Frequently Asked Questions

What are Grease Traps and Grease Interceptors?
Grease traps have been used since the Victorian days. They are used to reduce the amount of fats, oils and greases (FOG’s) that enter the main sewers. Effectively they are boxes within the drain run that flows between the sinks in a kitchen to the foul sewer system. They only have waste water flowing through them and are not served by any other drainage system such as toilets. They can be made from a number of different materials; e.g. Stainless Steel, Plastics, Concrete & Cast Iron. They range from 35 litre capacity to 45,000 litres and above capacity. They can be located above ground, below ground, inside the kitchen or outside the building.

What happens to the grease?
The trapped grease is stored in the trap until it is cleaned out.

Do I need a Grease Trap?
Most Local Authorities require a system to prevent grease and fat from flowing into the main sewerage system. Even if it is not required, you may want a Grease Trap to help prevent clogged drains from stopping work.

How does a Grease Trap or Grease interceptor work?
By slowing down the flow of hot greasy water and allowing the grease to cool. As it cools, the fat, oil and grease separate and float to the top of the Grease Trap. The clean water continues to flow down the waste pipe.

What happens if I don't have a Grease Trap or Grease Interceptor?
Drains block and waste water backs up. Even partial drain blockages can cause floor drains to back-up, causing pollution. Also, this stops work and may require expensive maintenance.

What else can I do to prevent blocked drains?
Fat, oils and grease cling to other solids in your waste water. Minimising the solids and food particles going down the drain will decrease the risk of blockage.
