Anyone any experience of a domestic pumped sewage systems where the

I'm contemplating buying a house with such a beast (make / model / age
unknown as yet).

You need to find out if it takes anyone else's turds away as well as your
own - I recently worked on a house, one of a small group of houses (about 6
or 7) and this bloke had the main tank and pump in his back garden - it had
it's own electricity supply and meter in a box (complete with orange
flashing light!) beside his lawn.
The electricity and service charges were split equally between all the
residents and it's written into the deeds or some other legal document that
they all have shared responsibility...he's lived there 7 years and it's
needed servicing twice, odours - none, although it whiffed a bit when I had
to remove the cast iron lid so I could raise it up by 2 courses of brick so
that it was level with his lawn...the pump was a fairly gigantic thing,
about 4ft long, covered in ****e and just dangling there on a length of
chain
