I have a pipe of some kind buried about 6" below grade in my backyard. Photos are provided below. I have no idea what this line might be, and was hoping to solicit ideas. Whatever it is, it appears to be abandoned / unused, judging from the poor condition of the line. I have the local "Dig Safe" utility authorities coming next week to map out known services, but would like to know in case they do not have record of this.
It looks like the line would run between my house and my garage. But I have no plumbing in the garage (6" seems to shallow for water anyways). I have electricity but that cable is aerial, along with phone and cable lines from the back alley to the main house. The gas main is under the road at the front of my house, and so my gas meter / line are obviously there too. Similarly, the water main and water line are at the front of my house.
The garage was rebuilt about 5 years ago (before I owned the place), so I don't know if this pipe might have been used with the old garage and since abandoned.
I live in Toronto, Canada, if that factors in.
