• Advantages of SODIS compared to common treatment
  methods
• SODIS saves your time, less work than boiling
  water.
• SODIS does not change the taste of water unlike
  chemical products.
• SODIS saves your money once you are using SODIS
  consistently and correctly you will not need to
  spent money on diarrhoeal medication and fuel.
• You can use your SODIS-bottle for storing your
  drinking water.
• The re-use of plastic bottles keeps your
  environment clean.

?There is no cheaper way to treat your drinking
water! ? There is no more environmental friendly
treatment method! How can you save money on
chemicals, fuel or electricity and keep your
environment tidy by recycling plastic bottles at
the same time?

• How to use SODIS
• Wash the bottle well before the first time you
  use it.
• Use the cleanest water you can get. If your water
  is dirty leave it in your bucket for some time to
  settle it down. Use a clean cup to fill your
  SODIS-bottle and leave the residue at the bottom.
• Fill the bottle ¾ full with water.
• Shake the bottle for 20 seconds.
• Fill up your SODIS-bottle completely with water
  and close it. Only a small air bubble should be
  seen after turning around the bottle.
• Lay down your SODIS-bottle in the sun, e.g. on
  your roof.
• Leave your SODIS-bottle for at least 6 hours from
  morning till evening in the sun. If it is cloudy,
  expose your SODIS-bottle at least 2 days to the
  sun.
• The water is now ready for drinking.
• Keep your SODIS-bottle clean. Replace your bottle
  when it got too many scratches and is not clear
  any more.

What is SODIS? SODIS is a water treatment method
which uses the sun and means solar water
disinfection. For SODIS you need a transparent
PET-bottle, e.g. clear juice bottles or the
bluish mineral water bottles (max 2 Litres).
After filling this bottle with water you place it
in the sun for at least 6 hours. UV-light and
heat from the sun inactivate the micro organisms
(bacteria, germs, pathogens), which causes
diseases like diarrhoea.
