GREASE
Material composed primarily of fats, oil, and grease (FOG)

products.
GREASE TRAP
A device for separating and retaining waterborne greases
and grease complexes prior to the wastewater exiting the trap and

devices also serve to collect settleable solids generated by and from
food preparation activities, prior to the water exiting the trap and
entering the sanitary sewer collection and treatment system.
OIL/WATER SEPARATOR

designed and manufactured to separate oil from water. The system shall
allow the oil to be collected and removed on a regular basis as to
prevent it from being discharged into the wastewater collection system.
Only oil/water separators manufactured for that specific operation
will be approved. Adequate support literature from the manufacturer
will be required so as to allow a proper review by the Building Inspector.

the jurisdictional limits of the City, who contributes, causes, or
permits the contribution or discharge of wastewater into the City's
