Grease Trap


What Is A Grease Trap?

In simple terms, grease traps (unsurprisingly) trap grease. More specifically, it is installed to trap grease, oil and fat which flows through wastewater.

These traps are commonly found in commercial kitchens, and on the odd occasion there can be more than one installed in particular circumstances.

How Does A Grease Trap Work?

Waste containing fat, oil & grease (commonly known as FOG) enters the grease trap. Grease has a lower density than water by around 10-15%, and is unable to mix with water. As a result, the FOG will rise to the surface, and the grease-free water will pass to the main sewer drain.

Do I Need A Grease Trap?

Most local authorities may require you to install grease traps due to your business’ main occupation. This being said, not having a grease trap installed can become a costly subject to overlook.

One thing you want to always try and avoid is SSO. This stands for Sanitary Sewer Overflow. SSOs can commonly crop up when grease has solidified within the main sewer line and created a blockage. This will lead to a costly project of cleaning your drainage system.

A grease trap’s whole purpose is to avoid this situation.
