Digging your sewer lines to the proper depth is essential for safely and swiftly removing wastewater from your home. In Pennsylvania, the frost line is 44 inches beneath the surface, and any sewer lines installed above this level are at risk of freezing and bursting, causing costly damage.
When it comes to sewer line problems in Pennsylvania, frozen pipes are a leading cause of damage. We recommend that every homeowner verify to determine how deep the sewer lines on their property were placed.
The average frost line depth in Pennsylvania is 44 inches. At this depth, groundwater and any water in your sewer lines will freeze. Generally, the colder a region gets in winter, the deeper the frost line.
During especially long, cold winters, these depths can drop far below what’s considered normal. In addition to changes caused by air temperature, frost lines can rise or fall based on soil type and moisture content.
Not only will water freeze above the frost line, but as it freezes, it causes the soil to heave. This is because water expands 9% in volume when it freezes, forcing the soil out of position. Anything positioned within or above the frost line will shift. This includes building foundations, footings, and of course, sewer lines.
Most communities in Carbon County and throughout Pennsylvania require sewer lines to be installed well below the frost line. This means installing it at least four feet below grade. However, that’s not always the case, and many factors can affect the actual depth of the line, including:
