SODIS is a method for producing potable water with PET bottles and sunlight. Water to be treated is placed in clear plastic PET (PETE) drinking bottles and left in direct sunlight for at least six hours. UV radiation from the sun will sanitize the water. The end user only needs to follow the three step process to produce satisfactory results. No tests or precise measurements are required. The SODIS method is intended to be used in developing nations where the situation calls for small-scale water sanitation at very low cost.
SODIS was developed by Eawag, The Swiss Federal Institute of Aquatic Science and Technology. EWAG continues to fund research in SODIS but funding for user education must come from private donations.
