We are responsible for the gullies, or road drains as they are sometimes called, which are located on the public highway. These gullies collect the water running off the road and pavement areas.
Gullies are usually located at the edge of the kerb where the road meets the pavement and have a metal grill as a cover. Sometimes these grills can become blocked with mud or leaves and prevent the water draining. Also, on occasion the gullies get blocked or cannot handle the capacity of water flowing and overflow onto the road.
Report a blocked drain or gully
The following give guidance on who to contact for various types of flooding on the highway.
Flooding on the public highway

Flooding from public sewers
The water company own and manage the network of public foul and surface water sewers. The majority of public sewers are located in the highway and we have a copy of the sewer maps, which can be viewed at the Council Offices. To report an overflowing public sewer, you should contact Thames Water freephone leakline on 0800 714 614.
Flooding from private sewers or drains
If your private drains or sewers are overflowing, you will need a drainage contractor to deal with any blockage. (see "Yellow Pages" or similar local directories). If you are uncertain if any blockage is in the public or private sewers, Thames Water should be able to determine this, once on site. They will recharge you the cost of any work on the private sewers.
