Road-sweeping vehicles sweep the road channels (gutters) of most kerbed roads on a cyclical basis. This removes any grit, litter and general dirt that has collected there. During autumn, we suspend routine sweeping so that we can divert resources into clearing leaves.
In some roads, we have trouble sweeping the gutters because of parked cars. We deal with these roads by including them on a traffic management programme and writing to residents aking them to remove their cars on a specific day so we have access to the road channels.
