In the long history of global civilization.
Water source.
Is a keyword that no civilization can do without.
The waterwheel and water hammer in Huaxia, and the Archimedean screw pump in the West, are tools created by ancient people for water supply.
But all of these tools, without exception, are huge in size, and most of them need to work at the water source.
And their main use is actually mostly to transport water from low to high places.
Throughout the entire ancient world history, almost no civilization could achieve flat land water transport without relying on gravity.
Whether it's the Roman aqueduct system, which shocked the world, or the Tang Dynasty's water facilities in Chang'an, they are unrelated to flatland water transportation.
For instance, the Roman water supply system was composed of the old Anio aqueduct, the new Anio aqueduct, the Marcia aqueduct, the Tepula aqueduct, the Julia aqueduct, the Virgo aqueduct, the Antonine aqueduct, and so on.
