Who ever claimed that Californians were full of trash?
Golden State officials this week approved new “toilet-to-tap” regulations, allowing water agencies to take wastewater from homes, recycle it and pump it back into homes in an effort to boost the nation’s dwindling water supply. state.
“When completed, it will truly be the highest quality water delivered in the state,” said Darrin Polhemus, director of the Division of Drinking Water and the State Water Resources Control Board.
Despite some consumer concern, officials have guaranteed the plan is safe because the wastewater undergoes three rigorous stages of treatment.
The water is treated for pathogens and viruses so thoroughly that officials say minerals need to be added back to improve the taste.
“If one fails, there are still two in place as a backup to ensure nothing is left untreated,” Polhemus said.

California is notoriously drought-prone and relies on water from other states through the Colorado River.
However, 2023 brought an exceptional amount of rain, and by October, the state was more than 99% drought-free, according to the Los Angeles Times.
Although the water will be more expensive than imported water, the supply is more renewable and reliable, according to CalMatters.
California is the second state to allow the process, after Colorado.

California has been using recycled water for decades to grow vegetable and fruit crops and to water lawns, but this would be the first time the technology would be used directly for drinking water.
“I wouldn’t hesitate to drink this water my entire life,” said Daniel McCurry, an assistant professor of civil and environmental engineering at the University of Southern California.
Since building treatment facilities is expensive and will take a long time, larger cities like San Diego and Silicon Valley/Bay Area that have the funding will be among the first to make the transition.

That means nearly half of San Diego’s supply will be recycled water by 2035, officials said.
“Drought happens all the time and with climate change it will only get worse,” Kirsten Struve of the Santa Clara Valley Water District told ABC. “This is a drought-resistant supply that we will need in the future to meet the demands of our communities.”
