No concern about possible black water mixed into the gray tank/lines?
Do you worry about the grey and black water mixing in a sticks and bricks residence? It all shares the same drain pipes and vent system.
In the past many areas allowed grey water to be dumped on ground, where it could be used by plants. But going back forever, one of the first signs of "civilization" was control of human waste. (A century ago, for many homes the control was just a pit, with small building with hole in floor.)
In the modern home, all the waste water goes out the same pipe. The less dirty water helps carry and break down the solids. (We have all heard of the issues RVers have because not enough water in black tank. Think about how fast that issue would develop in house, where waste must move a long ways. Notice when you go to dump station they mix back together?)
It has been a while since I have been anyplace dumping greywater out of RV on ground. I suspect it has a lot to do with understanding what drains from a kitchen sink is pretty dark.
I have heard talk about RVs no longer need 2 waste tanks.
OT. The house where my draft notice found me, toilet, bathroom sink, and Grandma's bathtub drained into a septic system. The field was under part of the area around hen house. (BTW, daytime menfolk where expected to use outhouse) The kitchen sink drained to daylight in the orchard, where chickens cleaned the water. The shower in basement drained into the garden.
