Judging by the infrastructure, I can see large vats on the exterior, I can assume it used to be an old water treat,met plant, purely based on the tanks/vats, location, infrastructure, etc it could have also been a sewage treatment plant or a chemical treatment plant, but, with both of those, the location doesn't exactly match up to that, but, it being a water treatment plant makes more sense as they would ship out the water via trucks (much like the tanker trailer) to the local corner store, where a sewage treatment plant would be useless, as there wouldn't be enough demand for even a outflow pipe, and, a chemical treatment facility would also make little sense there are little aids for such a facility in the middle of nowhere, so, likely a old water treatment plant closed down due to lack of demand and customers, unsustainable sources of water, or lack of employees able to access a remote area as such... Devs, if I got this right, I deserve a medal...
Well, since its rusted, it must be metal. The section in the back looks sorta like an office building tho. My dad says it looks like an ore refinery.
Their alien technology could use it to broadcast signals into our heads! Take me off and burn em! Put on your favourite Epsilon Program suit, we are doing this GTA style!
I'm 100% someone asked this question somewhere on the forum. About question - this is abandoned Tintic Standard Reduction Mill.
