From the 2000 IRC. ( the one my jurisdiction uses) :

E3508.1.1 Metal underground water pipe.Ametal underground

water pipe in direct contact with the earth for10 feet

(3048 mm) or more and electrically continuous to the points

of connection of the grounding electrode conductor and the

bonding conductors shall be considered as a grounding electrode.

Continuity of the grounding path or the bonding connection

to interior piping shall not rely on water meters or

filtering devices and similar equipment. A metal underground

water pipe shall be supplemented by an additional

electrode of a type specified in this section or in Section

E3508.2. The supplemental electrode shall be bonded to the

grounding electrode conductor, the grounded service-entrance

conductor, the grounded service raceway or any

grounded service enclosure.

Where the supplemental electrode is a made electrode in

accordance with Section E3508.2, that portion of the bond-

ing jumper that is the sole connection to the supplemental

grounding electrode shall not be required to be larger than

No. 6 copper wire or No. 4 aluminum wire.

Let me clarify. You can connect it to your main cold water pipe within
five
feet of where it enters the building. You can also connect it to the fuse
box or anything that is grounding the fuse box


No you can't. Bad advice.
