"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.”"

1. Smart hives and dancing robot bees could boost sustainable beekeeping

“[Researchers] developed a digital comb—a thin circuit board equipped with various sensors around which bees build their combs. Several of these in each hive can then transmit data to researchers, providing real-time monitoring. [… Digital comb] can [also] be activated to heat up certain parts of a beehive […] to keep the bees warm during the winter[…. N]ot only have [honeybee] colonies reacted positively, but swarm intelligence responds to the temperature changes by reducing the bees' own heat production, helping them save energy.”

2. Babirusa pigs born at London Zoo for first time

“Thanks to their gnarly tusks […] and hairless bodies, the pigs are often called "rat pigs" or "demon pigs” in their native Indonesia[….] “[The piglets] are already looking really strong and have so much energy - scampering around their home and chasing each other - it’s a joy to watch. They’re quite easy to tell apart thanks to their individual hair styles - one has a head of fuzzy red hair, while its sibling has a tuft of dark brown hair.””

3. 6,000 sheep will soon be grazing on 10,000 acres of Texas solar fields

“The animals are more efficient than lawn mowers, since they can get into the nooks and crannies under panel arrays[….] Mowing is also more likely to kick up rocks or other debris, damaging panels that then must be repaired, adding to costs. Agrivoltaics projects involving sheep have been shown to improve the quality of the soil, since their manure is a natural fertilizer. […] Using sheep instead of mowers also cuts down on fossil fuel use, while allowing native plants to mature and bloom.”

4. Florida is building the world's largest environmental restoration project

“Florida is embarking on an ambitious ecological restoration project in the Everglades: building a reservoir large enough to secure the state's water supply. […] As well as protecting the drinking water of South Floridians, the reservoir is also intended to dramatically reduce the algae-causing discharges that have previously shut down beaches and caused mass fish die-offs.”

5. The Right to Repair Movement Continues to Accelerate

“Consumers can now demand that manufacturers repair products [including mobile phones….] The liability period for product defects is extended by 12 months after repair, incentivising repairs over replacements. [… M]anufacturers may need to redesign products for easier disassembly, repair, and durability. This could include adopting modular designs, standardizing parts, and developing diagnostic tools for assessing the health of a particular product. In the long run, this could ultimately bring down both manufacturing and repair costs.”

6. Federal Judge Rules Trans Teen Can Play Soccer Just In Time For Her To Attend First Practice

“Today, standing in front of a courtroom, attorneys for Parker Tirrell and Iris Turmelle, two transgender girls, won an emergency temporary restraining order allowing Tirrell to continue playing soccer with her friends. […] Tirrell joined her soccer team last year and received full support from her teammates, who, according to the filing, are her biggest source of emotional support and acceptance.”

7. Pilot study uses recycled glass to grow plants for salsa ingredients

“"We're trying to reduce landfill waste at the same time as growing edible vegetables," says Andrea Quezada, a chemistry graduate student[….] Early results suggest that the plants grown in recyclable glass have faster growth rates and retain more water compared to those grown in 100% traditional soil. [… T]he pots that included any amount of recyclable glass [also] didn't have any fungal growth.”

8. Feds announce funding push for ropeless fishing gear that spares rare whales

“Federal fishing managers are promoting the use of ropeless gear in the lobster and crab fishing industries because of the plight of North Atlantic right whales. […] Lobster fishing is typically performed with traps on the ocean bottom that are connected to the surface via a vertical line. In ropeless fishing methods, fishermen use systems such an inflatable lift bag that brings the trap to the surface.”

9. Solar farms can benefit nature and boost biodiversity. Here’s how

“[… M]anaging solar farms as wildflower meadows can benefit bumblebee foraging and nesting, while larger solar farms can increase pollinator densities in surrounding landscapes[….] Solar farms have been found to boost the diversity and abundance of certain plants, invertebrates and birds, compared to that on farmland, if solar panels are integrated with vegetation, even in urban areas.”

10. National Wildlife Federation Forms Tribal Advisory Council to Guide Conservation Initiatives, Partnerships

“The council will provide expertise and consultation related to respecting Indigenous Knowledges; wildlife and natural resources; Indian law and policy; Free, Prior and Informed Consent[… as well as] help ensure the Federation’s actions honor and respect the experiences and sovereignty of Indigenous partners.”

Water and electronics don't usually mix, but as it turns out, batteries could benefit from some H2O. By replacing the hazardous chemical electrolytes used in commercial batteries with water, scientists have developed a recyclable 'water battery' – and solved key issues with the emerging technology, which could be a safer and greener alternative.

I really wanna know more about the outsiders world. But mainly the maze. Like yes it's a massive place with an insanely high budget but how realistic is the place that no one noticed something was off for so long.

The sky is fake, the watchers can control the time. But how does rain work? Are there sprinklers on top that no one can see? How advanced is their technology that they can do that?

If cOwen can shoot at the ceiling with no damage how strong is it? You could argue that as he shoots it, it loses power and force but the arrows get stuck in the ceiling. So it definitely lands and hits it with no visible damage.

How does the farming work? Why is it that crops can grow in seconds and do no damage to the land. Is this something they've developed just for the maze? Do they use this outside the maze to solve a world hunger issue? I need answers STARR

I'll take "things that didn't happen but I drew them anyway" for 500, Trebek.

The second picture was supposed to have another panel that consisted of Law just smugly lacing his fingers together and saying, "go on..." but I kinda ran out of steam since it was getting very late.
