Reply to comment by Kytyngurl2 in U.S. Streams Are Drying Up. Data showed that in the South and West, streamflow droughts got longer between 1951 and 2020, regardless of threshold. Worse yet, droughts in these regions are becoming more intense by Wagamaga

In most (non-septic) US households at least, the drains and toilets all go to the same place. I don't think you want to recirculate that for flushing, the result won't be much better than letting it sit.

Most of the smaller 1.5" pipe drains (sinks, tubs, washers) make their way under the house via PVC networks until they connect with larger 3" and 4" drains used by toilets. You could reroute just the shower drain on millions of homes to a tank and a small put could feed it back to toilets. It would never mix with raw sewage. It wouldn't be reasonable with homes built on a slab, you could still do it pretty easy on millions and millions of homes, apartments and such. That would save millions and million of gallons of water.

How about instead of replumbing houses and apartments we get rid of lawns and golf courses in deserts. Maybe not farming in a desert is a better and easier solution.
