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.
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.
Speculating, but maybe a runoff pond/detention basin?

I was thinking the same. It looks like gravel.
