The Romans absolutely used this technique.
With lead seals in the pipes and aqueduct.
Geniuses, It took us almost 2000 years to figure out how to get that lead airborne.

He may have killed more people than hitler. Lead is now believed to be a significant cause of heart disease

He determined it could be used as a anti knock additive to satisfy some general motors exec who didn’t want to use alcohol as a ping inhibitor because of? You guessed it, cost
The auto industry determined in the 50’s that lead was a poison. But it took until the 70’s for politicians to do anything about it. prop airplanes use fuel that has lead in it to this day.
What have the Romans ever done for us?
Why did the guy in charge of this use a giant bridge instead of the bottom method? Is he stupid?
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.
giant ass-water bridge
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.
