Using solar-powered ultraviolet (UV) technologies, 1001 fontaines pour demain establishes water purification and distribution networks in Cambodia’s rural villages, allowing people to meet a basic need for a minimal investment. Unlike conventional potable water delivery, 1001 fontaines’ model incurs no distribution costs and offers the amount of drinking water necessary to match village needs, and thus offers clean, purified water at just $0.01 per litre, which is affordable for rural Cambodian villagers.
