Now that most of us are cognizant of our environmental impact and
responsibilities, shouldn't you install a holding tank anyway?

Why?

If I understand correctly, US regs allow the dumping of raw sewage 3
miles out to sea. If this is true what is the environmental impact of
my not having a holding tank?

And if I did install one what do you think I should do with the tank
after it is full?

Take it 3 miles out and dump it.

I suggest that you are unfamiliar with the conditions in this area.

My anchorage is located in a channel between Phuket Island and the
Mainland. the tides run at approximately 3 knots during the height of
the flow. The entire channel is swept (normally) twice daily, into the
Indian Ocean to the West and Phang Nga Bay toward the East. On both
the coast of Phuket and Phang Nga are villages, all of which have
runoff from shrimp farms, sewage systems, fertilizer and miscellaneous
fish processing plants, etc., it seems far fetched to suggest that I
and my wife are adding significantly to any existing contamination.

Further, I might add that the marina has a much higher fish
concentration that other parts of the channel - makes you wonder what
fish eat?

We have salmon farms here. Enviros will tell you the ecosystems under
the farms are destroyed due to the concentrated fish doo.
Actually, the ecosystem is more lush under the pens and the crab
fishermen set their pots near the pens because it's better crabbing.
A related situation happened when the state tested a nearby bay for
ecoli. The results were very high and the enviros immediately started
calling for removal of the septic tank systems along the shore.
Further testing determined the source of the problem was from feces
from the hundreds of seals and sea lions using the bay.
