New copper plumbing

I'd like to install new copper plumbing from the street water meter to the house (and also inside the house). All existing pipes are galvanized. How deep do I need to dig to install the main water line and do I have to have it inspected? Also, should I even attempt to remove any existing pipe? And is there any additional information I should know?

First, contact your Building Inspection Department for local code, permit and inspections.
You will need a plumbing permit, an inspection before burying the line, and after the interior piping is completed.
You don't have to remove the old galvanized line in the ground, but you will need to remove it to get it out of the way for the interior re-plumbing.
Don't allow the old galvanized to come into contact with the new copper, except with di-electric connections, to prevent electrolysis corrosion.
They can tell you how deep (below local "frost-line"), etc. and other specs.
Good Luck!
