Since most of the people who make up the sanitation codes and building codes have taken control, we aren't allowed to re-use our gray-water in most cities/counties/states. They've decided that gray-water is more toxic than sewage, so we can't have our sewer separated from the gray-water. When I was a kid, in the '40's and 50's, we ran the gray-water direct to the gardens and fruit trees - and no one ever seemed to get sick from it ..... amazing what new technology and a college education can destroy! I like your idea of using reeds to clean that water ..... if I could grow a garden here, I'd cut into my sewer pipes under the mobile home and I'd use the gray water to feed the garden and grow cat-tails in my back yard! Cat-tails are good eating, kinda like a cross between onions and garlics, as I remember. I could get away with that here, we only have a little over 100 people in town!Originally Posted by head rush
