Answer 1

They used a very very big boat

Answer 2

Answer:

Aqueduct Engineers used "pressurized pipes" to move the water through the deep valleys.  With the use of siphons, water travels down one side of the valley in pipes. Water pressure forces water up the other side. Water exits the pipes at nearly the same height as it entered.
