The 3 barrel composting system has been approved since 2005. You can use a smaller septic system to accompany the 3 barrel composting system. Check out Jim and Jessica at the Green Dream Project's GREENSTEADERS - Homesteading, Off Grid, Permaculture.  They are here in Cochise and have an alternative septic system just for their kitchen sink water but you can use it for shower water also. They also have a YouTube channel.

Did you hire a structural engineer to help you with the design process including help with determining the size of the posts and beams, site selection (land and soul quality), safety
inspection, and dimensions or did you perform everything independently?
