§ 18-162 PRELIMINARY TREATMENT FACILITIES.
   (A)   To equalize flows and to avoid temporary overloads, any person who discharges into the city’s sanitary sewer system waste having a volume in excess of 50,000 gallons in any 24-hour period may be required by the city to construct suitable storage tanks or equivalent devices according to city specifications relating to type of construction, storage capacity and similar matters. The control of the volume of discharges of waste shall be by a waterworks type rate controller or equivalent device, the setting and operations of which shall be subject to the reasonable direction of the Administrator.
   (B)   Whenever the total volume of wastes to be discharged by any person in any one day has considerable variation in pollutional value, such person may be required to construct holding or storage tanks in order to control the discharge of wastes over a 24-hour period. Such tanks shall be in duplicate and be so equipped as to mix the waste so thoroughly that its quality will be uniform when discharged into the sanitary sewer system.
   (C)   Grease, oil and sand or mud interceptors shall be provided when, in the opinion of the Administrator, they are necessary for the proper handling and control of liquid wastes containing grease, oil, sand or mud in excessive amounts. Such interceptors shall not be required for private living quarters or dwelling units, but may be required for industrial or commercial establishments, public eating places, hotels, hospitals, automobile service stations, car washes or other institutions. Such interceptors shall be located as to be readily accessible for cleaning and inspection and shall be maintained by the owner at his or her expense in continuously efficient operation at all times.
   (D)   Plans, specifications and other pertinent information relating to proposed preliminary treatment or handling facilities, including the construction of storage tanks, inspection or control manholes, and controlling devices as required under this section, shall be submitted to the Administrator for approval, and no construction of such facilities shall be commenced until such approval is obtained in writing.
   (E)   Where preliminary treatment or handling facilities are provided for any purpose, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her own expense.
