After an Orange County resident flushes her toilet, the water flows through the Southern California community’s sewer system, meanders its way to the sanitation plant, has its solids removed, is piped to a wastewater recycling facility next door and undergoes three different purification processes until it is clean enough to drink.

“It tastes like water,” said Mehul Patel, executive director of operations for the Orange County Water District’s project, after taking a gulp from a clear plastic cup at the sampling station, as he stood outside the final purification process facility on a warm afternoon earlier this month.

“It’s just like any other water, but it’s gone through a lot,” he said. “People shouldn’t judge where it came from, but where it is now.”

No large community in the U.S., not even Orange County, is taking water from toilets and transforming it directly into clean drinking water right now. But Patel’s demonstration might offer a glimpse of the future, as states and communities across the country design new plants that will do just that, giving communities more control over their water supply as the climate gets drier.

The idea is still new in many parts of the country. And officials face some pushback from skeptics concerned about the high costs of advanced purification systems and from a public not used to the idea of drinking what was once their own waste.

Every day, Orange County’s Groundwater Replenishment System, known to the locals as GWRS, purifies 130 million gallons of wastewater coming from 2.5 million residents. It’s the world’s largest wastewater recycling plant, and the first in the United States to recycle every ounce of its county’s wastewater. This system of pipes, purifiers and chemical reactions has become a required visit for any water official looking to adopt a similar program in another state.

Patel expects more visitors now that California’s top water officials are slated to greenlight new rules later this month that would allow counties to purify their wastewater and inject it immediately into the drinking water supply. If approved, as expected, regulations would go into effect in July.

Currently, all of Orange County’s recycled wastewater is used to replenish its groundwater aquifer and protect it from seawater intrusion. The water is later pumped out and purified once again to drinking water standards and distributed throughout the county. There are no plans to change this two-part process anytime soon.

Some Golden State communities do the same; others use their recycled wastewater to irrigate fields, water parks or merely dump it into the Pacific Ocean.

But as the state faces a drier future in which the amount of water coming from the Colorado River and the Sierra Nevada Mountains may not be reliable, top water officials say the state needs more sources of drinking water.

“We spend a lot of money and energy moving water from different parts of the state to Southern California, where it’s used once and dumped in the ocean,” said Darrin Polhemus, deputy director of the California State Water Resources Control Board. “That’s maybe not the smartest way to deal with a resiliency question.”

Communities across the country, even beyond the increasingly arid West, have been using recycled wastewater to shore up water supplies drained by larger populations, over-pumped groundwater aquifers, hotter summers and less precipitation.

Facilities are pumping out millions of gallons of recycled wastewater in Arizona, Georgia, Texas and Virginia. Regulators in Colorado, Florida, Iowa and Kansas are considering how to use it. In Arizona, for example, some cities use recycled wastewater to replenish dormant rivers and brew beer; others use it to refill underground aquifers, cool factories or keep parks and golf courses green. But rarely has wastewater gone directly into the drinking water supply.

Daniel McCurry, an assistant professor of civil and environmental engineering at the University of Southern California, expects that in two decades at least half of states will adopt wastewater recycling to meet the hydrological demands of a hotter, drier climate.

“Places you wouldn’t normally think of as dry or water-stressed at all are starting to build these plants,” he said. “And that’s only going to accelerate.

“Anywhere that’s primarily reliant on groundwater is going to have water reuse in their future.”

How it works

The town of Castle Rock, Colorado, lies in a valley east of the Rocky Mountains.

Directly recycling wastewater into drinking water will eventually allow residents to hold onto more of their precious water supply. Rather than continuing to send treated wastewater into East Plum Creek, where volumes can be lost to evaporation, the town will be able to recycle its municipal water over and over at a water treatment plant that was upgraded in 2021.

“We keep more of a closed loop and we bring that water directly back,” said Mark Marlowe, director of Castle Rock Water, of the incoming system.

While the plant already has the capability, it’s not sending treated wastewater directly to customers yet; Marlowe says it will likely take three to five years to meet new regulations on potable reuse announced by the state in January. The rules include a full year of water quality monitoring and a community awareness campaign before implementation.

While Castle Rock will spend more to comply with those regulations, it also expects to save money on energy costs by reducing the distance water must be moved. And the city’s sewage will actually provide more predictable water quality, Marlowe said. The quality of creek water can vary wildly as salt runs off in the winters or as storms increase sediments in the water.

