Its a pity really that we did not make clear at the beginning of this
thread that these tanks need de sludging not emptying, and the amount of
build up depends on how much usage as well as the design of the tank and
lay of the land.

Yes ... thoughtfully

A large tank of old fashioned design will seldom need attention and will
tolerate abuse, where a modern tank will need de sludging more often and
will work a lot better if some attention is payed to what goes in it.
Here I do speak from some experiance, having had to cope with ship board
systems that were physically very small for the numbers of people they
had to cope with.

I'm wondering whether it might be an idea to build one ... We'd like a
compost toilet but can't find instructions anywhere, CAT wasn't helpful.
