Our sewers run under ground in streets, gardens, fields and land, so if you're building an extension you will need to check if there is a sewer nearby. We can then make sure that your home and our pipes are protected during and after the build.

You can find guidance on our page; building near public sewers.

You'll find our Buildover guidance notes which will help you before you start, including how to tell if there are sewers on your land and how to get consent to build if there is a sewer nearby.
