1. An interceptor shall be installed in a user’s building sewer when in the opinion of the director it is necessary for the proper handling of wastewater containing grease or oil in excessive amounts, sand, grit or other harmful substances; except that such interceptors shall not be required for buildings used solely for residential purposes. Provided, however, that interceptors shall be constructed in any place or building having a capacity to serve group meals and in commercial and industrial cleaning facilities.
Where the director requires the installation of an interceptor by a user who is neither an SIU nor a CIU, the user shall also be required to obtain a pollution prevention permit. Typical users required to install an interceptor and obtain a pollution prevention permit include, but are not limited to, restaurants, cafes, lunch counters, cafeterias, bars and clubs; hotels, hospitals, sanitariums, factory or school kitchens, equipment repair shops, service stations, and other establishments where grease, oils, sand, or grit may be introduced into the city’s sanitary sewer system in quantities that can obstruct the sewer or hinder wastewater treatment or private wastewater disposal.
2. All interceptors shall be of a type and capacity approved by the director and shall be so located as to be readily and easily accessible for cleaning and inspection. Interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight and equipped with easily removable covers which, when bolted in place, are gas- and water-tight. All interceptors shall be maintained by the user, at the user’s expense, in continuously efficient operation at all times.
3. Each user shall regularly inspect, clean, and repair interceptors. Records of inspections, cleaning and repairs, and the costs associated with these actions shall be kept for a minimum of three (3) years and be made available for inspection by city personnel upon request. Debris from interceptors shall be disposed of through a licensed waste hauler. Waste disposal records, including receipts, shall be kept for a minimum of three (3) years and be made available for inspection by city personnel upon request.
4. All interceptors shall comply with the following standards:
a. Plans shall be submitted to and approval obtained from the director prior to the installation of any interceptor.
b. All drains from kitchen areas including pre-wash shall be connected to an interceptor. Toilets, lavatories and other sanitary fixtures shall not be connected to any interceptor.
c. All fixtures discharging into an interceptor shall be individually trapped and vented in a manner approved by the director.
d. Each interceptor shall be so installed and connected that it shall be at all times easily accessible for inspection, cleaning, and removal of the intercepted material.
e. Interceptors shall be maintained in efficient operating condition by periodic removal of the accumulated materials. No such collected material shall be introduced into any drainage piping, public or private, or discharged to the city’s sanitary sewer system.
f. Each interceptor shall be constructed of durable materials satisfactory to the director and shall have a full-size gas-tight cover which can easily and readily be removed.
g. Interceptors required by this chapter shall not be installed until the type and/or model has been subjected to, and has fully complied with, tests acceptable to the director. Where existing conditions are found acceptable as determined by the director, such facilities as presently exist will be allowed to remain in use. Whenever it shall come to the attention of the director that any interceptor is no longer acceptable or does not comply with the provisions of this section, the director shall suspend or revoke such approval and require corrective measures.
