We maintain the roadside surface water drains (also called gullies) which allow rain water to run away freely from the road and highway.
Roadside surface water drains are normally found in the kerbside channel or highway gutters.
If a roadside drain becomes blocked it could cause local flooding in that road. We clean the roadside drains regularly to prevent them from being blocked:
- drains on unclassified* roads are cleaned once every year
- drains on classified roads are cleaned twice every year
Flooding after heavy rainfall
- After heavy rainfall some drains can become overwhelmed and drain slowly, this can cause flooding in some areas.
- If this is the case then please wait for a few hours after the rain has stopped before reporting this to us.
Report a blocked roadside drain
If you notice that roadside drain has become blocked by leaves or rubbish and the blockage can be easily removed, without putting yourself or others at risk, then it may be quickest to push the blockage to one side yourself.
If you think this is an emergency then please call us on 0208 547 5002.
What we do
- When tackling a blocked drain we first try digging out the blockage or using water jets to release the blockage.
- If this is not possible because the grating is broken, there is a tree root in the way or the pipe is broken - we will refer the matter to the relevant agency, eg highway maintenance, Thames Water or a specialist outside contractor for further works.
