Just out of interest - what criteria does one use to judge when a
spetic tank does require pumping out?

When the sludge is deep and so there is not much space for liquid.
Infrequently.

The interpretation of the above
thread is that a cess pool requires regular pumping - yearly?

Depends on the size and amount of liquid put into it. There is no
one answer.
