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?
Are you trying to be permitted by the county/local gov?
It’s definitely possible to do graywater separate and compost human waste. I’ve done composting in the past and it can work great. But getting the county (I’m from the US) to sign off on it is really depends on your local government.
One great resource in general is the The Humanure Handbook By Joseph Jenkins
Yeah, a composting system may not be allowed by the county. Unfortunately it seems fairly rare in the US for these systems to be permitted, and my county defers to the state on this. I’ll need to do more research there.
