Blocked drains/gullies

How we maintain gullies

Highways’ road gullies, in identified Critical Drainage Areas (CDAs) of the borough, are cleaned annually by a cleansing vehicle.

Any reported blockages of gullies, through our Our Haringey/Love Clean Streets app, officers’ regular highways inspections or by the public and Councillors, are subsequently cleaned by our highways contractor as a part of a reactive gully maintenance programme.

Generally, road gullies connect to Thames Water sewers, which are either surface water only or are combined sewers that carry surface water and foul drainage. The effectiveness of the gullies, particularly in intensive storms, is dependent upon the capacity of the Thames Water Sewers.

How do I know if it is my drain that is blocked?

If your drain is blocked you will usually know because:

  • Your waste water will stop going away when you flush the toilet or empty a sink/bath
  • Private gullies (those outside your home, but still on your property) 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 can 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%.

Cyclical gully cleansing programme

We are now working on our annual cyclical gully cleansing programme for completion by 31 March 2024.

We are planning to carry out cleansing works across the following wards:

September 

  • Crouch End
  • Muswell Hill
  • Crouch End
  • Northumberland Park

October 

  • Northumberland Park
  • Crouch End
  • Tottenham Hale
  • Seven sisters

November 

  • Crouch End
  • Tottenham Hale
  • Hornsey
  • Tottenham Central
  • Bounds Green
  • South Tottenham

December 

  • Tottenham Central
  • Stroud Green
  • West Green
  • Highgate
  • Hornsey
  • White Hart Lane

These works require extensive planning, so parking suspensions will be in place to make sure we are able to carry out this work. Parking suspension noticeboards will be placed on roads in advance of the proposed works.

As part of this cleansing programme, we will also carry out several highway drainage improvements and immediate maintenance works.

The proposed gully cleansing programme is targeted to where it is most needed. For example, areas with recorded floods and main roads will be cleansed more often than those areas where there are no reported gully drainage issues.

Emergency gully cleansing

We will carry out any emergency gully cleansing throughout the year and this will work in parallel with the cleansing programme.

Please note that it is likely we will have to put some parking suspensions in place before emergency work can be carried out.

What happens once I have submitted the report?

We will inspect the problem within two working days and decide how urgently it needs to be fixed.

How long should it take?

Defects that are hazardous or serious will be prioritised. Hazardous defects will be repaired within 24 hours. Serious defects will be repaired within 7 days. We will aim to repair other defects that are not serious or hazardous within 28 working days, but we do not have the resources to repair every defect within that timescale and so will prioritise the more serious and potentially dangerous defects.

How will I be kept up to date?

We will contact you by email to let you know the result of the inspection and again when the repair has been completed.
