A grease trap is a device that is installed inside the building or under the sink. Grease traps will separate and retain fats, oils and grease and solid materials from the waste stream while allowing the rest of the liquid to discharge to the sewer using gravity. Baffles in the grease trap retain the wastewater long enough for the grease to solidify and float to the surface. Grease traps have a removable lid on the top to make grease trap cleaning and inspection easier.
Skim any trash along with the floating solidified grease and remove from the grease trap. Place collected grease solids and debris into a trash bag lined container.
Once all the floating fats, oils and grease, and trash have been removed from the grease trap, carefully bail, or scoop out the water. Collect this water into a water tight container that is separate from the collected grease container as you are going to be returning this effluent water back into the grease trap once you have finished cleaning.
Remove the solids at the bottom and place in a water tight container. The baffle and inside walls should be removed, scraped, and cleaned to remove any grease buildup. Dispose of scraped grease and solids into the trash, and not the grease trap.
Once the inside of the grease trap is fully cleaned, replace the baffle, and carefully pour the collected water back into the unit.
Replace the lid and tighten to ensure a tight seal. Always remember the importance of grease trap cleaning and the role it plays in the prevention of fats, oils and grease within the public sewer system.
Grease trap maintenance is a key component to a successful FOG Program.
