Pipes that only collect wastewater from your property, and which lie inside your home or within the boundary of your property will remain your responsibility.
If you have a problem with any of these pipes we recommend that you contact a reputable drainage contractor, who will be able to help you. The costs of fixing any faults on this pipework will fall to you or your home insurers.
Pipes that drain your own home, but lie outside your boundary and pipes serving both you and your neighbours are likely to be the responsibility of Welsh Water.
If you are unsure who is responsible for the Wastewater pipe, please contact us on 0800 085 3968.
To continually improve the accuracy of our drainage records we’d welcome copies of any plans you have which show the drainage around your home.
Please email a digital copy (preferably scanned or photographed in .pdf or .jpg format) to us at email@example.com
Alternatively, send a paper copy by post to:

* Remember to tell us which address the plan relates to.
You don’t need to provide any letter or additional detail with your plan.
