Please help. Manhole close to rear extension wall
fas496
Posts: 2 Newbie
I am in the process of buying a house and plan to do a rear extension.
There is a manhole (shared sewer) which I believe will be very close the rear extension foundation; as close as half a meter. The drain from the manhole is connected to the sewer in the neighbour's property. Thames water owns the sewer and according to their
website, I will need their consent if the extension foundations are within 3 meter of the sewer. I have seen other forums saying that the foundations must be at least 0.6 meter away from the manhole?
Even if Thames Water allow me to move the manhole, I do not know if this will be feasible. I have these doubts (1) moving the manhole will involve moving the drains and the neighbour might object to this work entering their boundary. So this might be no-go then? (2) Anyone knows how expensive it could be to move the manhole altogether? A very expensive move will not justify extending or buying this property.
If I move the extension wall away from the manhole then the extension width might become so small that its unacceptable. I need to check the details for the plans.
Do I have other options? My aim is to make sure I understand my options fully before I complete.

Can't help on that 1 other than to contact the water authority and get it from the horses mouth. You don't need to own the property to ask what seems a general question. I'll give it a bounce for you anyway;);)I like the thanks button, but ,please, an I agree button.
Will the grammar and spelling police respect I do make grammatical errors, and have carp spelling, no need to remind me.;)
Always expect the unexpected:eek:and then you won't be dissapointed0 -
It will be very unlikely that you can move the manhole. You will need to bridge the sewer pipe - it must not take any weight. You will need full plans to give to Thames Water and they will ask for a lot of moneyDo you want your money back, and a bit more, search for 'money claim online' - They don't like it up 'em Captain Mainwaring0

He hasn't said that though, I think his issue is that he needs to buil;d up to it, not over it. Can you confirm OP?I like the thanks button, but ,please, an I agree button.

Yes, its the case of building upto it. Well almost next to it.
I have spoken to TW and they are not sure the drainage plan they have given me is accurate. Their plan shows no inbound drains and an outbound one going to the neighbour's sewer. This makes it private on paper right?
How else can i check what inbound and outbound connections the m/h has? By physically inspecting the manhole?0 -
Not feasible. The cost of professional work of this nature is too much.
Sorry best to find another house.0
