UpWater is developing an innovative point-of-use water treatment device called SODIS X, along with an educational program and sustainable distribution model. SODIS X uses sunlight to quickly disinfect water, and field trials in rural Thailand found it was effective and that over half of participants continued using it. UpWater combines this product with social programs to raise awareness of water quality issues and promote behavior change, and a market-based approach to local production and sales in order to provide sustainable access to safe drinking water.
