my god, your supreme ignorance is on display once more

If, by septic tank, you simply mean a bloody great tank full of ****
that does no treatment whatsoever, then of course you are right,
because it has no outflow and must be emptied - generally every monthh
or two - by a truck and a pump. Of course since there are no bugs to
kill you can sling what you like in it.

Not really a septic tank, more of a cess pit.

OTOH if you are talking about a private sewage treatment plant with
settlement tanks that use the actual bacteria to digest the **** into
acceptable fertiliser and purify the water that is then discharged on
a continuous basis, then of course they are ALWAYS FULL of water.

Right, you've just described a septic tank. Sometimes these apparently
have two chambers, but I'm not sure why.

Mine had THREE.

And it was still crap. The replacement Klargester that ensures aerobic
breakdown is infinitely superior.

The tanks are a crude way of getting better and better settlement of
inorganic sediments and such solids as may form.
