ELi5 Why can’t we build massive transnational water pipelines (like with oil) to transport water from large fresh water sources to drier areas?

Obviously this wouldn’t relieve the issues caused by low snowpack and decreasing precipitation, but it could supplement the water used for everyday living or agriculture during times of drought right?

We already do this. The main reason we don’t have giant pipelines running across the country is because there’s usually water much closer to the places that need it compared to the area between where oil is refined/distributed and where it is extracted.

Also the water displacement would harm environments it’s collected from. Most people living by a lake wouldn’t be cool with it being taken from their water cycle to help the people in Vegas.
