Thanks for the ideas -- I guess it WAS pretty obvious that the first step would be to take the whole procedure out in the garden. That way, the water doesn't get wasted down the drain. Whether I use the perfectly good "dirty" water intelligently or not, at least it goes right back to earth.
I like the garden sink idea -- I'll have to give it some thought. One of the searches turned up a home made filter made of a large clay pot filled with sand, gravel, and small stones that fits on the rim of a 5-gal bucket.
Too bad we got rid of that old stainless steel kitchen sink a few years ago... but someone's created a birdbath out of a pedestal sink... or maybe a glazed ceramic pot (with a drain hole)? This will be a fun project!
But for now, I guess I WILL just use what's available and wash outside.
As for " Anything that makes it through you were destined to eat... "
Try telling that to my 7 yr old! If she spots a speck on her glass, she declares it "dirty"
I do agree about the microbiology thing.... There's too much emphasis on the hype to "kill/eliminate 99.9% of germs" I think we're brainwashed into thinking that doing this is somehow healthier.
