Does anyone know if someone has a septic tank, are there any ongoing
maintenance issues associated with them?

Or is it usually just a matter of having it cleaned out every so often
by a specialist company?

If so, on average how often would a septic tank be emptied; and how
much does this cost?

Any info is much appreciated...Thanks!!

You'll probably hear lots of differing views but the key effect on cost of
running a septic tank is how well you treat it. If you bung all sorts of
liquids and solids down it it won't function well and will need regular
emptying. But if you just put proper bio-degradeable stuff in this stuff
will degrade most effectively and there'll never be any cost.
