Why would you *want* a septic tank in your garden?

Considering it's out of the way and you have right of way for maintenance
etc, why change anything? - it must have been like this for many, many years
before.

I was wondering, even if there is a formal right of way which has been
proven and verified by a solicitor, is it still possible that the owner
of the land on which the septic tank is situated could in the future
legally require the owner of the septic tank to remove the septic tank
from his land?

What I mean is, even if there is a legal right of way to the septic
tank whilst it is located in the other persons field, could they
legally require it to be removed and therefore leaving the cottage
without a septic tank?
