How do I know if it is my drain that is blocked?
If your drain is blocked you will usually know because your waste will stop going away when you flush the toilet, or gullies outside will overflow. There will also probably be a smell.
Blocked drains to private properties
It is the responsibility of the owner to maintain and clear a private drain. If a private drain is blocked, the council will serve a notice on the owner giving them 48 hours to clear it. If the drain is not cleared within 48 hours, the council will undertake the work in default. The owner will be charged the contract cost plus establishment charges of 30 percent.
To report a drain or gully that may be blocked or broken, you need to register or log in to My Account and then select ‘Add a Report’, then select the correct category from the drop down menu.
