Okay, the house construction is almost done at the pond and we have come up with a situation that I need advice on.

We have a sub pump that runs hourly and we need it to drain to the pond. we don't want it on the surface for fear that it will freeze and back up in the winter. The thought we had was to run it underground below the frost line and have it go through the side of the pond so that it pumps under the ice and frost. When it comes out of the house it will be at grade, and then drop under ground. The pond level is about half way up my basement wall, so there is not a big drop from the house to the pond.

The questions are: 1) does this make sense? 2) how do you dig a trench for a pipe and breech a pond wall in a pond that I cannot lower without the trench flooding? If you look at the picture below, the location is in the bottom left corner of the house to the pond.
