Building over public sewers owned by Southern Water
If you want to build over a public sewer, you’ll need to check Southern Water’s requirements and get permission from them before you start the building work.
A public sewer will usually serve two or more properties. If you want to build over drainage that only serves one property, it is classed as private drainage. This does not form part of Southern Waters network, and you don’t have to get permission from them.
If you’re not sure what drainage needs involvement from Southern Water, contact them first or get advice from an architect or surveyor.
Shared property boundaries or party walls
If you are doing work on or near a wall, or building a new wall, that is shared with another property:
- check whether your work is affected by the Party Wall Act on GOV.UK
- search for a party wall surveyor
To ensure you are meeting your responsibilities, read fire safety law and guidance on GOV.UK.
