Just casually throwing in 'overpopulation' when in so many places, water for actual human needs like drinking, bathing and even washing clothes, is a tiny fraction compared to much more wasteful things like grass, America's largest crop.
I live in a dry bit of the American west and municipal usage is a small fraction of water usage (about 8%). Agriculture is often not very efficient because of old water rules that give water to things like hobby farms when real farms downstream don't get what they need.
