Natural gas main - how deep?
Imagine my surprise yesterday when I started removing a concrete path that runs across the front of our house, and I discovered a bright yellow plastic pipe running *right* underneath the path.
I can only assume this is the natural gas main, as it runs in a direct line between the gas meter and the street, and there is nothing else it could be.
So the question is, how deep should this pipe be?
When I say it was running underneath the path, I mean I lifted a section of path, and there it was. No digging required. The concrete must have been laid right on the pipe.
I now have a problem. I plan on replacing the concrete path with a crushed gravel path. Obviously this pipe is now in my way. Is it the supply companies responsibility to lay this in a sensible manner, or is it mine?

there maybe a sticker in your meterbox, telling you who did the work.
Or ring your gas company.
Check with them before doing anything

My plumber told me the min depth is 500mm

At least 450mm cover ( includes thickness of concrete.)If you dont play it, it's not an instrument!

I'd say teh original builder / plumbers are responsilbe. Supply companies are only to the boundary
My last house was on a slope down from the road and it had a brick path 700 mm wide running across teh front, then a 1 mm high retaining wall. had the power cable under just under the brick path running across the front of the house, and a metre from where it was supposed to be. It may have been teh minimum 450-500 when it started.
THe water main was lying on the sand under the bricks.
At the end of the house there was a dirt mound higher than the path. When i was relaying the path I started to dig up this mound to the same level as the path. On the way down i passed a yellow pipe, grazing it with the crowbar, and continued down a further 300 mm to the path level.

gas supply from the meter to the house here is almost 100mm below ground level, nice gal pipe (errr, when it was new it was a nice gal pipe, it has a decent rust surface now), damn glad I found it before the back hoe levels the front yard tomorrow.
The house was built in the early 1960s', so I am guessing it was quite normal to have gas & water pipes only inches below ground level

Hmm, well mine was right underneath quite a thin slab. I reckon the slab was about 80-100mm thick. Thin enough that one swift smack with the sledgehammer turned it into a set of mini-slabs.
Guess i'll have to phone a gassie and get a quote for getting it deeper under terra-firma.

Hi sammy, i dont know about canberra but sydney that pipe (gold line) is installed by contractors employed by the gas company(AGL,Agility) in a similar fassion to your testra service cable.
My advice is call them up and tell them to send a contractor out and dig it down deeper (inside your boundry is 300mm deep outside your boundry is 450mm deep thats in Syd.)
But as with telstra they are a law unto them selves.
** If by chance you cut through that pipe it can be quite easily sealed off by folding the pipe over same as you would do with a garden hose and this will create a gas tight seal.

If It's the gas supply main Before the meter the Gas company have to do it. And they better do it for free.If you dont play it, it's not an instrument!
