Composting Toilet

Originally posted by gpokluda Dumping gray water is actually legal in most states, of course there are restrictions and caveats so best to consult local laws before doing so. New Mexico, for instance, allows 200 gallons of gray water to be discharged without a permit. BLM usually allows gray water dumping on surface but National Forests and Army Corps of Engineers do not. Best to know your options.

Here's an article written after some research on grey water dumping by Boondockers Bible.

That being said, I once dumped an almost full black water tank on the highway when the factory (reinforced) hangers (yes, two of them) broke. The end dragged and the valve opened. I had to replace the valve and I now use a heavy muffler hanger to hang the pipe. There won't be a third time if I can help it. I am very glad I wasn't behind the trailer. The only thing was it was a hot summer day with lots of sunshine, so I hope the UV rays in the sunshine killed any bacteria quickly. I feel sorry for anyone who was back there. I did not even know about it until someone passing flagged me and let me know there was a problem. I did not know what the problem was until I got to an exit and pulled off though.

Check your tank hangers. A composting toilet (to get back on topic) would have helped avoid this situation as there would not have been a tank full of nasty stuff in the first place.
