— WITHOUT WATER

Solar water disinfection is a method of disinfecting water using only sunlight and plastic PET-bottles. It’s simple and easy: filled a transparent PET-bottle with contaminated water and exposed it to the sun for several hours.

The water must be relatively clear, and the bottles must be clean and unscratched. This method is recommended by the World Health Organization and approved by UNESCO for being the simplest and cheapest water disinfection system.

Because nearly 70% of an adult’s body is made up of it and 1 billion people lack access to it.

Because about 2.5 billion people don’t have improved sanitation facilities and half of the world’s hospitalizations are due to it.

Because 1.4 million children’s die each year form it and every 20 seconds a child die from it.

WATER MUST BE A PRIORITY!
