Building and Developing

I have a public sewer on the site of my development, what do I need to do?

If you have a Hafren Dyfrdwy owned water main or a public sewer running across your land where you are proposing your new development you may need to divert it. You can obtain a copy of our records by requesting our records

Following the private drains and sewers act and the change in ownership of these sewers they may not yet be updated on our records. You can check if a sewer has been transferred by filling in our application. 

Building close to or over a public sewer without getting our formal approval is illegal and it may also jeopardise the future sale of your property. We prefer to avoid the need to build over or close to a sewer by repositioning the proposed development or diverting the sewer.
