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.
