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. This includes foul and surface water sewers.
If you have a blockage with your surface or foul water pipes or drains, it is advisable to contact Thames Water. They can check their assets which connect to your property (not within your property), and can clear those assets if necessary. You may need to contact a private professional drainage company to inspect and clear the drainage within your property if Thames Water are not responsible.
Highway drainage issues
The Council Highway Authority is only responsible for the highway surface water drainage on roads that are maintained by the Council. This primarily means the roadside gullies and the gullies on footways that are maintained by the council.
Surcharging gullies is water that is flowing out of a gully. This is not due to a blocked gully but is a sewer capacity issue (hydraulical overloading). It means the sewer is full and can not drain any more water.
Report a blocked gully
Please send the following information by email to firstname.lastname@example.org:
- Location of the gully
- Description of the issue
- Photo of the issue (optional)
