A Hydro-mechanical Grease Interceptor is a device that separates nonpolar FOG such as fats, oils, and grease from wastewater discharge.
Show All Answers
FOG stands for Fat, Oils, and Grease. When it is poured down drains, it can harden and create blockages in the wastewater system.
Grease Interceptor is a device located on the outside of the building meant to separate FOG from the wastewater discharge. There are at least two chambers separated by a baffle.
A Gravity Grease Interceptor is required for businesses or commercial establishments that discharges grease, fats, or oils such as restaurants, food service facilities, and stores that sell food they cook on premises as seen in City Ordinance Section 82-140.
The frequency the Grease Interceptor needs to be cleaned is based on the unit itself. The suggested pumping and cleaning intervals are listed below; however, some may need to be scheduled more frequently.
It should not exceed 90-days, or if the following occurs:
1. When the floatable grease layer in the outlet side (measured by an approved dipping method) exceeds 6 inches in depth
2. When the settable solids layer in the outlet side (measured by an approved dipping method) exceeds 8 inches in depth
It should not exceed 7-days, or if the following occurs:
1. The total volume of grease and solid material displaces more than 20% of the total volume of the unit.
BSI will generate the frequency of when the interceptor will need to be cleaned and pumped. If the business/property owner needs to alter the frequency, please reach out to the Utility Department.
The cleaning and pumping of the Grease Interceptor are to be reported to Backflow Solutions Inc, or BSI.
Backflow Solutions Inc, or BSI, is a company partnering with the City of Fernandina Beach to help record the frequency of the cleaning and pumping of the systems. They are available for assistance on their website: backflow.com, or by phone: (800) 414-4990.
The business/property owner can use any certified hauler for cleaning and pumping the Grease Interceptor.
The business/property owner will have six months to come in compliance. If they have any questions or concerns, please feel free to contact the Utilities Department.
The business/property owner is responsible for ensuring that either they, or the hauler, report that the unit has been pumped and cleaned.
