(A) Grease, oil, sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent, and shall be located as to be readily and easily accessible for cleaning and inspection.
(B) Grease and oil 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, shall be gas-tight and water-tight. Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at the owner’s expense, in continuously efficient operation at all times.
(C) Where preliminary treatment or flow-equalizing facilities are provided, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(Prior Code, § 18-9-5)
(A) Where required by the city, the owner of a property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with approved plans. The plans detail the location and type of manhole, meter, flume and other appurtenances deemed necessary by the city shall be submitted for review to the city. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.
(B) The preferred location of the control manhole shall be outside of any building structure so as to be more accessible. If locks are place on the entrance to the manhole structure, the owner shall provide the city with a key.
(1) Where required by the city, other users who discharge or could potentially discharge greater than normal domestic strength wastewater to the public sewer shall provide a monitoring location, sampling equipment or other appurtenances that are deemed necessary by the city to characterize the quantity and strength of the wastewater discharged to the public sewers. The required flow monitoring equipment and other appurtenances specified by the city shall be installed by the owner at his or her expense, and shall be maintained by the owner so as to be safe and accessible at all times.
(2) A maintenance schedule of flow monitoring and sampling equipment must be accepted by the city. All maintenance and equipment repair shall be performed within a reasonable time as determined by the city. Failure to perform maintenance within a reasonable time shall be subject to the same forfeiture and procedural provisions as applied to violations under the sewer use ordinance. Prior to completion of satisfactory repairs, and for any preceding period during which the city determines there existed a malfunction, error or bias in the metering and sampling, the volume and strength of the wastewater for that period of discharge shall be based on historical data and a reasonable engineering estimate of flow and strength, taking into account materials and known production variations and the like. All such factors shall be determined by the city in consultation with the discharger. If prolonged periods of breakdown are anticipated, approved interim measuring and sampling needs shall be provided, and used to determine the volume and strength of wastewater.
(C) Following approval and installation of permanent or temporary metering or sampling equipment, such equipment shall not be removed without the consent of the city.
(Prior Code, § 18-9-6)
(A) The owner of any property serviced by a building sewer carrying industrial wastes, or other users who discharge or could potentially discharge greater than normal domestic strength wastewater to the public sewer shall provide, where required by the city, laboratory measurements, tests and analysis of waters and wastes to illustrate compliance with this chapter and any special conditions for discharge established by the city or regulatory agencies having jurisdiction over the discharge.
(B) The number, type and frequency of laboratory analysis to be performed by the owner shall be as stipulated by the city or regulatory agency, and shall be such that the wastewater can be adequately characterized so that fair and equitable user charges may be accessed to the owner and to assure that compliance with the federal, state and local standards are being met. The owner shall report the results of measurements and samples for analysis by an outside laboratory service.
(C) All measurements, tests and analysis of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of IEPA Division of Laboratories Manual of Laboratory Methods, and shall be determined at the monitoring manhole or sampling location as specified in this chapter or other approved location. In the event that no special manhole has been required, the meter manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards of life, limb and property. The particular analysis involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab samples or samples should be taken. Normally, but not always, BOD suspended solids and ammonia nitrogen analysis are obtained from 24-hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
(Prior Code, § 18-9-7)
No person in the business of gathering and disposing of septic tank sludge or holding tank sewage shall transfer such material into any portion of the city treatment works.
(Prior Code, § 18-9-8) Penalty, see § 52.999
PRIVATE SEWAGE DISPOSAL
Where a public sanitary sewer is not available under the provisions of § 52.004, the building sewer shall be connected to a private sewage disposal system complying with the provisions of this subchapter.
(Prior Code, § 18-10-1)
Before commencement of construction of a private sewage disposal system the owner shall first obtain a written permit signed by the city. The application for such a permit shall contain the name and address of the person or persons intended to have responsibility of the work and a written description of the system, explanation of flows and loading to the private system and any plans, specifications and other information necessary to explain the proposed system and discharge location or other information as deemed necessary by the city. A permit and inspection fee of $25 shall be paid to the city at the time the application is filed.
(Prior Code, § 18-10-2)
