Building and Developing

Other developments
If your planned development requires a water main or sewer to be diverted, download our diversion application forms to keep your plans on track.

Diversions

If you have an existing Severn Trent water main or sewer on your site you may need to apply to for it to be diverted. In some circumstances we can give permission for you to build close to or over a public sewer.

Water

If you have identified a water main on your land which is owned and maintained by us and your development will affect it you will need to apply for it to be diverted. You will enter into a diversion agreement and Severn Trent will carry out the necessary work.

We don't give permission for any building to be built over a water main.

Sewerage

If you have identified a public sewer on your land which is owned and maintained by us and your new development will affect it you will need to apply for it to be diverted. Once you apply we will assess if we will need to carry out the diversion work or if you can enter into a self lay diversion agreement.

If you have a public sewer on your site and are making changes to an existing building that affect that sewer e.g. building an extension, we may in some cases give you permission to build over it. Find out more about this by visiting our build over sewers page.
