The Brief

The California State Water Resources Control Board on Tuesday approved new regulations for direct potable reuse, AKA "toilet to tap," or highly treated sewage that’s piped directly from a water treatment plant to your home.

Some of the largest direct reuse programs in the state are being developed here in Southern California.

So, when will you be able to gulp down water that’s gone from flush to faucet?

A bit of background

While this might sound like a new development, these regulations have been in the works for more than a decade now. And whether you realize it, there’s a decent chance you’ve already been drinking small amounts of purified sewage water in California.

Indirect potable reuse has been allowed for quite some time. That’s when sewage water is treated, pumped into a reservoir or some other environmental buffer, mixed with natural sources of water and then pumped back out and treated again.

Orange County has had one of these recycled water systems in place since 2008.

“The reality is that anyone out there on the Mississippi River, anyone out there on the Colorado River, anyone out there taking drinking water downstream from a wastewater treatment plant discharge, which I promise you you’re all doing, is already drinking toilet to tap,” said E. Joaquin Esquivel, chair of the California State Water Resources Control Board, during the meeting Tuesday.

Recycled water programs have been ongoing since the 1980s, with the finished product frequently used to irrigate places like golf courses and public parks.

Our water problems have been getting worse each year as a result of higher temperatures and extreme drought conditions exacerbated by the climate crisis. We need to explore alternatives to imported water, which is why recycling is a key part of the state’s water supply strategy.

In the near future, toilet to tap could account for as much as 10% to 15% of our supply, according to Darrin Polhemus, deputy director of the division of drinking water for the California State Water Resources Control Board.

Up to 90% of contaminated water streams can be reliably recycled, with the leftover discharge usually sent to the ocean.

The new regulations aren’t the final word on direct potable reuse. Guidance will continue to develop as systems are implemented. And there’s no requirement for localities to participate in wastewater reuse. Any projects that do go ahead should be open for public comment before they’re approved.

Is it safe?

“I would have no hesitation drinking the first glass out of the first potable reuse facility in California,” said Daniel McCurry, assistant professor of civil and environmental engineering at USC. “I think it’s going to be cleaner than most bottled water you could find.”

The new rules require a minimum of four separate treatment processes, ensuring redundancies in case one fails. And the process is monitored from beginning to end. If the water doesn’t pass the necessary requirements, it’s discarded.

Reverse osmosis, UV lights and carbon filters are all part of the filtration process. Helping to pull out and eliminate everything from pharmaceuticals to PFAS, to enteric viruses and protozoa like giardia and cryptosporidium, all of which can cause serious gastrointestinal issues — 99.999999999999999999% (that’s 18 nines after the decimal point) have to be removed. That's a higher degree of purification than is required for indirect potable reuse, which has been in place.

“These are probably the most protective potable reuse regulations that’ve ever been written,” McCurry said. “There’s probably some in the industry who feel like they're too strict, but it’s probably wise for us to err on the side of caution for now.”

City of L.A.

L.A.’s recycled water program is called Operation NEXT, the goal of which is to retrofit the Hyperion wastewater treatment plant so that instead of sending our treated water out into the ocean, we can pump it back into storage systems, including the aquifer beneath the San Fernando Valley.

“It’ll create a new drinking water supply for the city of L.A. leading to sustainability and the development of local supplies. All the things that we know we need here, specifically in Los Angeles, given the climate crisis," said Jesus Gonzalez, manager of recycled water at LADWP.

Besides a retrofit to purification technologies, L.A. will also have to build pipelines all of the way from Hyperion to conveyance facilities.

Gonzalez anticipates that the $20 billion investment should supply roughly a third of the city’s future water supply. That said, it could take another 15-plus years before it’s up and running.

Los Angeles County

L.A. County is partnering with the Metropolitan Water District on a program called Pure Water Southern California, which could be the largest facility of its type in the United States, according Deven Upadhyay, executive officer at the MWD.

They’re currently in the environmental planning stage, and the cost estimate for the first phase of the program is going to be about $6 billion.

“That’s a lot of money in the water world,” Upadhyay said.

We’ll have to wait and see how the new regulations are used, but at least some of the water will be pumped into groundwater basins for storage. Upadhyay didn’t specify how much of our water could be covered by the new system.

