4 comments | Gullies can become blocked with materials such as litter, oil, fat and concrete, which blocks water from entering the drain pipes below. This can then lead to flooding on pavements and roads above. To deal with this problem, we have 2 gully cleaning machines that act as a vacuum, removing blockages from the gully to keep the system running smoothly. Our crews clean and unblock gullies across the city on a daily basis - find out how it works: | Manchester City Council | Facebook
