Water Treatment Plant in Hyderabad

"Namibia is the driest country in Sub-Saharan Africa, and home to two of the world’s most ancient deserts, the Kalahari and the Namib. The capital, Windhoek, is sandwiched between them, 400 miles away from the nearest perennial river and more than 300 miles away from the coast. Water is in short supply.

It’s hard to imagine life thriving in Windhoek, yet 477,000 people call it home, and 99 per cent of them have access to drinking water thanks to technology pioneered 55 years ago on the outskirts of the city. Now, some of the world’s biggest cities are embracing this technology as they adapt to the harshest impacts of climate change. But Namibia leads the way.

How did this come about? In the 1950s, Windhoek’s natural resources struggled to cope with a rapidly growing population, and severe water shortages gripped the city. But disaster forced innovation, and in 1968 the Goreangab Water Reclamation Plant in Windhoek became the first place in the world to produce drinking water directly from sewage, a process known as direct potable reuse (DPR). 

That may sound revolting, but it’s completely safe. Dr Lucas van Vuuren, who was among those who pioneered Windhoek’s reclamation system, once said that “water should not be judged by its history, but by its quality”. And DPR ensures quality. 

This is done using a continuous multi-barrier treatment devised in Windhoek during eight years of pilot studies in the 1960s. This process – which has been upgraded four times since 1968 – eliminates pollutants and safeguards against pathogens by harnessing bacteria to digest the human waste and remove it from the water. This partly mimics what happens when water is recycled in nature, but Windhoek does it all in under 24 hours...

“We know that we have antibiotics in the water, preservatives from cosmetics, anti-corrosion prevention chemicals from the dishwasher,” Honer explains. “We find them and we remove them.”

Honer adds that online instruments monitor the water continuously, and staff ensure that only drinking water that meets World Health Organisation (WHO) guidelines is sent to homes. If any inconsistencies are detected, the plant goes into recycle mode and distribution is halted until correct values are restored. 

“The most important rule is, and was, and always will be ‘safety first’,” says Honer.  The facility has never been linked to an outbreak of waterborne disease, and now produces up to 5.5m gallons of drinking water every day – up to 35 per cent of the city’s consumption.

Namibians couldn’t survive without it, and as water shortages grip the planet, Windhoek’s insights and experience are more important than ever.

Interest from superpowers across the globe

In recent years, delegations from the US, France, Germany, India, Australia, Singapore, and the United Arab Emirates have visited Windhoek seeking solutions to water shortages in their own countries. 

Megadrought conditions have gripped the US since 2001, and the Colorado River – which provides 40 million people with drinking water – has been running at just 50 per cent of its traditional flow. As a result, several states including Texas, California, Arizona and Colorado are beginning to embrace DPR.

Troy Walker is a water reuse practice leader at Hazen and Sawyer, an environmental engineering firm helping Arizona to develop its DPR regulations. He visited Windhoek last year. “It was about being able to see the success of their system, and then looking at some of the technical details and how that might look in a US facility or an Australian facility,” he said. “[Windhoek] has helped drive a lot of discussion in industry. [Innovation] doesn’t all have to come out of California or Texas.”

Namibia has also helped overcome the biggest obstacle to DPR – public acceptance. Disgust is a powerful emotion, and sensationalist ‘toilet to tap’ headlines have dismantled support for water reuse projects in the past. Unfortunately, DPR’s biggest strength is also its biggest weakness, as the speed at which water can re-enter the system makes it especially vulnerable to prejudice, causing regulators to hesitate. “Technology has never been the reason why these projects don’t get built – it’s always public or political opposition,” says Patsy Tennyson, vice president of Katz and Associates, an American firm that specialises in public outreach and communications.

That’s why just a handful of facilities worldwide are currently doing DPR, with Windhoek standing alongside smaller schemes in the Philippines, South Africa and a hybrid facility in Big Spring, Texas. But that’s all changing. Drought and increased water scarcity worldwide are forcing us to change the way we think about water. 

Now, the US is ready to take the plunge, and in 2025, El Paso Water will begin operating the first ‘direct to distribution’ DPR facility in North America, turning up to 10m gallons of wasterwater per day into purified drinking water – twice as much as Windhoek. San Diego, Los Angeles, California, as well as Phoenix, Arizona are also exploring the technology."

Of course, DPR is not a silver bullet in the fight against climate change. It cannot create water out of thin air, and it will not facilitate endless growth. But it does help cities become more climate resilient by reducing their reliance on natural sources, such as the Colorado River. 

As other nations follow in Namibia’s footsteps, Windhoek may no longer take the lead after almost six decades in front.

“But Windhoek was the first,” Honer reminds me. “No one can take that away.”"

Started the day by reading this article from the NY times, and I'm frankly, disturbed.

Some highlights:

"For decades, farmers across America have been encouraged by the federal government to spread municipal sewage on millions of acres of farmland as fertilizer. It was rich in nutrients, and it helped keep the sludge out of landfills."

Which I knew, and I knew that there were concerns about contaminants from like, the medications people were on. But human waste is part of the nutrient cycle, and it always made sense to me that it should be throughly composted and returned to agricultural lands, and I assumed that people in general were taking the steps necessary to make it safe.

But here's what I didn't know:

"The 1972 Clean Water Act had required industrial plants to start sending their wastewater to treatment plants instead of releasing it into rivers and streams, which was a win for the environment but also produced vast new quantities of sludge that had to go somewhere."

Which, yay, no longer polluting bodies of water, but now that means we're applying industrial waste water to agricultural lands. And have been since 1972. Which leads to this situation, among many others, I'm sure:

"The sludge that allegedly contaminated the Colemans’ farm came from the City of Fort Worth water district, which treats sewage from more than 1.2 million people, city records show. Its facility also accepts effluent from industries including aerospace, defense, oil and gas, and auto manufacturing. Synagro takes the sludge and treats it (though not for PFAS, as it’s not required by law) then distributes it as fertilizer."

