I'm sorry for raising this so close to tea-time (or is it dinner?) well, it's tea time in our house.

I notice that these tanks are quite commonplace in northern Scotland, especially in more 'out of town' properties. Is the emptying of them a routine process, provided by plentiful specialists? Or is the removal of the contents a pain in the neck which causes problems/sleepless nights? Is it expensive?

I'd guess an average tank might need to be drained twice a year? with an family of four?? Are they buried deep below ground?

I have never encountered these devices but there seem to be so many it can hardly be a problem, or can it? I'm ignorant on this, would appreciate some guidance.

Another thing I know little about is Council tax in Scotland. Am I right in thinking that Council tax includes charges for water? I'm hoping so because otherwise the rates I've seen seem quite extortionate !

thanks

Alan
