Thanks for that! Was it plumbed into a pressurized supply?
the supply was gravity fed from a tank up a hill. never measured it, but based on my best guess at the altitude change, it was probably in the vicinity of 15 psi or so.

could you share more about your system, are you still using it?
I am not still using it. it was pretty simple to build, though. layer of wood chips, spiral of poly pipe, layer of wood chips, spiral of poly pipe. I sprayed water on and stomped each layer.
we used it to heat bath water, which I don't think is the best use for something like that. because it is constantly producing heat, it would be much better for something that also needs constant heat. running the hot water through a radiator to heat a living space, for example.

the only real problem I ran into was finding enough material to build the pile.

We have compartments that hold two buckets, and when the two buckets become full of both pee and poo (and shavings), then they go outside and are replaced with two more buckets. When I have ten full buckets (once a week) I open the pile and dump them. Here is a link to a video of the dumping.
We also do a lot of research and policy work around such things, and have been able to legalize the bucket system, and have even built one at a local regional park, where we also service them. Neighbours bring their friends by just to look at the bathroom... and again no smell. The research and analysis on the compost allows us to safely ensure we can use the composted materilas on the food gardens, as well as hen I do a presentation to schoolkids or engineers, I can let them handle and smell the compost.
One key point, if you remove the urine from the bucket, you are removing the nitrogen from the system, and the composting process is less vigorous and the end product is nitrogen deficient (as studied at UBC Choi toilets that do separate). The course we teach on grey water and composting toilets has one common point... if it smells then your doing wrong - neither should ever smell.
In our home we run a 24VDC 50cfm fan which keeps the slightest of air flows through the toilet compartment - this also seconds as the bathroom exhaust fan, as well as services the whole house's demands under the building code to meet the required air changes per hour. Don't be nervous... trust what Joe Jenkins has written... everything goes into the bucket and give it plenty of cover material, more if it seems sloppy. My fovorite time of the year is when I dig into my 2 year old pile and place it in the gardens. All exciting!

I will admit my cats do eat a lot of birds..which I do frown upon..however..we still have lots of birds..
Actually do believe that my big cat would eat chickens if i had them, that is why I don't..he eats rabbits and anything smaller and when he was about 6 mo old he took down a fawn..or tried to..but we didn't let him keep the fawn. (he was just playing, he wouldn't have eaten it)
