Running discussion with plumber,
2012 IPC, 603.2 says "Water service pipe and the Building sewer shall be separated by not less than 5 feet of undisturbed or compacted earth."
But 603.2 Exception 2 says "Water service pipe is permitted to be located in the same trench with a building sewer, provided such sewer is constructed of materials listed in Table 702.2."
Table 702.2 UNDERGROUND BUILDING DRAINAGE AND VENT PIPE gives reference to all materials allowed to be used within the building footprint or building drain system.
In my experience, we always separated the two outside the slab either by 5 foot or on a shelf in the same trench, 18" above the building sewer. Here is the deal... If a building drain meets code and you use the same material as in the slab outside the slab, then you should be able to run the water service in the same trench (his argument)... Opinions?
