Digging used to be much more expensive, and calculating pressure much dicier. The Romans used the pressure method over short distances, with reliable piping (noting that pipes under high pressure would need to be sealed with earth or concrete), but over large distances, it was easier just to make a giant-ass water bridge and ensure it was sturdy.

There goes my mind again, sliding that dash sideways.
Plumbing engineer here. Digging is still fucking expensive.
I dug like an 8 inch hole next to my walkway the other day and it took like 5 hours and I didn’t accomplish what I wanted.
