Continued. All the fixtures and floor drains in hotels, kitchens, restaurants, cafeterias, drive-ins, hospitals, schools, and other public places where food is prepared or cooked, may waste into one grease interceptor that is vented as heretofore specified and each fixture wasting into this grease interceptor shall be trapped and vented as specified in this ordinance. To determine the proper size of the waste lines to this grease interceptor the fixture unit value as specified in fixture unit table of this ordinance shall be used. The total number of fixture units wasting into the grease intercep- tor shall determine the proper size waste line and the inlet and outlet of the grease interceptor shall not be smaller than the line wasting into it. For calculating the required sizes of grease interceptors the rate of discharge from each fixture connected to the interceptor shall be based up- on the rates shown in the fixture unit table. The grease retaining capacity of each grease interceptor, in pounds of grease, shall be equal to twice the rate of flow capacity in gallons per minute of waste water so that the inter- ceptor shall remove and retain 90% of the grease discharged into it up to its required capacity of accumulated grease. Unless otherwise approved by the Chief Plumbing Inspector, grease inter- ceptors shall separate grease while it is in the liquid state, that is, a separation shall be accomplished by differential gravity methods, assuming temperatures of waste at 1500 F. and a rate of rise of grease at 0.05t per second reduced to 0.025, per second to allow for turbulence. The Chief Plumb- ing Inspector shall establish detailed formulas for further determining the effectiveness of grease interceptors submitted for approval under these regu- lations and shall prepare and maintain a list of the interceptors which are approved.
