Pipeline Replacement Process

1. Surveying the right-of-way

2. Clearing the right-of-way

3. Transporting the pipe to the right-of-way

4. Welding the pipe

5. Digging a trench for the pipe

6. Lowering the pipe into the trench

7. Backfilling the trench

8. Pressure-testing the pipe

9. Restoring the right-of-way to its preconstruction condition

Five Steps Forward

1. Preconstruction

Crews will mark the gas lines and the other underground lines to help prevent accidental damage or disruption to these services during the pipeline replacement work. It is important that these markings and flags remain visible throughout the project for the safety of the public and the crews at the job sites. The paint used to mark the lines is not permanent and will wash away gradually.

2. Main Replacement

Crews will replace the gas mains that often run along the street or behind the curb. This project will involve “open cut” pipe installation, where we will dig a narrow trench to install the pipe. Customers will receive a doorhanger one week prior to replacement work in their area.

3. Service Line Replacement

Once the new gas main is installed, individual service lines to homes and businesses may need to be connected to the new gas main or replaced altogether. The actual work to connect the existing service or replace it entirely could happen several weeks after the initial gas main replacement. Customers will receive a doorhanger two days prior to the service line work on their property.

4. Relight

Connecting and/or replacing individual service lines will cause a brief disruption in your gas service. Once the service line is connected to the new main, an Atlanta Gas Light contractor or field service representative will schedule a time to enter the residence or business to relight all working natural gas appliances. This step is coordinated with the occupant, resident, or property owner so that someone can be on-site. Customers should NOT attempt to relight their appliances.

5. Restoration

Cleanup and temporary restoration will occur as the project progresses. Final restoration will be conducted at the end of each phase. It is Atlanta Gas Light’s goal that any area disturbed by the pipeline replacement work will be restored as closely as possible to its preconstruction condition once the project is complete, while adhering to all local ordinances.

For the safety of the community and our crews, this project will require extensive lane closures. Traffic control measures will be put in place. Atlanta Gas Light will work with property owners and managers to ensure that parking lotsare accessible during construction or that alternate parking is available. You can also expect noise from machinery and sidewalk closures. We are notifying local public safety officers of our construction plans.
