I was digging a manhole in my drive and cut through a yellow plastic gas main 12" from the surface. There was no marking tape. Furthermore it is the supply to the property next door and has obviously been teed off my main.
This raises the following questions:-
1) Should it be on my property anyway. I thought all service supplies should be brought into each property independently.
2) Should it have been deeper (450mm).
3) Should there have been a marker tape above it to indicate its presence.
Any information regarding this would be much appreciated.
