Did you know that three-quarters of the breaks to underground pipes are caused by an error or negligence of the people doing the excavating? Around your house, there may be essential underground systems that you and your neighbours rely on, including gas lines, power lines and television cables.

    1. Submit a locate request to Info-Excavation online or by calling 1-800-663-9228. It’s simple and free!
    2. Have your localization plan on hand before you start your work. Read it carefully, as there may be additional instructions before you begin.
    3. Find or mark the location of the pipe on the ground, according to your localization plan. Keep this marking in place for the entire duration of your work.
    4. Dig by hand in the buffer zone (i.e., 1 metre on either side of the pipe).
    You’ve hired contractors to do the work? Ask them to perform the necessary verifications or forward them the locate report you received. Every broken pipe requires the fire department and Énergir’s emergency service to intervene. See our document to interpret localization plans and steps to be respected when working near natural gas networks.

    3. Locate Énergir’s marking or mark the location of the pipe on the ground, according to your localization plan. Keep this marking in place for the entire duration of your work.
    4. Use a soft excavation method (shovel, hydro excavation, vacuum excavation) in the buffer zone (i.e., 1 metre on either side of the pipe).

    You can use our prevention sheet, developed jointly with the CNESST, to ensure that you have implemented all the best practices when working near the gas network.

    Coordination of work

    If you are intending to perform road work, please notify Énergir during the planning phase so the company can make improvements to its gas network at the same time. Better coordination of work activities will benefit all citizens.

    See our document to interpret localization plans and steps to be respected when working near natural gas networks.

Depth of the natural gas lines

Natural gas lines are not always buried at the same depth. While the pipes themselves do not move, the contours of the land where they are located may alter over the years. Check first by digging manually or with vacuum excavation equipment so as to avoid damaging any underground structures.

 For more information and to know what factors you need to take into account when planning and carrying out your work, refer to the following guide.

It outlines the steps to follow and provides information on the technical requirements for protecting natural gas installations, thus ensuring public and worker safety.
