As a side note, I like that this Ted Talk addresses that water shortages do not lie (solely, you should still take shorter showers) on personal responsibility, that only 8% of water usage is domestic, while 70% is used for agriculture and 22% for industry, and that that needs to be addressed. It straight up says that "profit is not the same thing as the common good."

But if we are talking about individual responsibility, and city/local government responsibility too, you know what takes a LOT of water?
