Our waterline is 2 ft. deep. We are in Tennessee with a 12" to 18" frost line.
Regarding the diameter of your water line, having a larger dia. pipe than the 3/4" at the filter will make a difference if your waterline is long. Smaller diameter pipes will have a significantly higher coefficient of friction than larger pipes. The result can be lower water pressure for smaller pipes when you are running water. Yes, a 1 1/2" or 2" dia. pipe will give you better water pressure than a 1" pipe on a long run, even if the pipe at the water filter is only 3/4". I was a nuclear power and steam plant engineer in my former life so I know a little bit about fluid flow.
That being said, we ran a 1" water line 250 ft. to our garden and without water pressure issues. If I were running a 700 ft. long waterline, I might consider making the pipe a little bigger. My dad has a 500'water line running from the city water line to his house on basically level ground; his water pressure is not great. I think his waterline is 3/4".
I'm sure you will enjoy the new waterline. I'm amazed the original line was only 3" deep.