“There is no new water,” Marlowe said. “It’s really just a question of whether the water is being recycled through natural processes or through manmade engineering solutions.”

In Orange County, the science of turning human waste into clean water is on full display.

After showing a Stateline reporter around the 15-acre wastewater recycling plant southeast of Los Angeles, the air around it heavy with the smell of standing water, Patel stopped at three display sinks designed for the tour frequented by local students and water officials from out of town — one filled with amber-tinted water, another yellowish and the third crystal clear, each showing what the wastewater looks like after the three purification steps.

Starting at microfiltration, wastewater is sucked through microscopic holes in hollow plastic fiber. At reverse osmosis, the water is forced through holes 1,000 times smaller in tightly wound membrane sheets, wrapped in fiberglass tubes. And at advanced oxidation, the water is hit with ultraviolet light combined with hydrogen peroxide.

From sewage to drinkable water, the process takes 20 hours.

In the next decade, Southern California cities such as Los Angeles and San Diego plan to recycle wastewater for direct use as drinking water. Both would add more purification steps than what Orange County uses to ensure pathogens are removed before the water reaches consumers.

“As the drought has gotten worse, the interest has increased,” Patel said.

Where it’s going

Even in the typically water-rich Midwest, unpredictable supplies have some communities considering turning wastewater into drinking water.

In southern Iowa, the town of Osceola could become the first in the state to use treated wastewater as part of its drinking supply. Three years of drought have left the town’s West Lake dangerously low, the Des Moines Register reported.

The topic came up time and again at a water conference hosted by the Kansas Water Office last month.

In one presentation, Jason Solomon, a technical assistant at the Kansas Rural Water Association, projected a map of the Neosho River pocked with toilet icons marking the dozens of places communities release treated wastewater into the river. Sometimes, those discharges aren’t far from the intake valve of the next town downstream relying on the water.

His point: The current system is only one step removed from directly recycling wastewater. Rivers and reservoirs are as much a mental barrier as a physical one in terms of water quality, said Solomon, whose group assists small water providers across the state.

He thinks direct wastewater recycling is likely a ways off in Kansas given its stigma and costs. But it’s an idea worth considering with recent droughts threatening drinking water supplies even in the traditionally wettest part of the state.

“Why don’t we just take it directly from the wastewater plant?” he said in an interview. “Why would we put it back in the river? It’s going to get dirtier in the river.”

Public perception is key

Although experts say the science is clear, convincing the public has been a challenge, including in Southern California.

Three decades ago, Los Angeles County sought to bring what the local media dubbed “toilet to tap” to the region, but officials were met with fierce resistance by politicians and residents. It stopped the project.

The “yuck” factor can be challenging, said David Sedlak, director of the Berkeley Water Center at the University of California, Berkeley.

“When you look at some communities where they haven’t done water recycling yet, they have to start building legitimacy from the ground up,” said Sedlak, who recently published a book on water solutions.

“Sometimes that means changing the culture of transparency and openness. And sometimes that means working with the public and bringing them on board to see and understand it.”

Often, people assume the water coming from rivers is cleaner than it really is, Sedlak said; the public may not fully grasp that it can include agricultural runoff or the wastewater from some upstream communities.

A future plant in El Paso, Texas, will include an educational exhibit area so schoolchildren and other visitors can see the science behind the treatment process.

Adjacent to an existing wastewater plant, the $130 million purification facility will send treated wastewater directly back into the drinking water system. Construction is expected to begin next year, but the city has been working to educate and build trust with the public for the past decade, said Christina Montoya-Halter, the communications and marketing director for El Paso Water.

“I don’t want to say it was easy,” she said. “But we are in a different position in El Paso because we’ve been talking about the need to diversify for a long time.”

The city sources water from the Rio Grande and underground aquifers, and runs a desalination plant to treat salty groundwater.

The new treatment plant, which should be running by 2027, is expected to produce up to 10 million gallons per day — or about 6% of the city’s annual needs. But it’s considered a crucial supply since El Paso hasn’t received its full allocation of Rio Grande water in about a decade.

Gilbert Trejo, vice president of engineering, operations and technical services for the utility, said directly treating wastewater will cost roughly double the price of other treatment processes.

