Because it's simpler to build siphons through large valleys instead of 100 meter high 10 kilometer long aqueducts.

But you have to keep water pressure throughout the length of that tube, how did they do that with their materials?

There is no additional pressure besides from the height/drop, so unless so have a substantial leak where you lose a lot of water, it "just works".
