Minneapolis experiences some of the most extreme temperature swings in the country. Winter lows hit negative 20 degrees, while summer highs reach the 90s. That 110-degree annual temperature range puts enormous stress on underground infrastructure. Water seeps into microscopic cracks in your sewer pipe during fall. When temperatures plunge in December and January, that water freezes and expands with tremendous force. The expansion widens existing cracks or creates new fractures. By spring thaw, what started as a hairline crack becomes a separated joint or collapsed section. This cycle repeats every year, progressively destroying aging clay tile and Orangeburg pipe common in older Minneapolis homes. The symptoms of a broken sewer line often appear suddenly in spring as ground thaws and the full extent of winter damage becomes apparent.