Trejo, who serves on the board of a national trade group promoting the use of recycled water, expects directly recycled wastewater will become mainstream as officials increasingly view it as a solution to water shortages.

“It’s not just a solution for arid states and arid regions,” he said. “This also solves a lot of problems in water-rich areas.”

The Clean Water Act, salmonella inspections and equity in the Packers and Stockyards Act are just a few of the regulations that the industry lobbying group the Meat Institute, formerly known as the North American Meat Institute, is calling for the Trump administration to pull back.

On January 27, Meat Institute president Julie Anna Potts penned a letter to the White House providing the new administration with "strategies to reduce burdensome regulations and address meat prices for consumers." In the letter, Potts blames the previous administration for inflation, which she claims was caused by increased regulation in the food industry. Potts also targets increased worker protections against discrimination, which she claims are part of diversity, equity and inclusion practices.

"Based on what they propose, the path to lower food prices is exploiting child labor and engaging in sharecropping production models," Austin Frerick, antitrust expert and author of Barons: Money, Power, and the Corruption of America's Food Industry, tells Sentient. "They're grab-bagging words in the moment to fit their deregulatory race to the bottom."

If Trump takes the advice of this lobbying group - which touts its representation of meat packers and processors that "account for more than 95 percent of U.S. output" of processed meats - experts do not agree that prices will necessarily go down. According to Food & Water Watch staff attorney Emily Miller, the real issue at play is consolidation in the industry.

"We know that the real cost of high food prices in this country is not inflation or the cost of regulatory compliance, as the industry is claiming. It's corporate consolidation and greed," Miller says. "Rolling back regulations that are meant to protect farmers, slaughterhouse workers, frontline communities and consumers from exploitation and pollution will just allow the meat industry to break even more profit."

While food prices have increased at a fast rate - as much as 2.5 times the rate of inflation - corporate profits have sky-rocketed five times faster than inflation. Four companies control around 70 percent of the pork industry and four companies control more than half the chicken processing market.

Even if the industry successfully de-regulates and lowers costs associated with stricter environmental and worker protections, there is no guarantee that would result in lower food prices. Corporations can continue to pocket the difference.

What This Could Mean for Workers

One rule the Meat Institute wants to rescind is the Inclusive Competition and Market Integrity Under the Packers and Stockyards Act. The rule, which went into effect in 2024, "prohibits the adverse treatment of livestock producers and poultry growers based on race, color, religion, national origin, sex (including pregnancy, sexual orientation, and gender identity), disability, marital status, or age."

The Meat Institute claims this rule "attempts to enshrine" diversity, equity and inclusion concepts into the act.

"I think this is definitely a way of baiting Trump to act," Miller says. "What they're really asking, pretty unabashedly, is for the ability to discriminate against other people for personal characteristics that have nothing to do with their business or the economy or anything that would have any sort of justification, which is pretty outrageous."

Another set of protections the Meat Institute targets in its bid to the new administration relates to contract chicken producers - farmers who raise chickens on a contract basis for mega-corporations like Tyson Foods. Passed under the Biden administration, the regulations had been intended in part to help chicken farmers who end up taking on enormous debts as part of their contractual agreements with poultry companies.

What This Could Mean for the Environment

The Clean Water Act is considered one of the cornerstones of environmental protection in the U.S., but when it comes to regulating the discharges from agriculture, it has long fallen short. Clawing back the already weakened regulatory power of the act could further pollute waterways that are already in poor shape, especially in states with increasing density of factory farms. For instance, more than half of rivers and streams are degraded in Iowa - a state where most counties are "severely or highly concentrated with factory farms."

Miller, of Food & Water Watch, notes that the federal government is under a court enforceable settlement that requires them to finalize the rule the Meat Institute wants to disassemble. Any effort to roll that back, she says, would be in direct violation of the settlement.

"The industry would, of course, want the least amount of regulation possible and to maintain the status quo that allows them to really harm the communities that neighbor these operations, which overwhelmingly are low income communities of color," she says.

In states dominated by factory farms, manure discharged into waterways has led to detrimental health outcomes, fish kills and higher drinking water costs.

In addition, much of the meat produced in Iowa factory farms is in turn exported. "We're basically destroying rural communities in the Midwest, notably Iowa, to feed foreign nations," Frerick says. "The environmental destruction these production models do and that says something when it's cheaper to do it here than in China."

