastewater.
This level of treatment ensures that the recycled water meets the same quality standards as regular drinking water, if not better, according to Darrin Polhemus, the deputy director of the division of drinking water for the California water resources control board.
However, the process removes minerals that contribute to the taste of fresh water, necessitating their addition back at the end of the treatment process.

California’s Water Revolution: Recycled Plants Tackle Rising Demand
Implementing wastewater recycling for drinking water involves significant costs and time, making it a viable option primarily for larger, well-funded cities initially.
Water agencies in California, including the metropolitan water district of southern California and projects in San Diego, are already planning substantial water-recycling plants to meet the growing demand for water.
Educating the public about the safety and efficacy of recycled water is crucial, and some agencies, like San José’s Silicon Valley Advanced Water Purification Center, are offering public tours to showcase the high-tech processes involved.
California’s approval of rules allowing wastewater recycling for drinking water marks a pivotal moment in the state’s ongoing efforts to address water scarcity and enhance water sustainability.
By embracing innovative solutions, such as recycled water, California is taking significant steps toward ensuring a reliable and resilient water supply for its residents in the face of climate change and ongoing drought challenges.
