Nashville sits on expansive clay soil that swells when wet and shrinks when dry. This constant movement exerts lateral pressure on rigid underground pipes, particularly old galvanized lines that lack flexibility. During winter, our temperature swings from 25 degrees at night to 55 degrees by afternoon create freeze-thaw cycles in the top three feet of soil where most residential service lines sit. Water inside the pipe freezes, expands, and cracks weakened sections. When it thaws, you get catastrophic failure and flooding. Add in the limestone bedrock common in neighborhoods like Forest Hills and Oak Hill, and you have pipes pinched between shifting clay above and immovable rock below. This combination makes emergency water main repair a frequent necessity across Davidson County.
