what does your architect/designer say?

their searches usually show whether the drain is privately owned or not.

on his drawings the only drain he got on a search was the foul drain which apparently goes thru the extension towards the middle and goes out into the garden north bound

drain alterations can be straight forward, as long as their geography deems them so.

deep drains usually means having deep pockets.

as long as you privately own the drains and they are reasonably accessible, then costs should be reasonable.

if the builder is a gorilla and attacks the drains with a digger, breaking all manner of services then - £££££££££.

you will need to apply for permission to the owners (usually the local water authority). this comes at a preset price, which you will have to pay.

^woody^ will tell you more when he is online.

LOL - you make it sound like this manhole has suddenly appeared from nowhere and plonked itself right where the wall needs to go

Obviously, the plan drawer must have left his labrador at home that day, and in any case he is taking the easy way out and advising you to "see what the BCO says".

You have paid the guy to design the extension, so that includes designing over drains or designing moving them. I would give him a kick up the r's

If this is a public sewer then you will need the water authority's permission. When the council check the plans they should inform you if it is a public sewer.

There was a similar post very recently on this - have a search its not too far down the page.

If it is a public sewer then the authority may let you move it under their supervision, or may only let their approved contractors do it. Or may not allow anything.

If it's a private drain, then if you have to move it then its just a case of sorting out the best place for it - or if it can be removed all together. It's site specific.

As it is on the neighbours side, then you may have to agree access. But theoretically, you could probably just move it and fill the existing one in without disturbing the surface.

If you have notified under the Party Wall Act (if it applies) then the drain work should be covered in the award.

thanks woody ,,il get on to the guy it was covered with soil at the time ,but i think if he don his searches properly with the council he should of found it

thanks

OK, if it was covered, then it is not his fault.

Sewer maps are notoriously unreliable and so it may not be on them. He did well if he actually did a search! Many don't.
