Was chatting with a guy at the feed store last month, he runs a cabin up near Flagstaff. He said he just pipes his shower water straight into a buried 55 gallon drum with gravel, then lets it seep out to some willow bushes. I always thought greywater meant fancy filters and pumps, but he broke it down so simple I felt dumb. Now I'm redoing my drain line this fall, anyone else run a soak pit like that or do you filter more before it hits the ground?
