The acre-foot is a non-SI unit of volume equal to about 1,233 m3 commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, sewer flow capacity, irrigation water,[1] and river flows.
Haha. No, I looked this up just 2 minutes ago, but what a coincidence, huh? 🤣
Crazy that the top is over 5 times more than the next one 😮. The largest outflow in North America and the one I've seen in person is the Mississippi, which is only 9.5% the outflow of the Amazon. The Amazon is over 10 times more than the Mississippi, which I thought was humongous in person 😮.
On to sewers, which is what one of the uses for the acre-foot according to your quote. The following is a list wastewater generated by location:
Location
Generation (ac-ft/s)
Asia
5,073.6
NA & Europe
2,124.6
All 3 Continents
7,198.2
So the outflow of the Mississippi alone is greater than twice the wastewater of Asia, North America, and Europe combined 😮!
