California is in the midst of a horrible drought and so we've begun using the gray water from the girls' bath to water the garden and lawn. So far, it hasn't killed anything (they use small amounts of soap) and it's fun for us. I suspect our neighbors think we have some serious plumbing problems as they watch the four of us hauling buckets of water out the front door and dump them on the lawn.
I heard an interesting story on NPR today about people who are illegally using gray water from their washing machines to water their gardens. I'm going to investigate further but I wonder -- do you have any advice or experience with using gray water?
