i dont know whho cares Most concrete foundations are buried 4' to get below the frost line which is around 3'.
The top of the footing must be below the frost line. This varies from one geographical area to another. To be sure, contact the local building permit office where the building is to be located.
If you live in an area where you have frost it should be below the record frost depth, usually in the North it is a minimum of four feet. If you are running copper in the ground out west you can go substantially higher in the ground due to the lack of frost. I would recommend that you look at the building codes for your particular area as the requirements for each state and region can differ. Bed the pipe with sand below and above, 4-6 inches is a usually required above and below depending on ground conditions and relevant region of the country. You also want to make sure you are using the right grade of copper pipe made for direct burial.
It can be really deep, I would help you out but my pockets are not that deep
The depth and width of a footer for a concrete pad will depend on various factors such as the load that will be placed on the pad, soil conditions, and local building codes. Generally, footers are often at least 12 inches deep and extend beyond the pad on each side by at least 6 inches. It is recommended to consult a structural engineer or local building authority for specific requirements for your project.
Up to July 2008 it was 4' per the NYC Code. I haven't dealt enough with the newly adopted code. I imagine it hasn't changed.
no Frost
The frost line in Springfield, MO is typically around 30 inches. This is the depth at which the ground is expected to freeze during the winter months. It's important for construction and landscaping to prevent frost heaving.
Average is 4ft, building code requires water pipes to be at least 6ft deep to be well below frost line and safe from frezzing.
no Frost
I found this link...I hope it helps. From what I can discern the frost line is at 42" http://www.ci.omaha.ne.us/planning/building_development/Code%20Info%20Sheet%203-06.pdf

According to the City of Toronto (http://www.toronto.ca/water/supply/system/watermains.htm): "Watermain pipes are buried in public streets, about 1.5 m deep, just below the area where frost ends or "the frost line"." 1.5 m is about 5 feet. -289- 42" by code - Ontario Building Code.
The frost depth refers to how deeply frost can penetrate into the ground. In Martinsville, Virginia, the frost depth is around 18 inches deep.
