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

    Speculating, but maybe a runoff pond/detention basin?

    Looks like the asphalt slopes toward it which would direct stormwater into it. 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.

      Or for propane tanks. They need to have an area underneath to catch the gas if they star leaking. And the bumps can be some kind of foundation for putting the tanks. It looks like it could hold two tanks next to each other.

        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.

            It looks DIY, so I’m willing to accept the ladder. The humps are a bit of a mystery, but from the look of the dirt between the asphalt and the pond, I can see them being sediment buildup from the runoff. Not sure why they’re in those configurations, though, but that’ll have to remain a mystery for someone else to solve lol.

              Probably just ordered too much gravel and put it somewhere and ended up with the humps. I agree though, looks very DIY.

        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.

    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.

    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.

    Could be a hog house sewage slurry lagoon, I see what looks like a pump out on the far right corner. I’m not sure about the humps on the bottom, but they might control the current to avoid a whirlpool effect when pumping out the pond. Just guessing here.

      This is almost certainly it. I agree those lumps on the bottom look intentionally designed to prevent sloshing when filling the pond

      Yep it’s a slurry lagoon aka as a stinking shit pond. Since it’s unlined it leaks massive quantities of nitrates into the soil and water table.
