I have a truck dock area at work. It has a drain with a manhole cover. But the drain does not drain quickly because it is a french drain. So, we get a lot of water...up to 2 foot deep which may take several days to drain. If it is cold, it freezes. A real problem with truck deliveries coming every day.

I am thinking some kind of pump, but I have some questions. Do I locate the pump in the pit for the drain or leave it out of the drain on the low point next to the building. If it is out of the drain, I assume that it would have to be turned on manually, which is not an issue. I do not need a high volume pump, but need a pump that may get some minor solids, leaves, etc. And what about the freezing tempertures?

Any ideas on what I should do and some pump recommendations would be appreciated.
