Hydraulics

"Siphon Principle - Hero, a Greek who lived after 150 B.C. was the first hydraulic engineer. He modernized the obtaining of water through a method known as the siphon principle. The siphon principle allows the pipes that carry the water to follow the terrain of the land and the aqueduct and bridging techniques were no longer used as often. For example, such a device was used for the citadel at Pergamon. The pipes that connected to the citadel had approximately 300 pounds of pressure per square inch and the pipes were most likely made of metal in order to withstand the pressure." from Science in Ancient Greece
