I've been considering a co-housing project and one thing we're concerned with is water.
Trev, this might interest you- a complete sewage treatment plant system:

A composting toilet is a type of dry toilet that treats human waste by a biological process called composting. This process leads to the decomposition of organic matter and turns human waste into compost-like material, but does not destroy all pathogens. 😛 🙂
Pro - If you maintain a composting toilet properly, there will be virtually no smell. Con - If your composting toilet isn't maintained properly it can get pretty smelly.
Here's an idea some might like: In my bathroom sink I have a large plastic bowl (a popcorn bowl; the sink has a round basin) to catch the water from washing up. Then I pour that water into the toilet to flush it, so the water gets used twice.
I've been using this workaround for three or four years because the drain pipe from the sink has a leak (in the wall behind the cabinet rather than anywhere accessible), and it's too much money and trouble to have the bathroom torn apart for a day or more to get to the leak and fix it.
Not ideal, but it works well enough. On the other side of the wall I have a large plastic dishpan in the kitchen sink to catch the water (same drain pipe in the wall), and empty that two or three times a day, so that's some exercise as well.

Sounds very innovative to me! So long as you don't get mold from it as you don't know what it looks like in the wall.
