Any recommendations for the size of the trench that needs to be dug to accept the channel?

Go to NDS's website. There are full installation instructions.

How long are these sections and can they be connected together for external lenghts?

The sections are 39 3/4" long. The ends are designed to slide together to allow for long lengths.

Can this be used for old construction or new only

I used it for a new drainage project. I would guess that it could be used for an existing system as long as you could connect to the 4" discharge port on the end of the unit
