We are responsible for cleaning drains on the public road.
A drain is made up of an iron grate set in the road with a pot underneath (see images 1 and 2). It has an outlet pipe attached to take water into the main drainage system. The pot collects any debris, leaves, litter, soil and rubbish that is washed off the road ensuring that the collecting pipe doesn't become blocked.
Please report broken or missing drain coversto us immediately using the general highways form and giving a precise location as possible.
A culvert is a pipe-like structure that channels the flow of a stream beneath a road.
A pipe that carries surface water is often referred to as a drain. A culvert normally refers to a structure larger than a pipe but smaller than a bridge of the type where a brook, stream or river flows beneath a road.
We clean over 180,000 drains at the side of roads each year. The majority are cleaned once a year however in known problem areas and on major roads we clean them more frequently. We don't clean drains in car parks, blocks of flats or private roads.
More information on excess water can be found on our flooding pages.
