Gas lines and other utilities can be buried anywhere. It is important to take it seriously before doing construction and digging. If you are the one doing the burying, it is important to meet or exceed the legal depths for the safety of future generations.
What is the minimum depth to bury gas lines in Alberta?
How Deep are Gas Lines Buried in Alberta?
Gas lines in Alberta must be buried at least 24 inches under traffic areas such as driveways and parking areas, and at least 15 inches under non traffic areas.
This is distance from the top of the gas line to the top of the ground above. You should also account for the settling of backfill over time.
It is also required to run a tracer wire with the gas line. This is a metal wire that helps locating tools detect where the gas line is located.
A great visual chart that explains utility depths.
Never assume that just because these are the legal depths, the gas lines will actually be that far down.
The ground shifts over time, which can bring the lines up, or there could have been erosion from above.
There could also be questions about the integrity of the workers who buried the line. Someone could have been lazy or cut corners and buried the line too shallow.
Before digging anywhere you should call a locator service. They will look for gas lines and other utilities that you should avoid.
There are not for profit services that will locate these utilities for you at no cost. There may be a long wait, but it is worth the wait to do it safely.
