Yes, blackwater is that dangerous. I don't know what has gotten into
your local environmental people that they could think of using septic
tank effluent on strawberries!
I suggest you get a copy of Oasis greywater-book. It
includes health guidelines which explain the mechanisms of contamination
and purification which would help you understand exactly what it is
you're dealing with and how you can continue to flirt with disaster
without becoming engaged in it!
There are also a few greywater systems which are described as being
capable of handling blackwater, and others which I would not publicly
recommend but would recommend to a bold individual such as yourself.
