Grease Trap Installation

Commercial Grease Trap Installation and Maintenance Perth

Grease traps are unique devices located between the drainage lines of the source or point generating liquid waste and the sewer system, which allow the separation and collection of solid waste, grease, and oils from used water, preventing these materials from reaching the sewerage network. 

Grease traps are generally used in establishments where fat production is relatively high such as hotels, restaurants, hospitals, and other food production industries.

Grease Trap Installation Perth - Rowson Plumbing Services

The Function Of Grease Traps

A grease trap retains by sedimentation the suspended solids and by flotation the fat material. The goal of this is to allow wastewater to cool down. Once the grease and oils have cooled to the required temperature, they will float to the top of the grease trap, while other heavier solids are deposited at the bottom of the trap. The rest of the water passes freely into the sewer network.


The overall structure of a grease trap comprises three chambers. The input chamber, the output chamber, and separation structures in the middle of these two. Creating a third intermediate chamber in which grease and oils are retained. Water enters the first chamber, all floating material such as greases rises in the second compartment of the chamber as they are lighter (less dense) than water, solids at the bottom. Finally, in the third compartment of the chamber, grease-free clarified water comes out

Do I Need a Grease Trap for My Business?

Any business that operates in the food industry or serves hot foods in Perth is mandated by law to have a grease trap. The wastewater that flows from the food preparation or processing area must run into a grease trap.


Types Of Grease Traps



Floor or Underground Grease Traps: These usually have a greater hydraulic capacity and are made up of several compartments. They can be prefabricated and installed at a much cheaper cost compared to the other types. Additionally, these are effective and can remove up to 99% of fats. They can be found in gas stations, department stores, shopping centres, restaurants, etc.



Dissolved Air Float Grease Traps (DAF): These use mechanical skimmers to collect floating grease from the water surface. These equipment are more expensive and are often found in large industrial water treatment plants, with high fat and oil content
