Why does aqueduct have to be above ground level?
Major aqueducts feeding Paris in drinkable water are underground, so do NYC
ones.

As John said, it is confusing structure and purpose.
I don't see why waterway=* have to reflect the structure it is runing in.
I would add waterway=pressurised isn't necessarily for the structure (it
can involve both tunnel, pipeline and caves) but for the pressure of the
water.

No, there are tunnels too
It's time to pay tribute to John McClane :
