Professional Grease Trap Cleaning That Keeps You Compliant

The most reliable indicator is the depth of the grease cap sitting on top of the water inside your trap. If it exceeds twenty-five percent of the total trap depth, you are likely due for service and may already be out of compliance. Practical warning signs in your kitchen include slow-draining sinks, foul odors coming from floor drains or the trap area, and grease backing up into sinks or onto the floor. If you notice any of these, do not wait for your next scheduled cleaning — call us to move your service date up. Ignoring the warning signs risks a sanitary sewer overflow, which can result in significant fines from your local sewer authority and a very unpleasant cleanup situation in your kitchen or parking area.

A grease trap is typically a smaller unit installed indoors, often under a three-compartment sink or near the dishwasher. These units range from about twenty to one hundred gallons and handle lower volumes of FOG. A grease interceptor is a larger unit installed outdoors, usually underground in the parking lot or near the building exterior. Interceptors range from five hundred to several thousand gallons and are designed for high-volume kitchens. We service both types using the same thorough cleaning process. The main difference in service is time and equipment — interceptors take longer to pump and require a larger vacuum truck. Regardless of which type your kitchen has, the cleaning frequency depends on accumulation rate rather than physical size alone.

We schedule all grease trap cleanings during your slowest hours to minimize disruption, and most operators choose early morning service before the lunch rush begins. For indoor traps, the technician needs access to the trap and the nearest sink for about thirty minutes. During that window, you should avoid running water through the drains connected to the trap. For outdoor interceptors, kitchen disruption is minimal because the work happens entirely outside. The only thing we ask is that you reduce heavy drain usage for about fifteen minutes while we test flow at the end of the service. Most kitchen teams tell us they barely notice we are there. We coordinate the schedule with your manager ahead of time so everyone knows what to expect.

If an inspector measures your grease cap and it exceeds the allowable threshold — typically twenty-five percent of total trap depth — you will receive a FOG violation notice. Depending on your jurisdiction, the first offense usually comes with a written warning and a required corrective action, which means getting your trap cleaned immediately and providing proof of service. Repeat violations escalate to monetary fines that can range from two hundred to five thousand dollars or more per incident. In severe cases, the sewer authority can mandate a more frequent cleaning schedule at your cost or require you to install a larger interceptor. The simplest way to avoid this entirely is to maintain a regular cleaning schedule with documented records that demonstrate ongoing compliance.

Yes. All grease trap waste we collect is transported to licensed disposal and processing facilities in full compliance with local and state regulations. We maintain detailed manifests for every load that document the origin, volume, date, and receiving facility. Unlike some unlicensed operators who illegally dump waste into storm drains or unauthorized locations, we follow a fully documented chain of custody from your trap to the processing facility. This matters because as the generator of the waste, your restaurant can be held liable if your hauler disposes of it improperly. By using a licensed service with verifiable disposal records, you protect your business from potential environmental fines and liability claims.

In most cases, yes. If your grease trap cleaning and cooking oil pickup fall on the same schedule, we coordinate both services into a single visit so you only deal with one truck and one appointment. This is especially convenient for busy kitchens that do not want multiple service vehicles showing up on different days. The combined visit typically takes forty-five to seventy-five minutes depending on your trap size and oil volume. Both services generate their own separate documentation — a grease trap service report and a CDFA oil manifest — but everything is accessible from the same online dashboard. If your cleaning and pickup schedules do not align naturally, we can adjust one or both to synchronize them at your request.
