Extension Drains Advice

[Sawkijon]

Hi all,
We have just started a new 2 storey rear extension and on day 1 hour 2 we hit a problem.... The builders uncovered a private sewer drain none of us knew existed. It turns out all our soil pipes feed into it and it runs exactly where our foundations are supposed to go......

The options were looking at are

• move the drain completely to run down the side of the house directly to the sewer in the road.
• Move the back wall of the extension out another meter and build a air tight manhole cover for it.

Our preference would be for the second option, but the builders are on site and the planning permission is for a smaller extension so we could incur another 8 weeks of planning approvals....

Has anyone come across this issue before and what did you do? I'm panicking a bit as we can't afford a massive hole in the budget this early on .

Thanks

move the drains. not a massive job if you've got a digger on site.

Wouldn't option 2 (ignoring the planning) also need a build over agreement?
My neighbour build an extension without one and had a nightmare getting one / had to undo a lot of work.
Although not building as per planning sounds like a bad idea

Could you go for option 2 and go for retrospective planning?

100% option 1, it's work for a digger to do which you have on site now.

Building over drains/sewers creates it's own problem and there's no gurantee option 2 would be approved either.
