There was a time when houses built with septic tanks or cesspools had dry wells for the so-called gray water. There also was a time in the South when the laundry was done on the back porch and the used wash water was used to scrub the porch and the rinse water either went to rinse the porch or went into the garden. Up in West VA, john drains his laundry line down the mountain below his house and the water rarely makes it more than 2 or 3 feet before disappearing into the ground. My soil is very porus. I think I am going to have a small hole drilled through the back wall over the laundry sink in the Spring. I will place the submersible pump in the sink and pipe the rinse water outside. I have one such arrangement near where I have the KA, but I don't use the top loaders much at all any more and the FLs are all on the back wall. The only hesitation I feel about this is not moving enough water through my sewer pipe to get stuff out to the street and having it get constipated. I guess I can put those enzymes in my toilet to start dissolving organic matter as it makes its way to the pipe under the street. As my little cousins used to say before their mother flushed, "Bye-bye, doo doo."
