Social Experiment. Become Me. What I see, you see.
I thought this was already a thing everywhere. Doesn't wastewater go to a water treatment facility, get treated, then recycled back theough?
Usually, it isn’t. What usually happens is that the water is treated, then sent to a nearby body of water. Technically, you are right, but there’s an environmental release of the water before it goes back into the water supply.
