Blocked drains

Private property issues

Drains, including manholes, that are on private property are the responsibility of the property owner, this includes blocked drains. Harrow Council is not responsible for such issues and will not be able to help.

Sewers are the responsibility of Thames Water as they are the sewerage authority in the borough and are responsible for the public sewers. This includes foul and surface water sewers.

If you have a blockage with your foul or surface drain, it is advisable to contact Thames Water. They can check their assets which connect to your property, and can clear those assets if necessary.

Highway drainage issues

The council is only responsible for the highway surface water drainage. This primarily means the roadside gullies and the gullies on the footways that are maintained by the council.

If you have spotted a blocked roadside or footway gully, please report this using the button below:
