A grease trap system is designed to substantially minimize the amount of the fats, oils, greases and food solids that flow out of the grease trap into the septic system or sewer. Essentially, when wastewater enters the grease trap and begins to cool down, the fat, oil and grease begin to harden and float to the top, as they are lighter than the wastewater. The food solids float down, settling to the floor of the grease trap and continuously build up. The wastewater is forced through the grease trap and out to the septic system or sewer.
It’s generally recommended to have the grease trap cleaned out at least every 90 days and more often for high-volume kitchens and businesses. Not having regular maintenance performed on your grease trap can cost your restaurant or business thousands of dollars in lost revenue, lost customers and can cause a temporary shutdown.
