Inside Kenya's bold race to solve water scarcity

On an island in Lake Victoria, water surrounds everything. It laps at the shoreline, stretches beyond the horizon, defines the landscape, yet for the families who live there, it is often undrinkable.

"Water is physically abundant, yet functionally inaccessible due to contamination," says Odak Onyango, chief executive of Wable Maji Safi Solutions. "In our context, scarcity is not absence, but contaminated abundance.”

That contradiction—water everywhere, yet not a drop safe to drink—is where this story begins.

But it is not the only form of scarcity in Kenya.

In the country's arid north, the problem is the opposite: water scarcity. And in its cities, a third crisis unfolds more quietly: millions of liters of wastewater are discharged untreated, poisoning the very rivers communities depend on.

Three different crises. Three radically different solutions.

Together, they reveal something larger: a continent no longer waiting for water systems to be fixed, but actively reinventing them.

The end of the long walk

For years, trader Lydia Ngweso's day began before sunrise, at Ogongo, Homa Bay, Kenya.

At 4:00 a.m., she would wake and rush to secure water, joining long queues and competing for a resource that was never guaranteed. The time it took cut into her livelihood as a trader, limiting how much she could earn.

Today, she no longer wakes in the dark. Water is available where she lives, at any hour.

"Water resilience means predictable, reliable, and nearby access," Onyango says. "It directly translates into improved school attendance, economic productivity, and household stability.”

Onyango grew up on an island in Homa Bay County, western Kenya, surrounded by the vast waters of Lake Victoria. Yet over time, the lake became contaminated with pollutants and microplastics. Onyango also witnessed recurring outbreaks of cholera and bilharzia. Contamination, disease, and the high cost to families forced to spend scarce resources on bottled water combined to reveal a deeper systemic failure: proximity to water does not guarantee access to safe water. This confluence of issues led Onyango to create Wable Maji Safi Solutions.

Onyango's model is deceptively simple. The company treats contaminated surface water at the point of need. Solar-powered purification systems sit within communities, embedded with sensors that monitor quality and uptime. Access is managed through mobile payments, turning water into a measurable and traceable service.

"We have effectively productized water," Onyango says, "leveraging Africa's fintech infrastructure to make safe water commercially viable."

The impact is not theoretical. In communities where the systems operate, local clinics have reported declines in waterborne diseases, Onyango says, an early signal of deeper changes.

"We were no longer just supplying water. We were reducing disease burden and easing pressure on fragile rural health systems," he says.

In places like Ogongo, the effects ripple outward. This results in more time for work and school, and more stability in households where water once dictated the rhythm of life.

Across sub-Saharan Africa, Onyango notes, billions of dollars in economic value are lost each year to the simple act of fetching water.

"This is as much a productivity issue as it is a health issue," he says.

Water from Thin Air

Onyango's solution addresses water contamination.

Water scarcity is another story.

For Beth Koigi, CEO and Founder of Majik Water, the realization did not come in childhood, but through contrast.

She grew up in a part of Kenya where water was abundant. It was only later, at university in an arid region, that she encountered a completely different reality.

"Communities were struggling daily to access even the most basic necessity... clean and safe water," she says.

At first, she focused on filtration, helping communities clean what little water they had. But in 2017, one of Kenya’s worst droughts exposed a harsher truth.

"It is one thing to lack clean water; it is far worse to have none at all," Koigi says.

Crops failed, livestock perished, and entire communities were pushed to the brink. It was during this period that a question began to take shape—one that would redefine her approach.

"What if water didn't have to come from the ground at all?" Koigi asked.

Majik Water was Koigi's solution.

"Our solution provides a decentralized, sustainable source of safe drinking water that is solar-powered, does not depend on existing infrastructure, and can operate in off-grid environments. This makes it particularly well suited for remote and water-stressed regions where infrastructure is limited or unreliable," she says.

Solar-powered machines harvest moisture from the air, producing clean drinking water even in regions that appear completely dry. The technology draws no water from rivers or aquifers and does not deplete already strained resources, creating a new supply. In places like Kakuma Refugee Camp in Turkana, northern Kenya, the first encounter with this idea is unforgettable.

"The excitement, relief, and disbelief were powerful," Koigi recalls. "For many, it was the first time they had consistent access to safe drinking water without walking long distances."

At St. Juliet Educational Centre in Kibera, Nairobi County, the transformation has been quieter but just as profound. Kibera is the largest slum in Africa.

Before the installation of an atmospheric water generator, students—especially girls—frequently missed school due to a lack of water for hygiene and sanitation, particularly during menstruation. Afterward, absenteeism dropped.

"With improved hygiene conditions, they are now able to attend school more consistently and with greater dignity and confidence," Koigi says.

Even during school holidays, the system continues to produce water consistently, turning the school into a reliable community source.

"Communities no longer have to rely on water trucking or walk long distances," she adds. "It allows families to plan better, children to stay in school, and small businesses to operate more reliably."

The river that disappeared

For Mshila Sio, founder of Omiflo, the crisis is not just about scarcity. It is about loss.

