Grease interceptors are used in plumbing systems to trap greases, oils and solid particles before they can reach the public sewage. For this reason, they are also known as grease traps. A certain oil content is normal in wastewater, and it forms a thin floating layer once it reaches septic tanks and water treatment facilities. However, wastewater from food preparation contains more oil than in other applications, and the waste from multiple commercial kitchens can overwhelm water treatment systems and cause spillage. Lard and other high-viscosity fats can also solidify as they cool down, trapping other solids and blocking sewage pipes.
