What specific problem are you solving?
Rural Sri Lankan communities face severe water insecurity due to erratic rainfall, prolonged droughts, and poor water infrastructure — all exacerbated by climate change. Over 35% of rural schools lack reliable access to clean water, affecting health, hygiene, and education. At the same time, wastewater from limited sources is often wasted or causes contamination, worsening local water cycles.
This problem affects millions globally — over 2 billion people live in water-stressed regions, and climate change is projected to displace 700 million due to water scarcity by 2030. In Sri Lanka, seasonal droughts and increasing salinity threaten the most underserved: rural school children, farmers, and marginalized communities.
Existing technologies exist but are often expensive, centralized, or not designed for off-grid, low-income rural areas. Our solution directly addresses this infrastructure and climate gap by combining renewable energy, clean water access, and water reuse into one affordable, scalable, and community-led system.
What is your solution?
SunSpring Hubs are decentralized, solar-powered water and sanitation systems designed for rural schools and communities. They provide:
Solar pumping of water from natural wells to schools or village centers.
An in-house developed greywater recycling unit that purifies used water from sinks and handwashing stations for reuse in toilets or agriculture.
IoT-based sensors that monitor water flow, quality, and solar performance, with mobile-accessible dashboards.
Offline-first educational modules about hygiene, climate resilience, and local water management.
We’ve already deployed this system in several pilot schools, where it reliably delivers water and reuses up to 60% of greywater, significantly reducing water waste and diesel reliance.
Built with local materials and maintained by trained community cooperatives, the system is low-cost, modular, and scalable. It not only addresses basic WASH (Water, Sanitation, and Hygiene) needs but builds climate resilience by ensuring sustainable water cycles and lowering carbon dependency.
Who does your solution serve, and in what ways will the solution impact their lives?
SunSpring Hubs serve underserved rural populations in Sri Lanka, with a focus on children in public schools, women-headed households, and water-insecure farming communities. These groups are among the most vulnerable to water scarcity and climate instability.
In our pilot schools, students previously had to carry water from distant sources, leading to absenteeism and health issues. With our solution, they now have on-site access to safe, clean water, improving school attendance, hygiene, and overall well-being.
The greywater recycling unit allows schools to reuse water, reducing demand on groundwater and teaching students about circular water use. Community members are trained to maintain the system, empowering them with green tech skills and ownership.
Women — often responsible for water collection — benefit from reduced burden, while local youth gain hands-on experience in sustainable tech. As the hubs expand into nearby households or farms, they enable climate-smart water access and local water stewardship.
Ultimately, our solution provides more than water: it delivers dignity, education, and resilience in the face of climate change.
