In the event of snow, stay out of heavily wooded areas as trees are more prone to failure when soil is very wet and branches are weighed down with snow. WebA water line should be buried 4-6 below the lowest depth of frost in the ground so that it doesn’t freeze and burst. The lowest frost point varies based on your climate and the quality of your soil. Call 811 to make sure that there are no cables, wires, or sewer lines in the ground so that you don’t damage them when you bury a water line.
