We felt quite pleased with ourselves finding it as various owners since
1915 had looked, but no one had been able to find it. not surprising
really I had to go down 15' before I got there! It was dating the rubbish
and infill on the top of it that gave us the approx date it was last
looked at.
Most people I know with modern ones have a yearly contract.

I think there might be quite a lot in that last sentence, Charlie. I'm a
bit concerned that the OP is hearing about people who haven't touched a tank
in 15 years if his house's previous owners are on a yearly contract! I
wonder if a specialist surveyor exists for such things?
