Waste which contains grease shall be discharged into the sanitary sewer system only under the conditions of this chapter. The following facilities shall discharge all waste from sinks, dishwashers, drains, and any other fixtures through which grease may be discharged, into an adequately sized, properly maintained and functioning grease interceptor before the discharge enters the sanitary sewer. The following facilities shall also provide a grease-interceptor(s) inlet- flow control device inspection port and a grease-interceptor effluent monitoring port: new construction.
(a) Every commercial food-preparation and food-service facility including but not limited to bakeries, boardinghouses, butcher shops, cafes, clubhouses, commercial kitchens, delicatessens, fat-rendering plants, ice-cream parlors, hospitals, meat packing plants, restaurants, schools, slaughter houses, soap factories, and similar facilities, especially where meat, poultry, seafood, dairy products or fried foods are prepared or served;
(b) All shopping centers that have food-processing, facilities;
(c) All food courts;
(d) All other facilities discharging grease in amounts that the City determines may, alone or in combination with other substances from the discharges of the same or other facilities, inhibit the flow in the sanitary sewer;
(e) All new areas of intensified use or dwelling, including, but not limited to adult day- care facilities, assisted-living facilities, convalescent homes, day nursing and childcare facilities, in which food preparation occurs, homes for the mentally challenged, hotels, maternity homes, motels in which there is a commercial food- preparation service, nursing homes, retirement and life-care communities and homes, and truck stops with commercial food service, shall be required to have grease interceptors. Modifications to existing facilities that do not add new buildings or new grease-generating activities are exempt from this requirement.
Interceptors shall not be required for the following living quarters: single-family residences, duplexes, triplexes, and apartment complexes, unless the City first determines there are discharges from the property that may create problems in the sanitary sewer system. The determination shall be made based upon an investigation of the property and a comparison of the content and amount of discharge from the property with the discharges of other properties similar in size and use. Upon a determination that the discharges may create problems in the sanitary sewer system, the City may require the installation of a sufficiently sized grease interceptor to treat the discharges.
