299_largeVideo cameras may be used to identify damage and obstructions that inhibit proper flow or create occasional or repeated backups. The cameras also verify that obstructions have been removed and that the lines are clean following service. The condition of a line typically cannot be determined without a visual inspection using an in-line camera.

Video camera inspections pinpoint problems:

Broken, cracked or collapsed pipe — damaged pipes requiring repair or replacement.

Offset pipe — sewer pipes have become misaligned due to shifting soil, frozen ground, settling, etc.

Blockage — grease buildup or a foreign object is restricting or prohibiting proper flow and/or cleaning of the line.

Corrosion — the pipe has deteriorated and/or broken, causing collapses in the line and restricting flow.

Bellied pipe — a section of the pipe has sunk due to ground or soil conditions, creating a valley that collects paper and waste.

Leaking joints — the seals between pipes have broken, allowing water to escape into the area surrounding the pipe.

Root infiltration — tree or shrub roots have invaded the sewer line, preventing normal cleaning and/or have damaged the line.

Off-grade pipe — existing pipes are constructed of substandard material that may have deteriorated or corroded.
