To take advantage of the constant temperature of the ground below the frost line. While it is freezing above ground...beneath the ground maintains an average temperature of 75%
5.6 feet below ground level.
Possibly a broken water line below the frost line or under ground water seepage also below the frost line as the ambient temperature of the structure can act as an insulator
the maximum depth of ground below which the soil does not freeze in winter.
frost line in pa is 42 inches
