Building over a Sewer

Thanks Gothicfairy. You're right and I would never build over an inspection chamber and the plan is to get that moved, but as the build will be over more than 6m of underground sewer we have to get that diverted too (and still enter into a build over agreement as a small part of the sewer would still be built over). I think I am going to bite the bullet and get an Inspector round to have a look as I would always do things by the book and get the necessary permissions etc; this all might end up costing so much money in preparatory buildworks and fee's we may just not build the extension as large as originally thought and jsut do the side and not the rear, so wont be an issue.

Cyclonbri1, not sure what you mean but the sewer is owned by Anglian Water and the pipe goes all the way along the back of a row of semi-detached properties and I would imagine every house has an inspection chamber/drain cover and each houses waste water feeds into it. Sorry if I misunderstood what you were saying :eek:

No chap, :T, that's exactly what I was asking, you have a shared sewer as in my description, and that is totally different to a single private 1. I think;)

Yes - if the houses are pre 1937 ad they all share a foul water sewer then from the first house upstream in the run its a private sewer. At the point where the second house's output joins it (usually at an inspection chamber) it becomes a public sewer and the local Water/Sewage Utility has responsibility for it.

In the same configuration, if the houses are post 1937 then, shared or not, its a private sewer until it joins the main sewer in the street.

I called Anglian Water at the start to ascertain ownership and they confirmed it was owned by them. I am liaising with the local AW inspector who seems very helpful so I all I need to do now is decide on whether to do the full extension and get the sewer and inspection cover moved/diverted as well as getting a build over agreement for the small part that will be built on (but I think he said you couldnt do both, so its either build over or divert it!), or only do a part extension and leave them where they are (I'm leaning toward the latter, seems a lot easier and cheaper although the wife wont agree :eek:!)
