Grease Traps: Everything You Always Wanted to Know (and More!)



Remember the London fatberg story?

Sorry if you were trying to put it out of your mind.

As you might recall, in August 2013 sewer workers in London discovered a double-decker-bus-sized mass of grease and wet naps, which was immortalized in the tabloids as “fatberg.” The berg had nearly blocked the entire 7-foot diameter pipe. Had it fully blocked the pipe, residents of the London borough of Kingston would’ve been in for a MOST UNPLEASANT surprise.

“The sewer was almost completely clogged,” sewer worker Gordon Hailwood told the Guardian. “If we hadn’t discovered it in time, raw sewage could have started spurting out of manholes across the whole of Kingston.”

The 15-ton London fatberg incident is a great illustration of the unheralded importance—to our infrastructure and to our public health—of grease traps: those toolbox-sized containers that commercial kitchens put below their sinks. The purpose of grease traps, also known as grease interceptors, is to reduce the amount of fats, oils and greases (FOGs) that enter our sewer systems.

As anyone who has cooked bacon knows, grease congeals when it cools, and can cling to and eventually clog your pipes if you pour it down the drain. The London fatberg incident shows what happens, on a macro level, when too much grease oozes into the public sewer system. Because when too much grease accumulates in the sewer, raw sewage has nowhere else to go but … everywhere.

According to data from the Environmental Protection Agency, sewers back up an estimated 400,000 times each year due to pipe blockages, and and grease is the primary culprit, resulting in over 10 billion gallons of raw sewage spills each year.

So, the moral of the story? Grease traps are a VERY good thing that EVERYONE benefits from, and that’s why virtually every municipality requires their use in commercial kitchens to prevent FOGs from clogging public sewer lines.

That said, not all grease traps are created equal! To ensure that your device not only does the job but proves durable over the long run, head over to eTundra.com and shop of wide selection of top-of-the-line grease traps!
