Grease Traps Help to Clear the FOG

Grease TrapsDo you know what a grease trap is? It’s not your local fast food chain, though the restaurant may actually have one. A grease trap is a plumbing device that helps to block the fats, oils, and greases (FOG) from entering into your sewage system.

All waste water contains some amount of grease in it. When it enters the septic tank, the grease rises to the top of the tank and forms a layer known as scum. This layer is then slowly broken down by the bacteria found in the tank. A little is unavoidable, but too much FOG in the tank can take too long to break down and cause overflow, possibly resulting in toxic septage being released. Restaurants and kitchens with high food production require grease traps to keep as much oil out of the septic system as possible.

A grease trap is basically a box that is in the drain in between the kitchen and the sewer lines. The waste water from the kitchen enters the grease trap and then begins to separate. The solids sink to the bottom; the fats, oils, and greases rise to the top; and the water in between (which is relatively clean) is then fed through to the main sewer lines and eventually into the septic tank. The grease trap effectively works as a mini septic tank separating the waste water.

Just as a septic tank requires occasional pumping, grease traps require cleaning to get rid of the solids that sink to the bottom. While you can clean grease traps by yourself, it is a big task and may be better done by a professional.