Orange County

Orange County has the world’s largest water recycling plant, and has been running their indirect potable reuse program since 2008.

They currently produce about 130 million gallons of recycled water every day, processing all of the available wastewater across the O.C. Sanitation District.

About 40% of what’s put back into the aquifer is coming from their O.C. treatment facility.

“We’re recycling everything we can recycle in terms of taking the treated wastewater, putting it through advanced treatment to a point where it’s beyond drinking water quality, and then putting it back into the underground aquifer,” said Mehul Patel, executive director of operations for the O.C. Water District.

Patel doesn’t anticipate these new regulations will affect the current system they have in place.

However, he said there’s a possibility that O.C. could see changes as a result of the regulations south of Irvine, where they don’t have a lot of naturally occurring water storage areas, leaving them reliant on imported water. They may benefit from a direct potable reuse plant there, though nothing is planned at the moment.

San Diego

By 2035, San Diego wants recycled water to account for half of their supply. Currently, they recycle about 8% of their wastewater, sending the rest out to the Pacific Ocean.

Phase 1 of their Pure Water San Diego project is currently under construction, and is expected to be completed by 2026, providing as much as 30 million gallons of recycled water a day. That water is slated to be sent to the Miramar Reservoir, where it’ll be mixed with other water in the system.

There are no current plans for San Diego to implement direct potable reuse, according to a statement from city spokesperson Ramon Galindo. That could change with Phase 2 of the project.

Republican Sonja Shaw conceded the race for California Superintendent of Public Instruction to Democrat Richard Barrera late Wednesday evening.

“Last night voters made their choice. I would be lying if I said my heart wasn’t heavy,” Shaw said in a statement shared on social media. “As a mother and a protector of children, I feel deeply saddened for the kids. They are the ones who deserve so much better.”

In her social media post, which included a photo of Shaw locking hands with her husband and two daughters, Shaw said her kids had motivated her to run for state superintendent. Shaw won election to the Chino Valley Unified school board in 2022, fueled by support from conservative parents.

“The problem is that for decades, the same people have had their hands on our education system while our children have continued to fall behind,” Shaw said. “I believe we had an opportunity to change that.”

The office of California superintendent of public instruction is nonpartisan, with no party affiliation listed on the ballot. In past races, it was not unusual for two Democrats to advance to the November election. But this year, endorsements, campaign funding and campaigning broke largely along partisan lines.

Shaw, a Republican and board president of Chino Valley Unified, emerged as the top vote getter in a crowded June primary that featured several Democratic state lawmakers. But she contended in her statement that her race didn’t have the “money or machinery” that her opponent did in the November election.

Shaw trailed Barrera by nearly 15 percentage points, according to the latest election results Thursday morning. Shaw’s campaign raised about $595,000 compared to Barrera’s $812,000. However, the California Teachers Association, the state’s largest teachers union and a heavy spender in state superintendent races, also spent $8.4 million to support Barrera, the board president of San Diego Unified.

That pales in comparison to the combined $50 million raised in the 2018 state superintendent race Tony Thurmond won against Marshall Tuck in 2018. The 2026 state superintendent race had the distinction of featuring two local school board members.

Shaw said she’s not sure what her next steps will be.

“I don’t know exactly what God has next, but I know He isn’t finished,” she said.

Shaw will not be returning to the Chino Valley Unified school board where she began her political career. Her husband, Chris Shaw, ran for her open seat and is trailing his challenger by 11 points, according to the San Bernardino County Register of Voters.

The Wallis Annenberg Wildlife Crossing over the 101 Freeway in Agoura Hills is set to officially open next month, but that hasn’t stopped some wildlife from already using it.

Cameras captured coyote footage twice — once last week and again on Thursday morning — making the mammal the first large animal species seen using the crossing.

“This is amazing — obviously, the wildlife are not waiting for our opening date,” said Beth Pratt, president of the Wildlife Crossing Fund. “The animals are already blessing this crossing and saying, ‘Yep, you got it right.’”

Construction of the expansive bridge began in 2022, aimed at giving wildlife safe passage between the Santa Monica Mountains and Simi Hills after years of research.

Pratt said it’s unclear whether the images of the coyote are of the same animal. The coyote in the most recent image from Thursday morning can be seen on the 101 structure holding a bone or a stick in its mouth.

