The Darley Sunspring is a self-contained, certified, solar and wind-powered, microbiological water purification system that can treat up to 5,000 gallons a day of safe drinking water for up to 10 years. Once installed, the system requires no costly generators, gasoline or diesel fuels. It operates on 100% solar and wind energy. A typical Sunspring installation will not only provide drinking water to the primary place where it is located such as a school, hospital, and orphanage, but can also provide drinking water for the surrounding communities. The Sunspring is the only decentralized solar water plant in the world that is WQA (Water Quality Association) Gold Seal Certified to the US EPA Standard for microbiological water purifiers and validated in part of the GE Healthymagination program. All that is needed to operate the system is access to a fresh water source and direct sunlight.
