Cooking instruments hanging in commercial kitchen Grease interceptors are an essential component of any commercial kitchen, cafeteria, or large-scale cooking operation. Their role is to remove fats, oils, and grease (FOG) from your wastewater before it enters the local municipal wastewater system, helping prevent hazardous backflow and environmental concerns.

Oregon Oils, serving Oregon and Southwest Washington, offers a full lineup of professional grease interceptor services, including educating clients on how their interceptor works. Learn more about the importance of your grease interceptor and the ways our team can ensure it serves its purpose.

How Does A Grease Interceptor Work?

Municipal wastewater systems are delicate and are not designed to handle FOG. A grease interceptor collects harmful substances and filters them out to allow wastewater to run freely. Typically made from concrete, interceptors are located in between kitchen drain lines and sanitary sewer lines. The collected FOG is housed in either above-ground or in-ground storage tanks.

Once wastewater enters the interceptor’s primary tank through the inlet pipe, it begins to cool. This causes any FOG to solidify. When FOG hardens, it will float to the surface of the water. Any debris found in the wastewater will make its way to the bottom of the interceptor. This leaves a middle layer of water that’s free of FOG.

The water then travels to the interceptor’s secondary tank which is separated by a crossover pipe. FOG that has made its way into the secondary compartment will rise to the surface. The filtered wastewater below is finally drained through an outlet pipe and is safe for discharging into the local sewer system.

There are two primary types of grease interceptors:

Hydromechanical Grease Interceptors (HGI)

These grease interceptors are installed either indoors above or below the floor, or outside underground. The capacity of this grease interceptor ranges and is dependent on the client’s needs.

Gravity Grease Interceptors (GGI)

These devices separate FOG from wastewater in large tanks that range in size from 1,000 to 4,000 gal. They are installed outdoors either aboveground or underground.

The Importance of Grease Interceptor Maintenance

Grease interceptors can endure a variety of problems that can cause them to perform less efficiently, resulting in FOG bypassing and entering sewer lines. This makes the need for proper maintenance and upkeep critical.

Interceptor lines can easily become clogged, cracked, damaged, and more. Failure to address these concerns can lead to a host of unwanted consequences, such as drain line blockages, back-ups, foul odors, and loss of business.

What’s even worse, a FOG obstruction in a grease interceptor can impact everyone around, causing a sewage overflow to the environment or into nearby properties. This means contaminants may enter local water supplies and eventually the atmosphere and affect wildlife.

City employees are responsible for inspecting a commercial kitchen’s grease interceptor to ensure it’s in good working condition. If commercial establishments are found not properly maintaining their grease interceptor, they could face several fines and citations, as well as be liable for any damages caused to other impacted homes or businesses.
