Diversion of water mains
If your development site currently has a public water main within it, a diversion may be required to allow your development to progress.
Anyone with an interest in any land which contains a water main or associated apparatus has the right to request the alteration or removal, including diversion (generally referred to throughout this document as diversion) of that apparatus to accommodate proposed improvement of that land. This right is granted by Section 185 of the WIA91, and extends to anyone with an interest in adjacent land where the presence of water mains or apparatus would hinder proposed improvement. This does not apply to water mains in any public highway.
It should be noted that we do not allow building over any water mains or associated apparatus. Please click here for more information.
Application form and guidance notes
You will also need to complete the Risk Assessment for Water Pipes in Land Potentially Affected by Contamination form.
Please complete all sections and provide the information requested so that your application can be processed as quickly and accurately as possible.
