It’s still a stupid idea. Taking the runoff from a mountain and pumping it thousands of miles is more expensive than getting water from natural aquifers locally. Heck, even building a local desalination plant and turning saltwater from the city’s coast is cheaper than this giant pipeline idea. There’s a reason NYC doesn’t need to build a pipe all the way from Niagara Falls.
It’s the faucet he read about on truth social, which means it’s real. There was even a picture of the faucet, and we all know those can’t be faked. /s
