Let There Be Water

Israel's Solution for a Water-Starved World (2015.9)


关于本书 About the book

Let There Be Water illustrates how Israel can serve as a model for the United States and countries everywhere by showing how to blunt the worst of the coming water calamities. Even with 60 percent of its country made of desert, Israel has not only solved its water problem; it also had an abundance of water. Israel even supplies water to its neighbors-the Palestinians and the Kingdom of Jordan-every day.

Based on meticulous research and hundreds of interviews, Let There Be Water reveals the methods and techniques of the often offbeat inventors who enabled Israel to lead the world in cutting-edge water technology.

本书金句 Key insights

● Water has even featured on the country’s currency and postage stamps. The five-shekel note celebrates Israel’s National Water Carrier, the country’s largest water project, while stamps commemorate ancient water systems.

● Before Blass’s discovery, flood irrigation was the accepted method of watering crops. With this, agriculture commanded more than 70 percent of Israel’s overall water consumption. Drip irrigation, in contrast, saves water while doubling crop output.

● Using SAT systems, sewage can be used to supply a third of the water needed for agriculture. Every year in Israel, more than one hundred billion gallons of water are saved using SAT systems.

● Sidney Loeb, a Jewish-American chemical engineer working in Israel, developed a technique called reverse osmosis. With reverse osmosis, water is pushed through a membrane that causes pure water to move one way while salt molecules move in the opposite direction. This technology was the practical desalination solution for which Israel had been waiting.

● Water plays a central role in Israeli diplomacy, with both developing and wealthy nations.
