Drains, gullies and sewers

Gullies (roadside gutters and drains) collect water running off the road and over pavement kerbs so it can go down drains into the sewer system and we are responsible for ensuring that road gullies are kept clean and running.

Gullies can become blocked and overflow through leaves, debris and grit collecting in the gully pot. This can lead to roadside flooding.

We do not maintain gullies on private roads. However to arrange a quote from us to come and clear them please email highwaysandinfrastructure@brent.gov.uk

We also respond to emergency requests to unblock gullies that are causing floods.

Ground water

Land Drainage is a complex area of responsibility. The general approach is that the landowner is responsible for the land drainage of their land. As Lead Local Flood Authority the Council has a role in providing technical advice with regard to local flooding sources so, we can provide advice to Residents of the borough who are having issues with groundwater. Please email highwaysandinfrastructure@brent.gov.uk 

Highway Drainage


On a main river the authority is the Environment Agency.

On any other watercourse, the authority will be either your lead local flood authority or the internal drainage board. 

You may be responsible for maintaining and repairing a flood defence on your land. Check with the Environment Agency by contacting 03708 506 506