Frerick argues that Republican administrations "turbocharge" the race to the bottom with de-regulation, opening the doors for catastrophic changes to not only the food system itself, but consumer trust and confidence that they are getting a safe product.

"You're playing Russian Roulette with people's health and safety. If you have one big scandal, one big outbreak, you could really shift people's consumption and food diets in profound ways that really can wreck an industry," Frerick says.

What This Could Mean for Food Safety

Pulling back proposed salmonella regulation could endanger consumers, Jaydee Hanson, Policy Director of the Center for Food Safety tells Sentient. Meat Institute is calling to replace a proposed rule that would increase monitoring in the poultry slaughter process with "a performance standard with the input of stakeholders."

"I'm concerned that the next thing they'll be pushing for is less aggressive enforcement of rules on E coli," he tells Sentient. "We don't want to go back to poor inspection with state inspectors that are being bribed and say that that's going to give us cheaper meat."

"You want a regulatory system where consumers know they're getting a healthy, safe product that was produced in a way that was ethical," Frerick says. "When you get rid of that, you're incentivizing the worst people."

The Bottom Line

"Any regulatory rollbacks that allow the meat industry to further consolidate its market power will just have the opposite effect on consumers and on food prices generally," Miller says. "Efforts to roll those things back would just continue to inflict harm on the people who are growing and producing our food in this country, and simply give a bigger profit margin to the corporations that are at the top of the food chain."

Though no distinct moves have been made to address the Meat Institute's requests, on January 31, the Trump White House announced a de-regulatory blitz, requiring that "whenever an agency promulgates a new rule, regulation, or guidance, it must identify at least 10 existing rules, regulations, or guidance documents to be repealed."

"Concentrated markets gouge. It's what they do. You see innovation and quality decline," Frerick tells Sentient. "Once you add in the cost, the negative externalities, all the pollution stuff, it's even more expensive. So we're being doubly-screwed, to be blunt."

In Postville, Iowa, a town with a population of 2,503, the slaughterhouse Agri Star Meat and Poultry LLC is the largest employer. Although there is no publicly available data on how many animals are slaughtered at Agri Star every day, in 2010, CEO Hershey Friedman hoped the plant could “process 1,000 head of cattle per day within a couple of years.” In December 2024, three non-profit organizations filed an intent to sue Agri Star for illegally discharging animal waste products into public waterways. The slaughterhouse has until February 21, 2025, to respond and answer how they will comply with the Clean Water Act — or the suit will be filed.

Attorneys working on the current case claim that Agri Star has been violating its National Pollution Discharge Permit — a Clean Water Act rule aimed at limiting excessive pollution from point sources — by illegally discharging large quantities of animal processing waste. Last year, “250,000 gallons of untreated beef processing waste,” flowed into the Postville water supply, the notice states.

Agri Star, formerly known as Agriproccessors, is no stranger to controversy (under different ownership, in 2008 it was the site of one of the largest immigration raids in U.S. history, which also found child labor violations).

“The City of Postville stated that while Agri Star worked to fix the blocked sewer line, Agri Star did not appear to limit or cease production — processing waste continued to flow to the City’s treatment system at a rate of 148 to 164 gallons per minute,” the attorneys wrote. This resulted in “an interference with the City of Postville’s normal wastewater treatment process,” which is a violation of their permit. As a result, the Postville water treatment facility was shuttered for two days.

The intent to sue notice was co-authored by Driftless Water Defenders, a non-profit Iowa-based group working to protect Iowa waterways from agricultural polluters, as well as Public Justice and FarmSTAND, both non-profit legal advocacy groups.

“We’ve got a very powerful structure of industrial agriculture that has found a way to feel immune to the pressures of individual citizens to rebuff them, particularly on political fronts,” counsel for the Driftless Water Defenders board of directors James Larew tells Sentient. “They’re so strong and that litigation is a critical ingredient that we need, because the laws like this one are on the books. They need to be enforced. And so we state that we’re there to litigate.”

A State Built on Animal Agriculture

Iowa is at the forefront of what some experts are calling a water quality crisis. As the state with the most animals being raised in confinement, animal waste, which is often illegally discharged, has become a central component of Iowa life.

