WaterGreen is a solar-powered, modular desalination system designed to provide safe and affordable water where it is needed most. Operating without membranes, high-pressure pumps, or chemicals, the system runs entirely on photovoltaic-thermal energy and consumes just ~2.2 kWh/m³, making it cheaper and more sustainable than conventional off-grid RO systems. Each WaterGreen unit can deliver 1 m³/day—enough to supply 60–70 people with WHO-compliant drinking water—and is scalable up to 1000 m³/day for larger communities and cities. Its hybrid solar design integrates thermal and electrical energy with smart controls, enabling 24/7 autonomous operation and long-term reliability Beyond technology, WaterGreen is built with equity and inclusivity at its core. By bringing water directly to the point of need, it reduces the burden of collection—especially for women and girls—and enables local ownership and job creation across skill levels. Current pilots, such as our partnership with Water Compass in Uganda, will validate performance and deliver immediate benefits to off-grid communities. WaterGreen represents a new benchmark in sustainable desalination: affordable, energy-independent, and scalable. It is designed to solve water scarcity one container at a time—transforming access to safe water for vulnerable populations worldwide.This is where innovation becomes essential. There is an urgent need for low-energy, decentralized desalination systems that can operate sustainably and autonomously in the field.
