Grease Interceptors
How it Works
All Food Service Establishments (FSEs) must havea grease trap or grease interceptor. If you hold a food establishment permit from the city, you are a FSE and are required by city code to have a grease interceptor or trap.
Grease interceptors must be maintained andinspected regularly. The minimum required pumpout frequency varies from city to city, but remember, this is just a minimum and your grease trap should be pumped out when it becomes 25% full of solids and grease.

A grease interceptor is a pretreatment device thatholds or traps grease, food solids, and oils discharged from a Food Service Establishmentprior to entering the sanitary sewer. Greaseinterceptor sizes must be in accordance with yourcity’s ordinances. For more information, please visit:

The 25% Rule
Most cities require you to have a permitted hauler pump out your grease interceptor on a regular basis, but this is only the minimum requirement and does not guarantee that your grease interceptor will function properly for that length of time and prevent a grease overflow.
A good rule of thumb, and required by many cities,is the 25% rule, or having your grease interceptor pumped out when it becomes 25% full of solids and grease.
Example
Does this example meet the 25% rule?
Total FOG on top of interceptor = 0.5 ft.
Total solids at bottom of interceptor = 1.0 ft.
Total depth of interceptor contents = 4.0 ft.
Percentage of FOG + solids:
(FOG + Solids)Depth of
interceptor contents
(0.5’ + 1.0’)4.0’ == 37.5%
Answer: No, the 25% Rule has been exceeded and the FSE needs to increase their pump out frequency.
Best Management Practices To Maintain Your Grease Interceptor
Scrape food into the trash.
Avoid using the disposal.
Use sink strainers.
Wipe greasy utensils and dishware with paper towels before washing.
Recycle fry oil and cooking grease.
Bacterial and enzyme products will not decrease your pump out frequency.
Keep manifests on site for 3 years.

Verify that your liquid waste transporter has a permit to operate in the citywhere your business is located.This information should be available on the city’s website.
FSEs are required to witness every greaseinterceptor clean out and retain themanifest records for content removal for the speci�ed number of years.
