How does that siphon work? I would think they would need a pump of some kind, even if it's just a bunch of Roman workers/slaves turning an Archimedes Screw, to get the water to go uphill.

Same way a fuel siphon works, as long as the opening is below the inlet, and the rest of the tube is full and sealed, the water will flow.

It never would have occurred to me that siphons work that way, too!
