One reason that people didn't pump for a long time is that they (ALL members of the family, even the kids) thought about what went down the drain.

Grease from cooking didn't go down the drain. There was no such thing as a garbage disposal. Toilet paper was single ply, not double ply. Showers were not long, dishwasher? Yep, either the kids or the mom - not a machine that ran for 1.5 hrs. One side of the sink had soapy water, the other side was for rinsing.

Less going in the system, less needed to come out.
