At the risk of beating a dead horse I would like some advice.
I am building a new home that will incorporate a grey/black water waste system.
I have been using a septic tank for over 12 years with no problems, so my question is this: Would you classify the water from a final print washer (after selenium toning, rinse, PermaWash or KHCA and a rinse) as grey or black?
I lean toward grey, GF leans toward black.
Thanks in advance,
