Using a combination of traditional water filtration methods, as well as generating purifying ozone via a solar source, water from just about any source can be turned into potable water for use in cleaning, cooking and drinking.
In Africa, especially, there are more than 350 million people, and over 750 million people around the world, with no access to clean water. Additionally, over 840 000 people die each year from water borne infections and disease.
This is, of course, highly preventable, but as water purification set ups are generally very expensive, and require large amounts of electricity to operate, I have decided to go a little lower tech, whilst still providing the highest quality water possible.
There should be very few moving parts, or complex electronics, to ensure that the units can be easily maintained by the community itself.
