1.   A grease interceptor shall be installed in the waste line leading from sinks, drains or other fixtures in restaurants, hotel kitchens, cafeterias and food processing establishments, and in any bar, lounge, private club or fountain where food is prepared or served, or where dishes, glasses, pots, pans or other kitchenwares are washed, or any other establishment where grease or broken glass can be introduced into the drainage system in quantities that can effect line stoppage or hinder sewage disposal. Grease, oil and sand interceptors are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other ingredients harmful to the building’s drainage system, the public sewer or the municipal sewage treatment plant.
   2.   Interceptors shall not be required for private living quarters or residential dwelling units.
   3.   All interceptors shall be of a type and capacity as defined in the city’s current adopted Plumbing Code and shall be approved by the Municipal Building Inspector. All interceptors shall be located so as to be readily and easily accessible for cleaning and inspection. Such interceptors shall be properly inspected following construction, by the Municipal Building Inspector, and shall be privately maintained, at the owner’s expense, in continuously efficient operation at all times.
   4.   An oil separator shall be installed in the drainage system of any establishment where, in the judgment of the Municipal Building Inspector, a hazard exists or where oils or other flammables can be introduced or admitted into the public sewer by accident or otherwise.
   5.   All garages, filling stations and car washes having car wash racks or facilities shall install combination grit and grease interceptors.
   6.   All commercial laundries shall be equipped with an interceptor having a removable wire basket or similar device that will prevent strings, rags, buttons or other materials detrimental to the municipal sewer system from passing into the drainage system.
   7.   Bottling plants shall discharge all processed wastes into an interceptor which will provide for the separation of broken glass or other solids, before discharging liquid wastes into the municipal sewer or storm drainage systems.
   8.   Slaughterhouses shall equip all slaughtering room drains with a separator which shall prevent the discharge of feathers, entrails and other material likely to clog the drainage system.
   9.   All existing establishments listed in subsection 1. above shall have 90 days from the effective date of this code of ordinances to install an improved interceptor or separator. Establishments covered under subsection 4. above will be handled on a case-by-case basis to determine whether an oil separator is required. All establishments covered under subsection 1. above, constructed henceforth, shall include an approved interceptor.
   10.   The Municipal Building Inspector, Utilities Superintendent or Mayor shall have the right of entry during usual business hours, to conduct an inspection of an interceptor or separator.
   11.   Any person found to be in violation of this section shall be served with written notice stating the violation and providing 72 hours for the satisfactory correction thereof. The offender shall, within the period of time stated in such notice, permanently cease all violations. In the event an establishment is cited with a second violation within six months of the first, the time allowed for correction shall be reduced to 48 hours. A third citation within six months from the first violation will be cause for the city to immediately discontinue water service to the establishment, during which time the offender shall correct the violation.
   12.   Any person who shall continue any violation beyond the time limit provided for in subsection 11. above and upon conviction thereof, shall be fined in an amount not exceeding the limits established in Chapter 11, Article 3, § 50 of this code of ordinances for each violation. Each day in which any such violation shall continue shall be deemed a separate offense.
