According to statistics stomach problems are one of the most common things that makes people in Tatum visit the health centre. Stomach problems are often caused by bad water and sanitation.
One way to reduce the risk of becoming ill is to treat water fetched from rivers and springs before drinking it. This can be done by the SODIS method.
The bacteria’s in the water (the ones we want to get rid of) are deactivated by the combination of heat and UV-radiation. Since the bacteria are only deactivated and not killed the water should be consumed within the first 3 days. If not, there is a risk that they might wake up. If the water has not been consumed within 3 days you can redo the procedure and the water will be drinkable.
How to do SODIS
1. Get a transparent PET-bottle and remove the label.
2. Fill the water with water (the water cannot be too brown, you should be able to read a newspaper headline through the filled bottle).
3. Put the bottle facing the sun, for example on an aluminium roof.
4. Wait. After 6 hours it is ready for consumption, if it is cloudy the bottle might have to be in the sun for 2 days in row.
A way to further increase the efficiency of the method is to fill it to ¾, close and shake and then fill the rest of the bottle before putting it in the sun.
When families in Tatum using the SODIS method were interviewed they witnessed about improved stomach health and a majority of the interviewed said that they had not had any stomach problems since they started with the method.
