Most of Israel's fresh water comes from the Kinneret (also known as the Sea of Galilee). A severe drought during the past five years and increased demand for drinking water have caused the Kinneret to shrink to dangerously low levels. In fact, during one week last spring, the lake receded 2.5 inches. Experts worry that by the end of 2008, Israel, which already has one of the world's lowest amounts of available water per person, could face a water shortage of almost 100,000 gallons.

Although it might sound gross, treating and reusing sewage water for irrigation is the easiest and cheapest way to increase Israel's water supply. Aqwise, an Israeli company, is leading a technological revolution that potentially will renew millions of gallons of wastewater that otherwise would be lost. Currently, they clean about 76,000 gallons of wastewater a year while setting an example for the rest of the world in the process.
