I’m purchasing a property which will not perc for a conventional septic system. There are alternative septic systems that are possible, but also I’m wondering, what about an alternative system altogether? Does anyone have experience with handling greywater and waste separately (say composting for waste) in a home with several members?
Urine diversion dry toilets (UDDTs) exist, but if you are in a hot but humid climate they can be a bit bothersome.
In general, composting fresh human feces is a bit risky as you often can’t control the temperature sufficiently well.
In general a multi-chamber septic tank with a horizontal flow constructed wetland works fine and is very low maintenance.
