A drainage interceptor is a specialist tank designed to reduce the risk of pollutants entering drainage systems, sewers or natural watercourses. It captures materials such as oil, fuel, grease, silt and heavy solids from surface water runoff before the water continues through an approved drainage route.

A sewage tanker is used to collect, transport and dispose of liquid waste from sites where waste cannot remain in storage or be managed through standard drainage. These vehicles are commonly used for septic tanks, portable toilets, welfare units, commercial drainage systems, grease traps, sludge tanks and industrial wastewater.
