It is called SODIS and this is how it works: get hold of a transparent plastic bottle. Wash well before first-time use. Use PET plastic bottles rather than PVC.

Fill the bottle three-quarters full with water from a local water source such as a stream or a river. The water should not be muddy. Shake to aerate the water – the dissolved oxygen helps in the purification process. Then fill completely and screw on the tap.

Place the bottle on a corrugated metal roof in strong sunlight for one full day. The heating of the water and the Ultra-Violet radiation together destroy the micro-organisms which cause water-borne diseases.

Pour into a cup and drink up!

Try this for yourself, as an act of solidarity with those who have no alternative.

Then share the technology with others.
