CHALLENGE:  Boiling water is one of the most common ways to disinfect water for drinking. However, it is a very expensive and energy intensive option as it uses fuel and/or wood.

ASD SOLUTION: Solar pasteurization uses the sun to heat water to kill bacteria and other pathogens. Solar CooKits and SODIS (Solar Disinfection) are inexpensive and simple ways to treat water for drinking. 

Solar CooKits can be made from cardboard and reflective material. It can be used for cooking and can save families money not having to buy fuel and/or wood for cooking or boiling. Also, it is great for the environment because it reduces deforestation from wood collection.
