Does anyone know the depth a secondary gas line to a garage needs to be in Calgary? I hear 12" is standard and I hear 18" as we'll. I know going to the house (primary) needs to be 24"
Gas line trench depth to a garage

40 inchs is the average, deeper is better, anything less is dangerous. whoever told you 12 inchs is a friggin idiot period. if you want the recommended depth call the gas company, 24 inchs is still to shallow, where are you getting your numbers from ? the taliban!!! be safe, anything less than 40 inchs is dangerous.

don't worry about minimum code, put it deeper period, safety is more important, heard of guys putting in fence< contacting electrical cables and gaslines, don't be one of those. but you can do what you want on your own property, and i have just about seen it all. guy cut his phone line putting in a pup tent stake. totally up to u listen to whoever you like, but industry is around 40 inches.

don't think they have a clue as to depths, just an answering service as far as i'm concerned.

You call. They send someone from Telus/Atco/gas coop/etc to mark their buried facilities. No charges to the caller/ground disturber. 1 800 242 3447 if my memory serves me.
If I lived in the city and built a garage that needed a gas line, I would not think I would bother to dig a bunch deeper than required by code. Low pressure gas lines and cables are called shallow utilities. One reason for this is IF there is a failure/contact with the line it can be dug up easier and safer by NOT going deeper. I didn't make this **** up! Lol

I don't have the code book handy and don't feel like googling and posting it here. I just remember him saying that was code. We need Magnet to chime in here with his experience. I've seen tons of small diameter yellow plastic gas lines in hydrovac holes very shallow.
The 6" live steel pipeline I drilled under and pulled back my clients 6" steel pipeline this morning north of Edson was barely 3'6", and meets code I do believe as well at 1.1m. I crossed under it with 5' separation, so I get your point Imdoo'n, more is better, but IMO not in the case of a 3/4" gas line building to building in a city lot. My thumbs hurt!

40".... Are you crazy! You do realized a gas service after the regulatory is approx. 0.5psi, lol were not dealing with big diameter high pressure gas lines.
anywho hopefully someone that knows for sure chimes in, I think the code is csa z662, which states 300 below grade. But I just don't know for sure.

Depth depends on sticktuitiveness, number of beers drank and number of shovels shovelling. Wait on material also plays into effect. Happy diggin.

Maybe you should be ranting about safety to those guys who are digging posts where there are utilities present.
You should be doing this anyway if you are planning on doing any digging in your yard.

There are some who don't know, thats why I wrote the number. I do ground disturbance on a daily basis.

hmm, seems like i get to mark it before you even show up. for what it is worth, first call will inform all members on there service that the caller requires utilities to be marked. as it stands now they will mark there lines to the meter on the power pole or on the house etc. secondary services from the house to garage or out buildings they will not do. and gas co-ops ad gas companies are not all marking lines past the meter, some do though. anyway put the line deeper, people forget where they are.
but you can do anything you like, as once it is buried "out of sight, out of mind".
My brother-inlaw did his a few years ago. 18" minimum and had to leave the trench open for the inspector. Some municipalities/cities will let you get away with showing the inspector pictures of the trench with a ruler or tape measure to display the depth if you're really concerned about leaving it open for too long (safety reasons for kids and stuff). As far as forgetting where you buried lines, I made a map of my property for future reference.
