Containerized solar water farms provide clean water, jobs for locals

More than 2 billion people globally lack access to clean drinking water, according to the Centers for Disease Control and Prevention. Nonprofit organization GivePower is aiming to reduce that number by using the sun’s energy, shipping containers, desalination technology and local supply chains.

GivePower builds and delivers containerized solar-powered water farms that desalinate salty water. The organization focuses on areas where “there’s an immediate and growing need for better access to safe water,” Kyle Stephan, vice president of operations at GivePower, told FreightWaves.

Austin, Texas-based GivePower started by installing solar panels for schools, community centers or other projects in communities in need. But GivePower founder Hayes Bernard realized that people, especially women and girls, would not attend school if they had to walk 8 miles to get water every day. That’s when the idea to include water pumps and desalination came to mind. 

While some people have no reliable water sources near them, others rely on contaminated or brackish water to drink, clean and cook with. Brackish water is saltier than fresh water but not quite as salty as seawater. 

The CDC estimates that drinking contaminated or brackish water causes:

  • 446,000 deaths among children younger than 5 years old annually.
  • 3 million cases of cholera and 95,000 cholera deaths each year.
  • 11 million cases of typhoid fever and 129,000 typhoid fever deaths annually.

GivePower has seven operational desalination sites in countries like Haiti, Kenya and Colombia. Four additional solar water farms are expected to become operational by the end of this year.

“I think there’s a lot of really exciting things we can do in all of those places to help move the needle around access to clean drinking water,” Stephan said.

Containerized solar water farms

GivePower has different sized desalination sites and setups. The largest one, the Solar Water Farm Max, produces up to 18,500 gallons of water daily — enough to support 35,000 people. It has a solar structure that acts like a roof over the water tanks and the twenty-foot equivalent unit shipping containers that house the desalination technology.

The organization has solar water farms that can produce 4,000 gallons of water or 1,600 gallons of water each day, depending on the needs of the area. Some of these models have solar panels that fan out on top of the shipping container.

GivePower had to choose a structure that would withstand harsh conditions such as hurricanes and earthquakes that these areas commonly experience. Shipping containers are “really well suited to that,” Stephan said.

GivePower typically buys shipping containers that have been used once to transport imported goods from China. The water filtration system is then installed and tested in an off-grid setting in Texas before they are shipped out to their destinations.

“They were ecologically friendly in that they had already been produced. This was an existing thing that we didn’t have to build from scratch,” Stephan said.

Local economy impacts

Because these systems are complicated, they require regular maintenance and care to remain operational. GivePower employs locals in roles for management and site-level staff to do all of the maintenance, operations, water sales, distribution, human resources and accounting. In Kenya, GivePower has more than 40 employees, including four technicians.

“What really makes this unique is we took a longer-term view of these projects and said it’s not good enough that we just provide this equipment into these communities and then kind of cut the ribbon,” Stephan said.

GivePower sells its water at or below the cost of untreated water in the area. That revenue stream is used to pay employees onsite.

In addition to supporting local workers through employment, GivePower’s desalination plants have beneficial impacts on the economics, health and education of surrounding communities.

“They have a really dramatic effect on the communities that we operate in,” Stephan said. Communities have seen marked declines in waterborne diseases such as typhoid and cholera.

It’s hard to quantify all of the impacts that having reliable access to affordable, clean water can have on communities. People are more likely to go to school and pursue other occupations when they don’t have to spend hours a day fetching water that may not be safe to drink.

“That last-mile distribution in some of these remote communities is actually really challenging. It’s the hardest part to solve,” Stephan said.

Water pipe networks are rare in many remote parts of the world. GivePower sometimes hires security and delivery truck drivers to distribute water to the community.

“We also see a lot of third-party distribution,” Stephan said. Many of the locals who sell or distribute water already had a transportation business with tuk-tuks, motorcycles or trucks. They buy water directly from GivePower and then sell it to people in the area.

A water kiosk owner in Likoni, Kenya — one of GivePower’s locations — said, “Life is different now, and we have our own money.”

Choosing optimal locations

Several of the locations GivePower chooses are in coastal areas where there is plenty of water, but it’s not safe for drinking. In islands or coastal communities, GivePower draws in and purifies water directly from the ocean.

There are some places where drilling a well and using chlorine or filtration will provide a clean water source. GivePower is focused on “those more challenging water sources [such as] seawater, brackish water, what’s called nontraditional water sources,” Stephan said.

Getting solar panels and the desalination systems delivered and installed in these sometimes very remote areas can range from simple and boring to quite challenging, Stephan said. In Kenya, GivePower uses flatbed trucks and cranes to move the containers and place them on concrete pads.

“We’ve had some interesting applications where the communities are far too remote and cranes aren’t available. I’ve seen some really impressive videos of people getting these things up onto logs and sort of rolling them across these logs using just manpower — just a bunch of people pushing them into place. It’s pretty impressive the ingenuity that some of the local communities, especially in the remote areas, will come up with to get them in the right place,” Stephan said.

The smaller systems have an integrated solar panel rack that mounts on top of the container that takes less than two hours to set up. The larger systems use a crane to set up columns and the main structure before teams use scaffolding to hang the solar panels that shade the container system and water tanks below.

Likoni location

Likoni is a low-income community of about 200,000 people on the southeast coast of Kenya, bordering the Indian Ocean. On the outskirts of Mombasa, Likoni experiences extreme water scarcity and relies on imported water.

“When we think about water, we just think it’s a basic need, it’s normal. But for the people of Likoni, water is like the gold you have to really dig to get,” Ruth Ndung’u, site manager at GivePower Kenya, said in a video.

People in Likonia may pay twice the amount they pay for rent to get enough water for the month.

“Having clean water has made such a big impact [on] this community. Think about the father who now does not have to continuously take his children to the hospital because of typhoid or cholera or the mom who has a small eatery and now knows that her food will be delicious,” Ndung’u said.

Dealing with global supply chain issues

The shortage and steady rise in cost for shipping containers have impacted GivePower, especially since it relies on donations to deploy new solar water farms. 

“The global supply chain right now is proving to be rather challenging,” Stephan said. Tariffs, local regulations and taxes can impact the cost and timeline for desalination projects. There are also certain parts that are hard to get right now, such as pumps and chips. Items that used to take three months to get are now taking six months or longer. 

Luckily, solar panels haven’t been as difficult to obtain since GivePower typically sources them from local suppliers in the country where it sets up desalination plants.

Haitians helping Haitians

A 7.2 magnitude earthquake that hit Haiti in August 2021 caused a lot of infrastructure damage. GivePower’s desalination plant on a little island off the coast of Haiti called La Gonâve “became one of the largest water utilities that was still operating after the earthquake,” Stephan said.

The organization rallied with partners to launch a large-scale relief effort, delivering tens of thousands of gallons of water a day from the island to the mainland to affected communities.

Haiti heavily relies on foreign aid, so it was unique to see Haitians working for GivePower help other Haitians in this crisis, Stephan said.

    Great Story and review.
    One comment stood out to me ” Now we have are own Money” meaning they we no longer waiting on the government to support them.
    Africa biggest hurdle, get out from depending on the government to support you life style.

    Again, thank for sharing this, we have been working in West Africa, Liberia since 2003, and know all to well the challenges.
