Anyone any experience of a domestic pumped sewage systems where the
"effluent" is pumped from a lower holding tank up to the main sewer in
the road? A bit like an enormous macerator I suppose.
I'm contemplating buying a house with such a beast (make / model / age
unknown as yet).

Best to be avoided where possible, but if the dwellings sewer is lower
than the main sewer then either you do it this way or have someone
come and manually empty it from time to time.
There's a few properties round here that have them and I've not heard
of any major problems with any of them, apart from minor blockages
caused by lack of service\broken pipes\dodgy installation. Some of
these are a few years old, some are 20 odd years old.
Budget for a service if it's not got a history of regular ones, loads
easier to work on now rather than when it's backed up, dark and
No personal experience but I know a cottage up
the top that has one. It is relatively trouble
free but if something does break down, (or a
power cut lasting a few days), then it is panic
stations in case the holding tank overflows.
We used to be on a septic tank and (imo) if you
have any sort of private sewerage system then you
are almost certain to end up diy'ing the regular
maintainance and various repairs. No great problem
but, (like exhausts on cars), they always seem to
need working on in the depths of winter.

There seems to be a persistent rumour that it doesn't work out too well,
though I've never found out why. I guess one problem is that if it goes
wrong, then you end up paying for the repairs.
I guess it is a good negotiating point, but I don't think it would put me
off (subject to trying to establish "condition", as others have said).
Remember that they are very widely used by the water industry so it is a
mature technology. The pumps are also designed to be as easy to change and
service as possible. I guess it it were mine I would wonder about having a
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 shite and just dangling there on a length of
A Saniflo on steroids......
During a recent trip to France I looked in several bricolage sheds.
Not one had a Saniflo.
I am convinced that this is a secret weapon of Napoleon against
the British - revenge for Waterloo (IYSWIM).
Does your vendor look anything like the man in this photo?
I saw one yesterday.

I wonder who thought it was a good idea to install a saniflow in such
a location (with the obligatory waste going uppards pipe).
Obviously decent sewage pumps work..the main problem with a saniflo s
not the pump, but the macerator. It isn't powerful enough for everything
you can throw at it.
If you have the land space and suitable water tables installing your own
sewage unit - like a biodigester - is possible as well. I have one and I
get a water rebate, and it only needs emptying every few years and cost
about 6 grand to put in..happy to simply dump its outflow into a
ditch..no smells at all.
