big green sewage machine

This is not a "sewage machine", as that would imply the machine processes sewage somehow. Instead it is an emergency generator, according to a couple of guys who were working near it from Charleston Water Systems (the owner of said generator). I neglected to ask, however, what the generator was for.

Yep. I asked another couple of guys from Chas. Water Systems, and they confirmed that it was indeed a lift station.

This also explains to me how a lift station can run into the hundreds of thousands of dollars.
