Sort of, but not really. The water on the input side of your tap is much more valuable than the sewer side.

It's not usable for drinking water, it is usable for greywater purposes. If you've got a septic system, it'll go through that into the local ground water, if not, it'll go into the septic sewer and eventually to a treatment plant, and from there a river.

If it was originally aquifer water, you've taken (likely) high quality water from a diminishing resource and put it in the environment.




Northern California gray water and black water is treated and sent to Southern California as drinking water.

So it depends on where you are.


Is this for real? I didn't know this. Any links?


> and from there a river.

And from there it goes to the next community downstream.
