SODIS uses increased temperature, UV light, and oxidative chemistry to inactivate
disease-causing organisms. Users are trained to place bottles in the sun for 6 hours-2
days, depending on climate. Diarrhea reduction is 9-86%. Aside from initial bottles,
SODIS is a zero-cost option. Benefits include acceptability to users because of the
minimal cost and ease-of-use. Also, recontamination is unlikely because water is
consumed directly from the bottles in which it is treated. Drawbacks include the need for
pretreatment of turbid water, limited volume of water that can be treated at once, length of
time required to treat water, and the need to obtain clear plastic bottles. www.sodis.ch
