This is similar to, but more general than this question and referring to from scratch buildings.

I've seen Create an Oasis with Greywater and it's an awesome resource to build a DIY system.

The question is, how are new homes built from scratch that are trying to reduce their water impact doing all this, while remaining comfortable and usable by everyone? Can you point to existing systems used to build new homes that are just as comfortable as regular homes but that reuse the greywater?

  • You mention homes -- are you interested specifically in single family, or multi-family homes? Or just in general?

    I was thinking single family when I wrote the question, but either or both are fine by me

  • I'm realizing this question is a bit broad -- I'm wondering exactly what you're looking for? Product recommendations would be off-limits. Also, why would a gray water system be less comfortable? Sounds like maybe you have a particular challenge in mind.

  • I think greywater use would be for the toilet or for the yard or for a root irrigation of a shade tree in a desert climate. For the toilet, a toilet-bowl-cleaner with bleach in it works very well and that's chlorine.

  • Yeah, my water bill is more than the electricity bill so pump the shower and sink water into an overhead stainless-steel tank that refills the toilet-tank. Turn the water pressure line to the toilet-bowl as off. But rainwater from the roof could work without pumping. And basically, the stainless-steel roof is clean after the first few minutes of rain.
