Adding a line from my existing well to a cabin

I have a 180ft. well with 40 feet of sand for filtering. There are 3 of us in the home. Can I add another line to feed into a one bedroom cabin? The cabin would be about 150 yards away from the well but my father's well is about that far too from his home? My well is 12 years old and no problems and live on the water. Help.

As long as there are no check valves above ground, you can tee in just about anywhere. Just make sure to use large enough pipe that you don't lose all your pressure before the water gets there.
