Turning seawater into drinking water: A startup aims to transform life on a Colombian island
According to the United Nations (UN), the world is in an era of “global water bankruptcy.” In Latin America alone, the OECD finds that 17 million people still lack access to safe drinking water. Among those affected are the residents of Tierra Bomba, a small Caribbean island located off the coast of Colombia which faces persistent challenges in obtaining drinking water.
The island, home to an estimated 9,000 people, lacks access to clean water, with residents relying almost entirely on supplies brought in by boat from the mainland.
However, water filtration startup Vital Lyfe and Amigos Del Mar, a local NGO, recently made a breakthrough for the island’s water supply; in November last year, they successfully tested a decentralized water system, which can turn seawater into treated filtered water. So far, 40 families in the area have been helped by the project, benefitting from stable water production with minimal maintenance.
“Everyone knows that water is extremely expensive here,” Marta Maldonado, a Tierra Bomba local, told The Bogotá Post. “One gallon costs three thousand pesos. As a family, we have to buy four gallons of water every single day just to start the day. Many times, the water arrives with a little bit of salt in it, and that has even made us sick.”
For Maldonado, Vital Lyfe and Amigos Del Mar’s work has made drinking water more accessible. “Drinking the water filtered by Tierra Bomba’s technology is something special. It makes me realize that good water has finally arrived here. We have the sea right in front of us, and now, with these machines, clean water becomes possible. For us, it is something essential,” Maldonado said.
Making seawater drinkable
As an island, Tierra Bomba faces significant challenges. For instance, there is a lack of running water and sewage systems, issues with gas access, and inefficient trash collection that can make life difficult for residents.
“One of the biggest problems that we see in Tierra Bomba is clean water access. The water comes by boat, and it can be expensive, inconsistent, and sometimes of questionable quality. The water gets to the island, and people have to go and buy it in one place, making it really hard for some people to carry water to their homes,” Pedro Salazar, president and founder of Amigos Del Mar, told The Bogotá Post.
Amigos del Mar, established in 2015, decided to collaborate with Vital Lyfe to see if there was a way to create more reliable water access for the island. “Water is life. It brings health when a lot of the unsanitary water in the area carries diseases that people have been consuming. The quality of life for the people of Tierra Bomba can become much better, as we have already seen with this pilot, when they have access to good quality water for everything in their lives, from drinking to cleaning to cooking,” Salazar said.
Under the hood
The project uses a portable filtration system built by Vital Lyfe, which offers a high-efficiency purification engine that combines mechanical innovations such as low-cost reverse osmosis membranes, and smart power management to deliver clean water without the industrial footprint normally associated with purification. The device can adapt to the water that is available, using the lowest energy, and implementing the most efficient treatment pathway for that specific source.
This approach enables the system to process naturally occurring water sources, including brackish water, seawater, and freshwater, to eliminate salts and biological contaminants so the water can be made into drinkable, filtered water.
“The project was a great success, with the technology working immediately, providing filtered water for around 40 families in the area. Many more became aware of the system and expressed interest as well, providing a need for more of this kind of tech. The mission achieved field validation for us as well, proving that the technology could work in remote environments with little knowledge or maintenance needed from the local community,” Jon Criss, CEO and co-founder of Vital Lyfe told The Bogotá Post.
Criss notes that the local community assisted with the rollout, unloading and positioning equipment before installation began. The project means that rather than having to rely on a fragile supply chain which is vulnerable to changing weather conditions, community members can enjoy sustainable access to clean water that’s local and scalable.
“For us, this wasn’t just a one-off deployment. It was proof that communities like Tierra Bomba don’t have to stay dependent. There’s real potential here to expand the impact and build something long-term that strengthens resilience and lowers cost at the same time,” Criss said.
While the pilot looks promising, it also remains to be seen if the equipment can sustain prolonged use. In addition, there is more research to be done, to demonstrate that such a filtration solution could provide filtered drinking water to more populated areas.
