Improper discharge of fats, oils and grease into the sanitary sewer system is a leading cause of sanitary sewer overflows. The pretreatment coordinator reviews and approves pretreatment systems and sizing calculations to ensure that they are adequate for the fats, oils and grease to be discharged by food service establishments and vehicle maintenance facilities.
An applicant must obtain approval for a pretreatment system prior to submitting commercial building plans for new buildings, additions, change of use, alterations and interior completions at a food service establishment or vehicle maintenance facility.
- A food service establishment includes any commercial building that has a kitchen or food preparation area where grease-laden waste is drained into the sanitary sewer system.
- A vehicle maintenance facility is a place where automobiles are serviced, greased, repaired or washed. This includes automobile repair shops, engine repair shops, car washes and rental equipment washes.
