How Do Desert Cities Get So Much Water?

Millions of people live in cities surrounded by desert. So where does all their water come from—and what does it take to keep it flowing? In 2022, Lake Mead fell so low that one of the pumping stations supplying Las Vegas could no longer operate. Yet the city kept receiving water. The reason had been years in the making. This documentary follows the water systems behind Las Vegas, Dubai, and Windhoek: deep tunnels beneath a shrinking reservoir, desalination plants that turn seawater into freshwater, and treatment systems that bring used water back into the drinking supply. But finding water is only the beginning. Pumps, hidden leaks, energy, and the journey after the drain all help determine whether a desert city can keep its taps running. Which part surprised you most: Dubai's desalination, Windhoek's water reuse, or what happens after water goes down a Las Vegas drain?
