That is a local code issue. You need to check with your local code enforcement office, building inspector, or electrician. Higher is better, I would go with a minimum of 15' to keep delivery trucks and people carrying things from snagging on it. Of course, you shouldn't be running the main service yourself. That needs to be done by a qualified electrician. The building inspectors and power companies enforce this. If you don't have the paperwork that someone qualified did it, they won't turn your power on. As per answer one, that is a code issue which depends on which code your local authority having jurisdiction uses. To the best of my recollection, the NEC [National Electrical Code, a service of the NFPA (National Fire Protection Association)], specifies that aerial electrical conductors must be a minimum of 18 feet above a driveway.j3h.
trick question; electrical service lines may not run above driveways

The Canadian Electrical Code states in Rule 6-112; The lowest point in the dip from the point of consumer's connection to the utility connection point shall be no lower than 4 metres (13 feet).
The point of attachment of supply service conductors shall not exceed 9 m (30') above grade. The drop has be located so that the clearance of the conductors at any point above finished grade is not less than the following heights; across highways, streets, lanes, and alleys - 5.5 m (18'), across driveways to residential garages - 4 m (13'), across driveways to commercial and industrial premises - 5 m (16') and across ground normally accessible to pedestrians only - 3.5 m (12').
all the above
According to the National Electrical Code Handbook, clearance over public streets, alleys, roads, parking areas subject to truck traffic and driveways on other than residential property is 18 feet.
Salt typically lowers the freezing point of water, but your water line should be buried deep enough that it never freezes regardless of what happens on the surface above it.
It's not a matter of how deep electrical wire should be buried. The wire should be protected by plastic or metal conduit and marked suitably above ground - buried utility. I am certain that you will be burying a water line to the fountain "below the frost line" for your area, so consider placing you electrical wires at the same depth.

it should be 5 feet

A service mast is attached to the building, it stands normally above the building or at the highest point of the building, were no one can get to it. The service mast contains the wires from the meter base to the top of the service mast, this is were the power company attaches it wires so that the building has electricity.

immediately above the stop valve
ABOVE the sewer line and on an angle away
