Building over sewers

If you are building over or close to our sewer pipes, we will need to know so we can help to protect them.

Do I need your permission to build on my property?

Building close to or over a public sewer without getting our formal approval is illegal and it may also jeopardise the future sale of your property.

We're responsible for public sewers within our area and many public sewers which cross private land. We have to make sure that development is not carried out that could damage a public sewer, cause risk of flooding or restrict our access for maintenance.

Wherever possible we prefer to avoid the need to build over or close to a sewer by repositioning the proposed development or diverting the sewer. "Close to" is normally defined as being within three metres of the sewer.

However, there are some cases where the risk to the public sewer is small and where diversion is not possible, that we can allow building over or close to a sewer.

How can I get more advice?

If you're unsure whether your building works affect a public sewer you can find out by calling the relevant office number below.

If you have a query about something other than building over sewers, visit the help and contacts section for more information.
