It has always amazed me that we have oil pipelines crossing entire continents. But we can’t do the same for freshwater. Somewhere is always flooding and somewhere else always needs water, seems like a big ole pipe or three could solve this.

People do build water control megaprojects to route (canals, aqueducts) and store freshwater (dams and reservoirs) and to prevent flooding (levees, dikes, etc). Cross-country aqueducts are just hugely expensive and generally don’t move enough water to be worthwhile.

Continents is a bit of a stretch, but we can and have done this in the past just like with oil. Look up the Great Man-Made River project in Libya, which supplies freshwater from deep in the desert aquifers to cities along the coast, or the LA’s multiple aqueducts which supply water from various sources hundreds of miles away. There’s also the Goldfields Water Supply Scheme, which supplies water from the coast of Australia inland.
