Probably not.  But perhaps somewhat...

One of my early antennas used the water faucet under my
bedroom window as a ground, and it worked.  Sort of...
But that was back in the days when all of the water pipes
were likely to be galvanized steel.  Today most of them
will be plastic (PVC or CPVC) and that doesn't make a
very good conductor.  Or they might be sweated copper,
which could be a good ground.

But grounds are confusing - there are several different
reasons why you might want to use a ground, and what works
for one application won't do for another.  Looking at
the water faucet ground that I used way back then, it
would stack up like this:

1) lightning ground - probably a bad idea.
2) AC safety ground - might work, might not, but the
third wire of a grounded outlet is better.
3) antenna ground for vertical.  Poor, but I made contacts.
4) DC ground for draining stray static charges - good.
5) RF ground for station - usable on 40m and below,
poor on the higher bands due to wire length. But you
rarely need one of these anyway.

Today I know that none of the faucets in my house are
connected to metal pipes, so they would be useless for
any of these purposes.

I have a spigot running from my house for my garden hose in my back yard very close to the room of my house where my shack will be located. I am thinking of running my ground wire to this spigot,instead of burying a ground rod, since I assume that the spigot is a cold water pipe. Am a correct that the spigot will make a good grounding source?
