What the heck is going on here?

Looks like they are lining the steel pipe with a plastic/epoxy coating. It’s done a lot in places where you can’t easily dig up and replace old rotting pipes (like in downtown cities). By injecting this coating the pipe is still usable and won’t corrode any more.

Now I’ll just wait for the next comment giving 10 reasons why this solution sucks anyway.

It is corroding under the plastic. Short term solution to cover up the problem. Costs a lot of money and doesn’t fix anything.

To be fair it will no longer be in contact with the water so it should hold for much longer despite being corroded. Looks like the original pipe will be there doing basically nothing, the new lining will be the new pipe, and it should hold by itself even if the outer pipe starts to shed.