"When I was a boy, school holidays meant traveling upcountry to Taita," he says. "Their home was across the Voi River, and since there was no road, my father and uncles would wade into the water, carrying us on their shoulders. That rushing river was the lifeblood of the community."

Years later, he returned with his daughter.

"I ended up placing her on a completely dry, sandy riverbed," he says. "She played with the sand, delightfully clueless as to how things had changed."

The realization was immediate and irreversible.

"That was the moment it hit me: we had lost a vast river in a single generation. If we didn't fundamentally change how we manage our water, we were going to lose our future.”

In cities across Africa, the pattern repeats differently but just as destructively. Wastewater, untreated and unmanaged, flows back into ecosystems, degrading them over time.

"Over 90% of the wastewater we produce is discharged entirely untreated," Sio says. "It is destroying our environment and creating public health crises.”

His response is not mechanical, but biological.

Omiflo's Phytofix system uses floating matrices of aquatic plants to treat wastewater naturally. Their roots host bacterial biofilms that break down pollutants, cleaning the water without chemicals or external energy.

"We designed our system to turn hazardous waste into a restorative resource. We don't just treat wastewater—we reclaim it. This ensures it can be safely reused for agriculture, landscaping, or returned to natural water bodies."

The systems are compact, modular, and adaptable, requiring only a fraction of the space of traditional methods, and can be deployed even above ground structures.

But their impact is not only environmental—it is deeply human.

At one school, where pit latrines once produced overwhelming odors, children developed a routine: they would remove their sweaters before entering, to avoid carrying the smell with them all day. Omiflo transformed the pit latrines into low-flush toilets and installed a pan that prevents bad smells from emanating.

After Omiflo's intervention, something small but telling changed.

"We observed that students now walk in with their sweaters," Sio says. "It's a small thing, but very meaningful."

Beyond aid

For decades, water access across much of Africa has depended heavily on aid. These are projects that arrive with urgency but often struggle to sustain themselves. All three founders reject that model.

"Africa does not lack solutions, it lacks aligned systems," Onyango says. "Water systems must transition from charity models to utility-based, revenue-backed models."

Koigi agrees.

"Solutions should generate revenue, even at an affordable level, to sustain operations," she says. "Combining innovation with entrepreneurship, local ownership, and smart financing models can reduce dependence on aid and create systems that are scalable and resilient over time."

Sio is more direct.

"We have to stop treating sanitation as a donor-funded charity and start treating it as a highly profitable, scalable asset class," he says.

The shift they describe is not just financial. It is philosophical. Water, in this framing, is not a temporary intervention. It is infrastructure central to health, education, and economic growth.

"Africa must redefine water as infrastructure, not charity," Onyango says.

The hardest part is not the technology

Despite their breakthroughs, all three founders face a similar obstacle: scale.

"Scaling is not a technology problem, it is a capital and ecosystem problem," Onyango says, pointing to the need for blended finance and policy environments that support innovation.

Koigi echoes the challenge.

"Deploying at scale requires upfront capital investment," she says. "There is also a need to build trust in new technology within communities and institutions."

For Sio, resistance often comes from within systems themselves.

"Trying to convince them to adopt decentralized, nature-based solutions requires shifting deeply entrenched mindsets," he says.

In many cases, regulatory frameworks were designed for centralized utilities, which are large, rigid systems that struggle to accommodate more agile, distributed models. The result is a tension between innovation and the structures meant to govern it.

A different future takes shape

What emerges from these efforts is not a single solution, but a new way of thinking.

In one place, contaminated water is purified at the source. In another, water is created from air. Elsewhere, wastewater is reclaimed and returned to use.

Each approach solves a different piece of the puzzle. Together, they form something larger: a decentralized, climate-resilient water system built from the ground up.

"The future of water in Africa will be driven by technology, renewable energy, and data systems," Onyango says.

Koigi adds a note of urgency:
"The most urgent priority is to invest in solutions that increase water availability without depleting natural resources, while ensuring access for vulnerable communities."

Sio points toward a broader transformation still:
"Success is a circular water economy where no drop of water is wasted, and our cities grow alongside thriving ecosystems, rather than at their expense," he says.

More than water

If these ideas succeed, their impact will extend far beyond access. Health systems will stabilize, time will be returned to households, and economies will grow.

"Success means a future where access to clean, reliable water is no longer a daily struggle. For the continent, it means building resilient, sustainable water systems that support communities, economies, and ecosystems for generations to come," Koigi says.

"For Africa's water future, success looks like a complete paradigm shift. It means reaching a tipping point where dumping waste into the environment is no longer the default because decentralized, affordable treatment is readily available," Sio adds.

"If Africa gets water right, health systems stabilize, economies grow, and governance improves," Onyango says.

It is a simple statement, but one that carries enormous weight.

Across Kenya, in lakeside villages, drought-stricken regions, and crowded cities, the future of water is already being rewritten—not as a story of scarcity alone, but as one of invention.
