How Did Ancient Rome Get Clean Water Without Electricity?

You wake up in Rome in 100 AD, and the first thing you hear is running water. No pump, no motor, no button, and the fountain on your street has been flowing since before you were born. How is that possible? This video follows the water back to its source. You'll see how ancient engineers used gravity and a barely noticeable slope to move water across mountains, valleys and deserts. You'll meet the Tunnel of Eupalinos, Persian qanats, the Pergamon siphon, Frontinus (Rome's water commissioner) and the Pont du Gard. Along the way you'll find out why most aqueducts were hidden underground, how water thieves and bribes were a problem 2,000 years ago, and why a city is only as big as its water.
