At a farm in Wisconsin. Farm is big, but looks like it only houses large equipment.

The element that makes me think no one has gotten it right are the stairs. People enter and exit this when it is full.
I am willing to wager internet points that this is for washing or fluid based differentiation of materials. The dividers structure would be some form of flow distribution control or cleanup system.
Speculating, but maybe a runoff pond/detention basin?
Looks like the asphalt slopes toward it which would direct stormwater into it. There’s also no gutters on the building in the back, so that water would just hit the pavement and run off. There’s also a pump-looking gizmo in the lower-right corner that appears to have a discharge hose going away from the structures on the property.
I mean, the steps could be a safety device if you fell in since there’s no safety rails around it. The humps are probably just sediment buildup.
Again, I’m speculating, but I’ve seen those kinds of basins before.
Speculation but: Children.
If you have something that looks like a pool they’ll go swimming.
The ladder gets them out and the humps give them a place to stand in the middle to keep their heads above the water line. Their arms get tired very quickly.
Possibly a slurry pond? The only pools like that I’ve seen on farms were all on dairies; and they dump the cow piss and shit in them. I’ve also seen above ground cess pools like this at some industrial factories in the boonies. Used to be a tarmic plant outside my hometown that used one.
Looks like it would be a fun RC car playground.
