re: What Kind Of Septic System Do You Have?
House is on a septic system. However, I have installed an "Envirolet" low-flush remote composting system in the barn for the horse boarders.
It is rather unique in that it combines a Dometic porcelain marine vacu-flush toilet with a remote electric composting unit which is located in another room. No compost smell because the toilet flushes with water. The vacuum/macerator unit discharges into a composter instead of a holding tank, as it would on a boat.
The riding horse boarders, all women, love it because it is more like a conventional flush toilet than those rather unpleasant composting units that you sit on top of. This system was not inexpensive though.
