The sewers I’ve seen in TV and cartoons makes it look like the house pipes all dump into one big tunnel, with a river of nasty just kind of there. What’s happening to move/process everything?
Yeah, it’s pretty much a big tube of awful. But it moves just like a pipe drains water into a storm drain. Things move via gravity until they hit a pumping station that provides pressure to get up over hills and gradients and into treatment facilities and such.
