Diverting Our Pipes

Large developersIf there are existing pipes in your development contact us as early as possible so we can work with you to ensure your project goes to plan.

One option would be to divert our assets to facilitate your development. Any diversion that we undertake will be done at the expense of the landowner/developer. However, we will always work with you to find the best, most cost effective, solution. Please be aware this can take up to 6 months from your initial enquiry.

Call us on 0345 026 8989 and we can discuss the application process and allocate your site to a dedicated engineer.

Locating our assets

You can use our Property Searches service, to check if there are any of our pipes on your development. These give an indication of the position and nature of the mains, but the accuracy of the information is not guaranteed and should not be relied on for development purposes. 

Before you start your development, the exact location of our pipes must be determined to prevent any damage. This may require trial hole excavations.

If we agree (in writing) for a developer to construct the sewer diversion, they must enter into a legal agreement and their contractor must complete a Request for permission to work on a public sewer form (PDF 377 KB opens in a new window). You and/or your contractor must not complete any work on the public sewer without prior agreement from us.
