Groundwater enters the sewer system through cracked pipes, deteriorated joints, and failed connections. Increases treatment costs, causes capacity issues, and indicates structural vulnerability.

Fats, oils, grease (FOG), and mineral scale accumulate inside pipes, gradually restricting flow. Common in commercial kitchens and industrial facilities. Can lead to complete blockages if not managed.

Complete or partial pipe collapse blocks flow entirely. Often the end-stage of untreated corrosion, cracking, or external loading. Requires urgent intervention to restore sewer or water service.

A section of pipe sinks due to soil erosion, poor compaction, or ground settlement, creating a low spot (belly) where waste and water collect. Causes chronic backups and accelerates pipe deterioration.

Pipe sections shift out of alignment at joint connections due to ground settlement, soil erosion, or poor original installation. Misaligned joints create turbulence, catch debris, and allow infiltration.

Pipes develop cracks from ground movement, freeze-thaw cycles, traffic loads, or aging. Cracks allow infiltration, exfiltration, and can lead to complete pipe failure if left untreated.

Internal or external corrosion degrades pipe walls, reducing structural integrity and water quality. Affects metal pipes (cast iron, ductile iron, steel) and concrete pipes exposed to hydrogen sulfide.

Tree and plant roots penetrate pipe joints and cracks, causing blockages and structural damage. One of the most common sewer problems in residential areas with mature landscaping.
