We help families sanitize their own water with sunlight.
Sulis: Redefining Liquid Sunshine!
First, families fill up Sulis with dirty water before heading off to work and school.
Over the course of the day, our proprietary metal catalyst harnesses sunlight to clean the water.
By the time the family returns home, they have clean water to be used both for that evening and stored for the next day.
A summary of our pilot program in India.

Date You Started Your Project Started
Project Stage: Select the description below that best applies to your approach.
Start-Up (first few activities have happened)
1. The Problem: What problem are you helping to solve?
Two billion people worldwide currently rely on water sources contaminated by chemicals and pathogens for their everyday needs, making access to clean water is a luxury that cannot be taken for granted. Despite vast improvement in water technology in recent decades, there are still more people dying every year from lack of access to safe water than from all forms of violence combined, including war.
2. Your Solution: How are you planning to solve this problem? Share your specific approach.
Our device is a solar-activated water sanitization device that decomposes organic contaminants and neutralizes pathogenic species in a container of water. Specifically, the sunlight activates our photocatalyst which generates radical oxidative species to degrade organic chemicals and bacterial or viral species present in the water.
3. Personal Journey: What’s the story behind why you decided to start this project?
The concept for the social innovation project and the device was inspired by my sojourns to India to visit family and friends. I often noticed how people living in rural communities relied on groundwater, pond water, and other water sources that were often contaminated or generally unsafe for drinking. When I entered university, I took a course in which I had an opportunity to research this issue more deeply and discovered the global scale of clean water scarcity. After the completion of the course, I decided to translate my academic project into a real social innovation venture, leading to the creation of Sulis.
4. Selfie Elevator Pitch: Include 1-minute video that answers the following “I am stepping up to make change because...”
I am stepping up to make change because I wish to have a positive impact on a global scale by helping to uplift my own community in India and others like it across the world.
(Note: We tried uploading the video several times, but we kept getting an error message. We can send it via email if possible. Please let us know.)
5. Example: Please walk us through a specific example of what happens when a person or group gets involved with your project.
Last summer, we partnered with two universities in India to conduct pilot programs in India and test our technology on-site and within our target communities. In Mumbai, we worked with the Indian School of Management and Entrepreneurship to understand the specific needs of urban slum residents, the current sources of water that they use, and the types of improvements that they would like to see. Similarly, in rural Gujarat, we worked with Ganpat University to conduct field tests of our device and interacted with rural villagers to understand their specific context and needs. We used the information gathered to improve our technology and launched pilot sales programs. We were able to generate approximately 25 door-to-door sales in Mumbai and we received three purchase orders from NGOs in Gujarat.
6. The X Factor: What is different about your project compared to other programs or solutions already out there?
The Sulis technology improves upon existing technologies and methodologies by reducing cost and increasing sustainability. We recognize that clean water has multiple uses, not just for drinking. It is for this reason that we have designed our device to decrease sensitivity to turbidity and to retain functionality during extended periods of cloudy or stormy weather, such as during the monsoon season in South Asia. Unlike other water sanitation technologies, Sulis does not depend on replaceable parts and does not require any regular maintenance for over five years.
7. Impact: How has your project made a difference so far?
We pioneered cross-border collaborations with universities in India, crowdfunded $40,000 to support our venture, developed an affordable water sanitization device for low-income families in India, and generated three ₹100,000 purchase orders from NGOs along with preliminary door-to-door sales in the slums of Mumbai. In addition, we spoke with over 50 families as part of our market validation phase and built strategic partnerships with several NGOs and CSR divisions of major corporations.
8. What’s Next: What are your ideas for taking your project to the next level?
This past summer, we filed a patent for our technology and are working with our strategic partners in India towards large-scale commercialization to deliver our technology to communities in need.
