How often do I need to clean out the Grease Interceptor?

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.

>50-gallon capacity

    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 

<50-gallon capacity

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.
