A blocked sewer may be the result of a utility line, which was accidentally “cross bored” through a sewer line.

Call before you clear sewer lines.

If unable to visually verify that a “cross bore” blockage does not exist, Call Dig Safe 811 before attempting to clear a blockage beyond the outside wall of a building.

Call Dig Safe at 811 and request an emergency utility mark out. If utility markings cross the known path of the sewer line, it may be a cross bore blockage.

If you suspect a cross bore blockage.

DO NOT attempt to clear the blockage with a mechanical device or high-pressure water jet. Get help from the involved utility operator. Vermont Gas can be reached at 800-639-8081.

If you suspect a natural gas leak.

  1. Leave and instruct others to leave the area.
  2. Call 911 and then Vermont Gas at 800-639-8081.
  3. Do not operate any equipment & eliminate sources of ignition.