“The coyote is validating that we got this designed right, and I think that there's something also about a coyote being first — kind of the L.A. mascot next to P-22,” Pratt said.

The National Park Service is installing more cameras along the crossing to document and study how animals use it. While images will be made publicly available, there will not be a livestream.

“We can't, for security reasons, because this is L.A., and if there's a mountain lion going across, somebody's gonna go try to pet it,” Pratt said.

Topline:

• How we got here: Roy held on to a strong lead over McKinney ever since polls closed and is currently ahead by more than twice as many votes. Roy will be a fresh face to the role after the incumbent city attorney, Hydee Feldstein Soto, was ousted in the June primary in a rare defeat of an elected city official. 

• What the candidates had to say: 
  
  • Roy said on social media Wednesday that election night was “a really good night for the people who believe that we should take care of one another, that we can stand up for our rights — even in what feels like an increasingly lawless world — and that we will achieve justice when we fight for it.”
  • McKinney posted on social media Thursday that he’s back in his old office at the Hall of Justice. “The run for City Attorney was an incredible journey, and I’m truly grateful for everyone who believed in me, supported me, and stood by my side,” McKinney wrote. "While I’m disappointed things didn’t turn out the way we hoped, I wouldn’t trade the experience for anything." He acknowledged Roy in a social media video earlier this week, describing her as a “hard worker” who put together a strong coalition of support. McKinney added that he would be “rooting for her.”
  • Neither campaign immediately responded to LAist’s requests for additional comment.
• What’s at stake: The city attorney runs an office of more than 550 lawyers representing L.A. in all legal matters, including filing lawsuits and defending against them. Roy, backed by powerful progressives like U.S. Sen. Bernie Sanders, has vowed to take on the Trump administration in court.
• Go deeper: Read more about the city attorney's role and what's on the table for Roy's first term.

Construction of the green metal fence around MacArthur Park will begin Monday, Nov. 16, with work scheduled to continue through fall 2027.

The city announced the start date Nov. 4, saying crews will install an 8-foot fence around the park’s perimeter. Nearby residents and businesses can expect some noise, dust and vibration during construction, although the city said mitigation measures will be in place.

Crews will work Monday through Friday from 7 a.m. to 3:30 p.m., and the park will remain open while crews are working. 

The fence is the city’s latest attempt to tackle longstanding problems at MacArthur Park, including drug use, homelessness and crime.

The city first approved plans for the fence in October 2025, and the proposal has since drawn both support and criticism from residents and community groups.

Some say they hope the fence will make the park safer, while others question whether it will actually improve conditions there. Police and city officials say the fence will give them more control over the space and make it easier to enforce the law.

Ana Luz Vazquez, a street vendor near MacArthur Park, said her main concern about the fence is what will happen to the unhoused people who stay in the park throughout the day and whether the city plans to address that issue directly.

She is also concerned that construction during the day could affect her ability to work because of traffic, less parking availability and loud noise.

Vazquez said she would prefer construction to take place at night so it would have less of an impact on street vendors.

“If they’re working in the day then how are we supposed to come here and who is going to help us survive,” Vazquez said.

Construction will happen in two phases

Phase 1

• Alvarado St. from W. 6th St. to Wilshire Blvd.
• S. Park View St. from Wilshire Blvd. to W. 6th St.
• Wilshire Blvd. from Alvarado St. to S. Park View St.

Phase 2

• Alvarado St. from Wilshire Blvd. to W. 7th St.
• S. Park View St. from W. 7th St. to Wilshire Blvd.
• Wilshire Blvd. from S. Park View St. to Alvarado St.
• W. 7th St. from Alvarado St. to S. Park View St.

Existing trees will be protected and monitored during the work, according to the Department of Recreation and Parks. Traffic control measures will be in place during work hours, and crews will post temporary “No Parking” signs near active work areas in advance.

Services at the park are expected to remain the same throughout construction. The schedule could change because of weather or other unforeseen circumstances, according to the city.

The city has allocated $2.3 million for the project, but officials have not said whether that will cover the full cost.

After the fence is installed, the city plans a second phase focused on adding decorative elements. Officials have said residents will have an opportunity to provide input on the design.

Residents with questions or concerns about the project can contact Recreation and Parks at RAP.PublicInfo@lacity.org or 213-202-2700.
