SODIS

SODIS, is the acronym for a water-disinfection method developed by the Swiss. I read about it recently in the latest National Geographic magazine, which is devoted to the water crisis brewing all over the world. Basically, the way it works is you fill old water or soda bottles with untreated water, then put them in the sun for 6 hours. The UVA radiation kills viruses, bacteria and parasites, making it safe to drink. It really works and cost essentially nothing.

It is so cheap almost everyone can afford it but it is still a bit of a hassle to go and get, and then transfer it to smaller containers for everyday use. Our tap water comes from our well and is filtered but we don't drink it. We just use it for bathing, dishes and laundry. Using the SODIS method, I plan to treat the tap water and use it for drinking. I'm not saving a lot of money, mostly just time, plus I just think its such a cool idea.
