SODIS

2 04 2009

SODIS, or solar disinfection of water, is a simple, low-cost, and effective method of household water treatment.

The technique can be learned easily and applied by almost anyone, including very young children, the elderly, the sick and the disabled. It works anywhere in the world where there is sunlight – so in other words, unless you are stuck on Antarctica between June and September, you can use it. (And if you ARE stuck in Antarctica in July, you probably have worse problems to deal with – and please let me know what internet provider you use!)
