This is definitely pushing it. Blackwater is a totally different ball game
and you diligence in design and construction must be much more.
There are a few systems in the table in Create an Oasis with Greywater on
pages 10-11 which are noted as being potentially capable of handling
blackwater. Subsurface distribution is definitely required.
You might also consider giving it its own mini system so if the gws
overloads it won't be spewing blackwater out along with it.

Good luck!
