Yes, I've heard from another friend the people at the County Planning office can be helpful too. I'm planning to go there and enquire, hypothetically at first, what kind of guidelines are in place and what kind of limitations I have. I did download the Alternative Systems Manual, which is pretty clear for composting toilets.
It seems clear that having running water to the "bathroom" would make it more complicated as far as the regulations go. So I might also enquire about a rainwater collection system or something like that for handwashing. We would prefer to have a handwashing sink if possible.
Yes, we will have power to the site, and I plan on having the composting area well insulated, possibly with a light-bulb for heat, so that it won't freeze in the winter. I would like to build my own system, though it sounds like that may be harder to be approved. I'll see what they say about that.
I'm glad Yvonne passed along my card. SHe said she had contacts at Mudd.
