Can I build over a water main?

No, you are not permitted to build within 3 metres of a public water main as we must have unrestricted access to repair, maintain or renew our main when required. There are further details of an alternative process (water main diversion) within our Guidance notes.

Why do I need permission to build over or close to a public sewer?

We need to approve your proposal of works (even if you have already had planning permission granted) as your building could cause damage or prevent access to the sewer. Some conservatories and minor works don’t always need planning and/or building regulation approval, but if you plan to build over or close to a public sewer please contact us for advice. You'll find more information here.

What if my extension was built over a private sewer before 1 October 2011?

If the property was built before the transfer of private sewers to us on 1 October 2011, the works are legal as there would have been no need for approval before this date. There's more information here on building over a public sewer after this date.
