What depth is water supply pipe usually at in a townhouse?

What depth would you expect a water supply pipe to be at, at a typical new suburban all-the-same townhouse in a moo baan? The water supply pipe from meter just outside my drive to the water tank plumbing at the back of the townhouse..

Really doesn't need to be deep, and probably at the depth of the driveway 10+cm, whether running under or along side of it, and hopefully not 'in' it.

 

As long as you got a ballpark idea where it is, no worries.  If cutting across a grassy area, I wouldn't expect to be much deeper than 30cm.
