🚀 A Teenager with a Mission
At just 14, Athalya Soto (pseudonym) from Colombia set out to solve one of the world’s biggest problems: access to safe drinking water. As she told Fast Company, she wasn’t planning to become a famous inventor—she just wanted a simple way to purify water using local materials.
🧪 How It All Started
Athalya’s journey began in her own home laboratory. Inspired by her science teacher and supported by her family, she experimented with designs made from clay, sand, charcoal, and fabric filters. She worked relentlessly, late into the evenings, determined to build something that would actually help people in remote, rural areas.
“If I can build something here, I believe others can too,” she explained in the interview.
🌟 The Purification Breakthrough
After months of prototyping and testing, Athalya arrived at a stacked filter system:
- Clay pot as the outer container
- Charcoal layer for removing chemicals and odor
- Sand and gravel to trap particles
- Fabric layer to polish clarity
This filter removes 99% of bacteria and parasites—not enough to drink from the tap, but drastically safer and far cheaper than most commercial filters.
💸 Affordability by Design
One of Athalya’s main goals was low cost. Her purifier costs only about $10 in materials, compared to hundreds for other devices. Plus, everything is sourced locally, making it easy for rural families to build and maintain themselves.
There are no complex electronics — just earth, wood, cloth, and ingenuity — which makes it ideal for off-grid communities.
🏆 Recognition & Results
Once her prototype worked in the lab, Athalya entered a local science fair—and won first place. Fast Company published her story, spotlighting her design as an example of resourceful innovation.
Local NGOs have also expressed interest. They see Athalya’s setup as a potential game-changer to reduce waterborne illnesses in remote regions without relying on expensive infrastructure.
🌍 Why This Matters
- Global Water Crisis: Over 2 billion people lack safe drinking water. Simple solutions like Athalya’s can make a real difference.
- Empowerment & Education: Seeing a young girl succeed empowers other kids—especially girls—to take on STEM challenges.
- Sustainable Impact: Her design is durable, repairable, and doesn’t create electronic waste.
📚 STEM + Social Good
Athalya’s story reminds us that science isn’t just for labs or corporations. It’s a tool for communities. She shows young inventors that tinkering in your backyard can lead to global impact.
Regular updates from her workshop show her already improving the design—working on faster flow rates and better durability.
🤝 What You Can Do
- Share her story on social media 🎉
- Donate to NGO efforts that help scale her idea
- Encourage young learners in your life to pursue hands-on STEM projects
🎯 Final Takeaway
A 14‑year‑old girl’s passion turned into a practical water purification solution—one that costs next to nothing, uses local materials, and delivers real results. Athalya’s invention reminds us that big change often begins with small, smart ideas.
