Has anyone made a filter to make gray water better for the environment?
I met a TT camper a few years ago that had a two step filter he used. The first was a PVC device filled with sand the second was a filter unit used for lawn sprinklers. This he had filled with activated charcoal. According to him, when he was done filtering he put the sand and charcoal in the fire pit and the fire took care of the filtered badness. He said it filtered slowly but the water was clean when it came out. Seemed like a good idea.