Chris Jones, a water quality expert and president of Driftless Water Defenders, explains that prior to the passage of the Clean Water Act, Iowa’s waterways were completely “dead” due to slaughterhouse discharges. The Clean Water Act changed things — but without enforcement, the law obviously becomes less efficacious.

“Our [Department of Natural Resources] is not exactly zealous about enforcing rules and doing things that are going to improve the quality of our water,” Jones tells Sentient. “Anybody with eyes and ears in their head can see and hear that. I think they’re reluctant to do things that might appear to be unfriendly to industry or to agriculture, and as such, they sort of abdicated their role as a deterrent for these sorts of things.”

The overwhelming majority — 99 percent — of farmed animals in the U.S. are raised in factory farms. In Iowa, there are over almost 124 million farmed animals; around 55 million chickens, 53.4 million hogs, 11.5 million turkeys, and 3.7 million cattle and cows. With a new federal administration, Jones predicts that the livestock industry has the potential to expand even further, and regulations could diminish.

To demonstrate the extent of this issue, Jones poses a hypothetical scenario: What if the Des Moines wastewater treatment plant did not follow their pollution discharge permit requirements and decided to dump unlimited quantities of human waste into the Des Moines river, poisoning the water supply of a community 75 miles downstream?

“That’s essentially what [the Department of Natural Resources] is doing,” he says. “They’re just saying, okay, Agri Star, go ahead, dump whatever you want into the stream.”

The Iowa Department of Natural Resources and the Environmental Protection Agency have recently come under scrutiny for not enforcing these discharge permits strongly enough. Several groups sued the EPA for their lack of enforcement under the Clean Water Act, and in October 2024 the court struck them down.

Holding polluters accountable through targeted lawsuits, Larew tells Sentient, is one potential path forward.

The Iowa Department of Natural Resources declined to comment due to pending litigation.

Private Attorneys General

In lieu of strong federal or statewide enforcement, these legal groups see themselves as “private attorneys general,” Public Justice attorney Daniel C. Snyder says. To remedy the harm caused by these discharges, the groups are calling for civil penalties against Agri Star.

“Those civil penalties are meant to deter these exact types of violations. You have a penalty that is high enough so that everyone goes, ‘Wow. We should take notice of that. We should make sure we’re complying with our permits so that Driftless Water Defenders or other groups don’t come around and say, hey you you are also in violation of the act,’” Snyder tells Sentient.

For these advocacy groups, the goal is not to put these operations out of business. Larew emphasizes that they are simply using public information and public laws to hold polluters accountable.

“I think there’s a public realization these last couple years in particular, that something’s really out of whack, that we feel threatened with the quality of our water,” Larew says. “[We have an] imbalance right now with the new industrial agricultural model, the concentration of livestock into particular areas, with waste so concentrated that it can’t be adequately used and it ends up being in our water.”

Agri Star did not respond to multiple requests for comment.

Watchdog groups said the West Virginia Department of Environmental Protection seems poised to allow coal company Keystone West Virginia to walk away from its obligation to treat acid mine drainage at a 160-acre surface mine near Marmet, in Kanawha County.

When a company is done mining and is done doing required reclamation work, it will ask the state to return the bond money given when it received its permit to mine. But in this case, the company has not done the cleanup.

Chad Cordell, coordinator for the Kanawha Forest Coalition, said the company has been involved in numerous complaints related to water pollution in Lens Creek.

"This is really a push where we're telling the DEP, not only do you need to not grant this bond release, but you really need to start enforcing the water quality laws and get this company to deal with this water pollution," Cordell outlined.

Keystone West Virginia has been plagued with regulatory problems and lawsuits. The mine the company is seeking for bond release has received 36 notices of violations and 12 cessation orders since it was first permitted, according to the coalition.

Cordell added decades of research and lived experience from residents show the high levels of heavy metals from acid mine drainage, which color the water a coppery brown, can cause permanent damage to drinking water quality, local infrastructure including bridges, public water and power plant supplies, and public health.

"There's really no debate about that at this point," Cordell contended. "We know that there are all sorts of health impacts from these mines. A lot of that is connected to the water impacts of these mines."

There are roughly 400 miles of freshwater trout streams in West Virginia that are impaired because of increased acidity levels from acid mine drainage, according to the West Virginia Water Research Institute.
