    Default Grounding after changing to plastic service line

    My #4AWG main grounding wire terminates with a clamp on my galvanized service pipe just before it leaves the house and goes out to the well, which is about 15 feet outside the house. The house plumbing is all copper. If I replace the galvanized service line with polyethylene, could I extend the #4 ground wire outside and clamp it to the steel well casing, and forgo driving two ground rods into very rocky soil? If this is allowable, is there a specific clamp designed for such a purpose?
