Moving a Public Sewer on my property

Yes, moving a public sewer on your property typically requires approval from the local authority. Public sewers are part of the overall sewerage infrastructure and are usually owned and maintained by the local authority. Before undertaking any work that involves moving a public sewer, you should contact your local authority to discuss the proposed changes and obtain the necessary permissions and guidance. They will have specific regulations and procedures in place for such situations, and they will be able to advise you on the requirements and any potential costs or restrictions involved.

It has to be approved by the building inspector

It would depend on the size of the sewer and whether or not there is a manhole on your property for rodding/clearing it. Your architect or site agent should have been in touch with the local water board to apply for a ‘build over agreement’ which is a permit to build over it or around it in line with the Building Control. I hope this helps.

If it is public needs to be approved

If it’s a shared sewer you will need to speak to Severn Trent , just had a similar issue on my job the building inspector will tell you to speak to Severn Trent , you’ll need a drain survey before and after any drainage work is done
