Building and Developing

Diversions and disconnections

Need to move part of our network or be disconnected from our network


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.

Disconnections

If you require a disconnection at your property, here’s some information for you to find out more.

 

What is a permanent disconnection?

Your site may require a permanent disconnection. This is free - all we have to do is disconnect on the public boundary. So if you ever need the supply again, you’ll need to pay to replace the pipework, plus our normal new connection charges.

 

Things to bear in mind

If your water supply also serves another customer’s property, then we might have to separate the existing supply first, and you would need to pay for this. In these cases, we normally do a site survey to estimate the amount of work and the costs. You can apply online to separate a shared supply if this is what's needed.

If you have any questions about disconnections you can email us at customercare@severntrent.co.uk or call us on 03457 500 500

If the property is still occupied, we can’t disconnect the water supply. If this is the case, please let us know when the property will be empty.

The registered owner needs to give us authorisation for a permanent disconnection. If the person who fills out the form isn’t the registered owner, but you want a permanent disconnection, please include written authorisation from the owner.

After we’ve disconnected your water supply, surface water drainage charges for commercial properties might still need to be paid. This is because although the property is empty and no water will be used, it will still benefit from surface water drainage (removal of rainwater), which we provide. This has been approved by Ofwat.
