Grease Trap Perth Installs


What is a Grease Trap?

A grease trap is a holding tank designed to stop grease and solids from entering wastewater disposal systems, by separating the fats and grease from water.

Fats, oils, and grease accumulate over time, meaning your grease trap will require regular servicing and maintenance.

Any business that cooks or serves hot food is required, by the Water Corporation to have a grease trap, all wastewater from food preparation areas, floor wastes, kitchen sinks, and dishwashers are legally required in WA to flow directly into the grease trap.

Types of Grease Traps

The type of grease trap required by your business depends on their use and location. They come in the following options;

  • Concrete or plastic
  • Trafficable lids (motor vehicles) or non-trafficable lids (foot traffic)
  • Above or below floor installations
