If you have a blocked drainage pipe, South West Water’s responsibility of clearing it is entirely up to whether it is a public drain or a private drain.

If the blocked drainage pipe is a private drain, it is the responsibility of the homeowner and not of South West Water. The recommendation is to contact an approved contractor or consult your insurance policy if you have one. WaterSafe provides a list of approved contractors who you can contact.

If the blocked drain is public, this is the responsibility of South West Water. You should call the South West Water emergency contact number on 0344 346 2020 for them to ascertain the situation. South West Water will arrive within 4 hours to unblock the sewer. You will not be charged for the unblocking.

If you are a tenant and are experiencing a blockage, you should get in contact with your landlord.

Depending on the type of blockage or flooding, the responsibility for the maintenance varies. Here is a list of the numbers and authorities who are responsible for dealing with different types of water-related issues:
