Building over drains

Anonymous user 23/02/2024 - 3.19 PM

Hi, We're looking at building an extension out the back of the property which is where our foul waste drains are. Our neighbours drains feed into ours which then leads to the public sewer in our garden which we have a manhole for. Anglian water have said because the neighbours feeds into ours it's a public sewer. The issue we have is that the public drain is about 14ft deep and our pipes feed in at this level so we know somewhere under where we want to build. So in regards to the foundations will we have to dig as deep as the sewer or are there other ways round it that are more cost effective than half the cost of the extention being on the foundations.

Are you a tradesperson and able to answer this question?

Hi in response to you question,you shouldn’t have dig your footings to that depth, it’s normally about 900mm possibly deeper if there’s clay? Your more than likely gonna have to have a separate inspection pit built, however regardless of that you can pop into your local planning office and they’re obliged to advise you, they’re there to help you. I hope this helps. Best regards George Scott

Pesonaly I would check how close you are allowed to build to public sewer, I’m in the south and we had potential extension stopped at planning stage by southern water, as they said we were not allowed to build as close to sewer as customer wanted. Can’t remember measurements but probably different in each case.

Hi When you have plans drawn up your designer should obtain utility plans for the property (if available) to ascertain where the pipes are. I would then advise that before you submit anything to planning, you send the drawings across to your utility provider and make sure they are happy with them. If they are, then you will have to agree to a build over agreement and you can then proceed with planning. Hope this helps Paul
