A gully sucker is a specialist vacuum truck designed to remove silt, sludge, and debris from roadside gullies, drains, and catch pits to prevent blockages and flooding. It is generally also part of a mechanical road sweepers capabilities.

Collected waste from gully suckers is typically transported to licensed facilities where it’s filtered, treated, and safely disposed of according to environmental regulations.

In the UK, highway authorities are legally responsible for maintaining road gullies, often using gully suckers under scheduled or emergency service contracts.

Regular gully sucking is part of preventive road maintenance, helping extend the life of drainage systems and avoid costly repairs or water damage.
