Solar water disinfection, also known as SODIS, is a method of disinfecting water using only sunlight and plastic PET bottles. SODIS is a free and effective method for decentralized water treatment, usually applied at the household level and is recommended by the World Health Organization as a viable method for household water treatment and safe storage. SODIS is already applied in numerous developing countries. Educational pamphlets on the method are available in many languages, each equivalent to the English language version.

Famous quotes containing the words solar and/or water:
“Senta: These boats, sir, what are they for?
Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
—William Faulkner (1897–1962)
“Instead of water we got here a draught of beer,... a lumberer’s drink, which would acclimate and naturalize a man at once,—which would make him see green, and, if he slept, dream that he heard the wind sough among the pines.”
—Henry David Thoreau (1817–1862)
