Australia grease trap cleaning – how do grease traps actually work?


A grease trap is a simple plumbing device to prevent the city drain lines from becoming blocked up.


As per WikipediaGrease traps have been used since the Victorian days, although Nathaniel Whiting obtained the first patent for a modern-day grease trap in the late 1800s.


They are used to reduce the amount of fats, oils and greases (FOGs) that enter the main sewers. Effectively they are boxes within the drain run that flows between the sinks in a kitchen to the sewer system.


They only have kitchen waste water flowing through them and are not served by any other drainage system such as toilets.”


“In the United States, sewers back up annually “an estimated 400,000 times, and municipal sewer overflows on 40,000 occasions”.


The EPA has determined that sewer pipe blockages are the leading cause of sewer overflows, and grease is the primary cause of sewer blockages.”


“When the outflow from the kitchen sink enters the grease trap, the solid food particles sink to the bottom while the lighter grease and oil floats to the top.


The relatively grease-free water is then fed into the normal septic system. The food solids at the bottom and floating oil and grease must be periodically removed in a similar manner as with septic tank pumping.”


“Waste from passive grease traps and gravity interceptors is referred to as brown grease. Brown grease is rotted food solids in combination with fats, oils, and grease (FOG).


Brown grease is pumped out of the traps and interceptors by grease pumping trucks. Unlike the collected yellow grease, the majority of brown grease ends up in landfill sites.”


Australia Grease trap cleaning involves having a trusted contractor with a large liquid holding truck come to your facility. The truck pumps the complete contents of the grease trap back into the truck’s tank (i.e. all liquid in the trap  i.e. all grease and water).
