Really?
My father's house went from a two seater out house, to in door plumbing and a septic tank in 1950.
The paper was always flushed and every 5-7 years a honey dipper came and cleaner the septic tank.
He was forced to go to a municipal water/sewage plan in the mid-eightys and forgo his free well water and septic tank system.
Every time he got a water/sewage bill, he bitched about the rotten gummint.
In Soviet Russia, Brown water drinks you!
