No, its not true.
You need to take precautions in the foundation design to protect the drain.
In the majority of cases this will be possible.
If it is not possible, or impractical or costly to do, then you look at
other options which involve diverting or altering the drainage system.
Thanks for the replies,
We contacted the water board to get a map of the drains, and the guy
informed us that we can't build over this pumped foul drain. We got the map
today and can see that this pipe runs underneath an extension that was built
a couple of years ago by the prevoius owners. The extension needed planning
permission + building regs etc., which we have - so I was wondering if we
needed to do anything, why it's not on his map and why you can't build over
The other gotcha as a friend of mine found when building within a
small distance of a main sewer is that the water company can charge
you a fee for doing so. The basis is that it makes it more expensive
to make changes/repairs to the sewer later so they make a charge to
cover future extra costs.
My understanding is that it is possible to do so, build over the
sewer. Maybe best to speak to building control at the council again
providing this information. They will certainly be making other
requirements when they inspect the footings.

This pipe is inlikely to for part of the public sewer if it is still on
private land, and as such should not attract any influence from the water
company - unless they want to foot the bill to pay for any particular
alterations they may want. The water companies drum it in to us that any
leaks from drains or supply on our property is our responsiblity.
The control of sewage pipes and records, was removed from LA control a few
years ago, and passed to the water companies so local councils are no longer
concerned with issues that they are not specifically responsible for.
On the face of it, I would say that your friend was conned by the water
company - how can they charge for something that "may" occur in the future?
In five years time, there could be some technological break through that
make repairs cheaper - will he get a refund? How do you predict costs of
which you know neither the material or labour or even the scope of the work?
He should not have paid anything.
He would have to provide the reason (regulation) why you can't.
There may be a easement on your property deeds in their favour, but this is
There is no technical reason why you can't, and this would not conflict with
any planning or building regs.
If the extension is already there, what is the problem?
Also, plans can be wrong or out of date, and a lot of the time you find that
services are not where they are shown on the plan
I'm just curious to find out why he says "can't" and yet it's been done.
The pipe would have been laid about 10 years ago - the extension built 2
There is always the doubt that the extension will have to be dug up if pipe
maintenance is needed.
From what I've read on the North Cornwall website and whats been said here
I'm happy that its all OK. Its just a shame that its not a standard foul
pipe as we could then get rid of the <whisper> saniflo </whisper>.....
Hence why we requested a drainage map.
