1.2 billion people have no access to safe drinking water resulting in 2.2 million death every year in developing countries. Water scarcity forces people to rely on unsafe sources of drinking water. “Poor water quality increases the risk of diarrhoeal diseases including cholera, typhoid fever, salmonellosis, other gastrointestinal viruses, and dysentery. Water scarcity may also lead to diseases such as trachoma, plague and typhus.” 

Solar Funnel is designed for easier and more efficient SODIS in developing countries. SODIS (Solar water disinfection) is a method of disinfecting water using only sunlight and plastic PET bottles. Exposure to sunlight has been shown to deactivate diarrhea-causing (pathogenic) organisms in polluted drinking water with the help of UV-A (wavelength 320-400nm) and heat.
