Frequently asked questions
How do I connect a new property to the public sewer in Cornwall?
You will normally need a Section 106 application approved by South West Water. Once approved, we can excavate, make the connection and reinstate the ground.
Do you install private drainage as well as sewer connections?
Yes. We lay new drainage runs, chambers and manholes and connect them to the public sewer.
Can you work on sewers under the road?
Yes. Work in the public highway needs a permit or licence and traffic management, which we can plan as part of the job.
