One thing that fascinated me working for a sanitation district was that we had some huge pumping stations like this, but hiding in plain sight.
There would be a metal vault cover in the sidewalk, it opens up to a stairwell, then you walk downstairs to a massive concrete wet well and pumping station under the street.
I had no idea they were even there, but they are, especially in urban areas.
It's a lot cheaper to build them above ground, but they did what they had to to move sewage.
