C. Grease interceptor sizing criteria
V (min) = FxRxS
Where:
• V(min) = Minimum Gravity Grease Interceptor Operating Volume, gallons
• F= Flow Rate (maximum), gallons per minute
• R= Retention Time = 30 minutes
• S = Storage Factor = 25%
{00033691.DOCX /}
Exhibit A
Thus: V(min) = F x 30 x 1.25 %
The flow rate shall be determined based on the total flow rate from all equipment and
plumbing fixtures connected to the gravity grease interceptor using one of the following
equations:
Drainage Fixture Units (DFU) less than or equal to 40: F=(0.8xDFi�
Drainage Fixture Units greater than 40: F=(0.3 x DFU) + 20
Where: DFU = Drainage Fixture Units per Table 709.1
• The mi_nimum retention time of 30 minutes is based on Wastewater Engineering,
Treatment, Disposal and Reuse, Third Edition, Metcalf and Eddy, Inc. McGraw-Hill,
Inc., page 1028
• A minimum of 25 % storage is required for floatable fats, oil and grease and
settled solids is required for gravity grease interceptors.
• The minimum sized GGI to be installed shall be 3Q0 gallons
Note: Providing additional interceptor capacity can reduce an interceptor's
maintenance frequency. However, solid accumulation and low flows in an interceptor
can, over an extended period of time, produce a corrosive environment which can
damage the structural integrity of the interceptor. An oversized intercept�r may also
generate odor problems.
