A. All food establishments shall install a grease pretreatment device in the waste line leading from the food preparation area, or from sinks, drains, appliances and other fixtures or equipment used in food preparation or cleanup, to where grease may be introduced into the sewerage system. Such grease pretreatment devices shall be installed to remove grease from wastewater and shall be maintained in efficient operating condition by periodic removal of the accumulated grease. No such collected grease shall be introduced into any drainage piping or public sewer.

B. All food establishments shall also provide a collection drum or container for the purpose of physically segregating oils, greases and greasy solids. Food establishments shall establish procedures for personnel to practice maximum segregation of oils, greases and greasy solids to the collection drum or container prior to washing and other cleaning which goes into sewer. Food establishments shall properly remove and appropriately dispose of the material captured from grease pretreatment devices on wastewater lines and the collection drums for segregating oils, greases and greasy solids. (Ord. 2466 § 7, 1991).
