Rainwater is a no, no. The volumes of even a small shower on a decent
sized roof will flush a septic tank through far to quickly...

What is the ill effect of that?

I am no expert but the bacteria has to have some time to digest the
sewerage componant before the discharging water will be safe to soak away
into the surrounding land. It is not normally to put rain water through a
septic tank, this normally goes to seperate soak aways, often several one
for each down pipe.

I'd have thought that there will be similar bacteria in the ground to deal
with the anaerobic treatment of sewerage components. We often used to make a
'long drop' when camping, it caused no problems.

They can and do, but regulations deem the outflow should be safe.

I'm sure that's right but it really does amuse me about The Authorities'
ideas of 'safe'. You'd think that the Earth was sterile, that all animals
from the smallest to the largest didn't deposit their excretions everywhere
:-)

And when it comes to burying animals and people in other than 'authorised'
places ... well ... !
