1008.1 Drainage from commercial garages, gasoline filling stations, dry cleaning establishments, oil extraction plants, and other industries where oils or solvents are used, is likely to contain inflammable compound, which shall therefore be intercepted before discharging into the public sewer. The interceptor shall have a capacity sufficient to separate the oil, grease, or other inflammable compound and shall be so located and constructed to prevent fire or explosion. Drainage from commercial garages and oil stations where automobile wash racks are installed is also likely to contain mud and sand which shall be separated from the wastes before discharging into the public sewer. Hence, the interceptor for these wastes shall afford sufficient capacity for both separating the oils and grease by flotation and the sand and mud by settling.

1008.2 Where the wastes do not contain sand, mud or other solid material and inflammable compounds only are to be separated, the interceptor shall have a minimum capacity of 15 cubic feet with a minimum effective depth of 3 feet; and shall be provided with a vent and manhole with tightly fitting cover.

1008.3 For drainage from commercial garages or other places where wastes are likely to contain sand, mud, or other solid material in addition to oil, grease, or other inflammable compounds, a minimum capacity of 50 cubic feet, with a minimum effective depth of 3 feet, shall be provided and a vent and manhole with tightly fitting cover shall be installed.

1008.4 All interceptors shall be cleaned periodically.

1008.5 Interceptors shall be built of poured concrete with floors and walls not less than 5 inches thick. Covers shall be of poured, reinforced concrete not less than 5 inches thick.

1008.6 Subsections 1008.1 through 1008.5 of this section shall apply except for manufactured or prefabricated concrete interceptors that comply with approved applicable standards. See “Exhibit A. Commercial Mud Trap”.

1008.7 For details, see diagram marked “Exhibit B. Mud Trap or Inflammable Waste Interceptors”.

15.15.490 Amendment to UPC 1012, Grease Interceptors for Commercial Kitchens.

Section 1012, Grease Interceptors for Commercial Kitchens, is amended by adding the following subsections:

1012.1 Any licensed food establishment shall install and maintain an outside interceptor and shall have all kitchen equipment discharge through such interceptor. The drawing marked “Exhibit C. Commercial Kitchen Grease Interceptor” is the recommended method of installing an outside interceptor.

1012.2 These interceptors shall be not less than two compartments with fittings designed for grease retention. The inlet, outlet and compartment fitting shall be of the elbow type design with the vertical lead extending to within 12 inches of the interceptor floor. The fitting shall not be less than 4 inches or the size of the building sewer, whichever is greater.

1012.3 The vent opening above the fittings shall allow the interceptor and sewer to vent back to the building vents, thus no vent is required on the outlet end of the interceptor. A clean out is required on the outlet line, outside the tank.

[Ord. 46 § 48, 2000. Code 2009 § 4-4-48.]

15.15.500 Adding to UPC 1014, Residential Garage Interceptor.

15.15.520 Exhibit A.

The following drawing is an approved type of manufactured or prefabricated concrete interceptor.

Mud trap sidewalls and floor are reinforced with No. 3 rebar: side walls and the compartment divider are two and one-half inches thick; the floor of the mud trap is three inches.

The lid is reinforced with over 20 feet of No. 4 rebar, and is five inches thick.

Capacity of the mud trap is a nominal 625 gallons; if capacity is calculated at a conservative 500 gallons, the volume of the inlet compartment is still 0.9 cubic yards, and the outflow compartment has a volume of 1.8 cubic yards.

[Ord. 53 Art. 2, 2000; Ord. 46, 2000.]

15.15.550 Exhibit D.

The drawing below is the recommended method of installing a drain in a residential garage. No dimensions are shown, just the required one cubic foot per each compartment. Also, the outlet of such a drain must be vented.
