Hmm, something needs to explain the presence and location of your water main, which is now at risk, it should be at a depth of 2'-6"/750mm to protect it from frost, but in these circumstances that should be considered horizontally as well as vertically. Does your neighbours water main run in the same way, what of the other two properties, are they laid out similarly?
It could be that your water main burst at some point in the past and the path of least resistance was chosen to relay the new one.
I have often wondered if, when the properties were originally built many many years ago, they had steps leading up to the front, and maybe that is why utility pipe are buried in such a way. I have a gas line on the other side of the drive under a hedge. Sorry, I can't really answer your question as, as I have mentioned previously, I have only been here 15 years.
