Drains below road? Sewage pumping?

[r896neo]

Hi i am interested in buying a house with an unusual problem.

The house in down in a bit of a sump and the road which is about 40ft from the house is higher by a good 6 feet. Upon giving the house a once over i noticed that there was an unusual concrete plinth that ran along side the house and across the drive and then up the boundary with the neigbours heading towards the road.

After not finding any gulleys under downpipes and no manholes anywhere
I soon realised that bizarrly enough this was the main drain running about 2 feet above ground and encased in concrete. The problem however is that the house is a bad layout and would need extended however doing so would mean moving this drain as it is above the internal floor level. Also where it runs across the driveway it would stop any chance of building a garage.

The best method as i have so far come up with would probably be to leave the existing drain from the road to about 5 feet into the garden to and build/ bury a tank and pump? Then relay the house drains to a sensible level and come into the base of this new chamber/tank. The head to reach the old invert level would be approximately 8ft. I was hoping someone might have done this or installed something similar for somebody else before and have some idea of the cost?

Alternative ideas welcome. Cheers

For what it`s worth - I maintained a pump station @ a large Country House hotel - It was a pain in the arse . After I left there , I found that the new owners had renewed the half mile of sewer that ran across the park and managed to get a suitable fall due to the lie of the land . And for the pedants here it was a LOT less than 1:40 fall . There are lots of small self contained sewage pumping/lifting sets in Glassfibre containers , have a google But I wouldn`t bother myself - let alone buy a house that had one fitted.

If the entire house and surrounding area isn't flooding then drainage of some kind must be acheiving its purpose.
If it was built in a true sump hole then it would flood in wet weather and be a permanent lake.
So fit your own waste water treatment plant and follow the flow direction to the lowest level away from the property.

yea have had a google but was looking for any first hand costs or opinions if possible.

I am inclined to agree with this but it is owned by a bank and has been vandalised a bit, so they desperately want to shift it before someone burns it down so it may be too good a deal to refuse.

don`t believe a bank can get desperate - they`re just using smoke and mirrors on you - like they did to the country I personally would pretend I was interested, then @ them as the place rotted to nothing - All robbing b`stards