So here's what some states are doing:

"In Michigan, among the first states to investigate the chemicals in sludge fertilizer, officials shut down one farm where tests found particularly high concentrations in the soil and in cattle that grazed on the land. This year, the state prohibited the property from ever again being used for agriculture. Michigan hasn’t conducted widespread testing at other farms, partly out of concern for the economic effects on its agriculture industry.

In 2022, Maine banned the use of sewage sludge on agricultural fields. It was the first state to do so and is the only state to systematically test farms for the chemicals. Investigators have found contamination on at least 68 of the more than 100 farms checked so far, with some 1,000 sites still to be tested.

“Investigating PFAS is like opening Pandora’s box,” said Nancy McBrady, deputy commissioner of Maine’s Department of Agriculture."

This is fun:

"The E.P.A. is currently studying the risks posed by PFAS in sludge fertilizer (which the industry calls biosolids) to determine if new rules are necessary.

The agency continues to promote its use on cropland, though elsewhere it has started to take action. In April, it ordered utilities to slash PFAS levels in drinking water to near zero and designated two types of the chemical as hazardous substances that must be cleaned up by polluters. The agency now says there is no safe level of PFAS for humans...

It’s difficult to know how much fertilizer sludge is used nationwide, and E.P.A. data is incomplete. The fertilizer industry says more than 2 million dry tons were used on 4.6 million acres of farmland in 2018. And it estimates that farmers have obtained permits to use sewage sludge on nearly 70 million acres, or about a fifth of all U.S. agricultural land."

There's more, but I wanted to condense it at least a little bit. I am glad we're raising awareness, and I'm glad we're starting to regular the amount in our drinking water, and I hope that we'll find a way to actually deal with PFAS. I am so frustrated that people are exposed in the first place, and in nigh inescapable ways.

Also, to all those people who were like, oh, organic isn't at all healthier for consumers? Guess what the organic standards don't allow to be applied?

Indian IT Worker Designs New Eco-Friendly Sewage Treatment Method with the Sacred Cow as His Inspiration https://www.goodnewsnetwork.org/indian-it-worker-designs-new-eco-friendly-sewage-treatment-method-with-the-sacred-cow-as-his-inspiration/

Tharun Kumar began to imagine ways to build a better sewage treatment method that could produce good quality water without chemicals.

In 2017, Kumar started ECOSTP with the chambered stomach of the cow as his “bovine inspiration.”

Typical wastewater plants use aerobic bacteria, or metabolism with oxygen, to break down sewage, but this requires the ventilation system that continually runs on energy. Regular sewage treatment also tends to use chemicals, and has the presence of a full-time employee. Kumar has eliminated almost all of these drawbacks.

At the base of the ECOSTP septic tank is a layer of cow dung that provides the bacterial workers. With the water moving via gravity, it enters the second bacterial chamber before passing into the third space which is a filter of sand and gravel. The fourth chamber lies under a garden of select vascular plants which removes suspended solids, pathogens, nitrogen, and phosphorus, the latter two going to feed the plants.

The resulting water is graded by health inspectors as good quality for toilet water and gardening applications. With the aid of a grant from the US-based Biomimicry Solutions, ECOSTP now has 325 clients across 22 states in India, and their septic tanks are unmanned and unpowered, saving thousands in running costs.

“We are proud to have reclaimed 2 billion liters of sewage so far without power or chemicals.”

ECOSTP is now seeing if it’s possible to identify anaerobic bacteria that can remove the harmful compounds of industrial effluent.

Excerpt from this Truthout story:

Local officials, academic researchers, and volunteer responders have raised concerns about chemical and biological contamination brought by the floodwaters of Hurricane Helene in the southeastern U.S. last week, which potentially threaten the safety not only of drinking water but also the quality of soil — leading experts to call for tighter regulations on stored pollutants.

The biological and chemical threats posed by floodwaters are typically manifold, often containing, for example, e. coli from overflowing sewage systems.

While it’s not yet clear what bacteria or chemicals Helene’s floodwaters may have contained, the storm passed through hundreds of industrial sites with toxic pollutants, including paper mills, fertilizer factories, oil and gas storage facilities, and even a retired nuclear plant, according to three researchers at Rice University, writing in The Conversation this week.

The researchers called for tighter regulations on the storage and release of chemical pollutants.

“Hazardous releases remain largely invisible due to limited disclosure requirements and scant public information,” they wrote. “Even emergency responders often don’t know exactly which hazardous chemicals they are facing in emergency situations.”

“We believe this limited public information on rising chemical threats from our changing climate should be front-page news every hurricane season,” they added. “Communities should be aware of the risks of hosting vulnerable industrial infrastructure, particularly as rising global temperatures increase the risk of extreme downpours and powerful hurricanes.”

The devastation of infrastructure and the lack of drinking water in cities such as Asheville, North Carolina, has rightly received national media attention following the storm. In North Carolina alone, more than 700,000 households lost power, and 170,000 still didn’t have it as of Thursday.

Yet the National Weather Service warns that while floodwaters can create clear-cut devastation, “what you can’t see can be just as dangerous.” Helene also brought with it public health concerns that are less obvious, including to other, non-public sources of drinking water.

Helene’s floodwaters overran many wells, rendering them unsafe to drink, at least until treatment and testing can be done. North Carolina’s Department of Health and Human Services advised residents not to use contaminated well water earlier this week.

One problem following Helene is that most studies of flooding’s impact on drinking water have been done in coastal areas, and it’s not clear how they apply to the mountainous areas of North Carolina that took the worst hit from the storm.
