Some parts of Southern California already "close the loop" to a certain extent by using treated wastewater for irrigation. They will partially treat wastewater to a degree that it's usable to eg. water landscaping and distribute it using a parallel water pipe system.
I just meant that in some other place (probably other countries) it's pretty normal to water your plants with at least gray water. Probably not the sewage itself; I don't think human poo makes great fertilizer.
The standard way is to get fresh water from reservoirs and ultimately dump wastewater into the ocean, whether they treat the wastewater first or not.
I don't think it's common to have the system looped. Nature does that on its own.

Now that a lot of people do . Again whether they treat the water first is the question...
They do treat it. I remember reading that it's drinkable in the sense that it's sterile and won't harm you, but it tastes salty.
