THank you for this. Very interesting stuff. I mean, I can see local county's point, if they have no sewage where are they dumping their waste? Onto the property? We know that's not good for a myriad of reasons. But the whole state to not allow RV living at all seems dumb.
Actually, most folks compost sewage off grid anyway. Most folks I know RVing or camping use composting toilets anymore anyway, too.
On a homestead scale, that's a 4x4 cube of pallets (or the like)... You dump the honey-bucket in it and cover with some kind of carbon-based... generally sawdust or straw. Done properly, it doesn't even stink. In about a year, that cube is full. Repeat 3 times.
In the third year you can clean out the first cube, because it's all gone to dirt. There are some that caution that prions might survive the composting process, so it is generally accepted practice not to use the compost on your gardens, but around fruit trees is alright, or dump it in a manure spreader and spread it on your fields.
That's a pretty environmentally sound method, very much the same thing as deep-bedding livestock. And it is probably better for the land than the sewage plant.
