(A)   No person shall discharge, or cause to be discharged, any storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any public sanitary sewer.
   (B)   Storm water and all other unpolluted drainage shall be discharged to storm sewers or to a natural outlet approved by the Superintendent.  Industrial cooling water or unpolluted process waters may be discharged upon approval of the Superintendent, to a storm water sewer or natural outlet.
   (C)   No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
      (1)   Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas;
      (2)   Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant;
      (3)   Any waters or wastes having a pH lower than 5.5 or higher than 9.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewerage works; or
      (4)   Solid or viscous substances in quantities of a size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers and the like, either whole or ground by garbage grinders.
   (D)   No person shall discharge or cause to be discharged to a public sanitary sewer the following described substances, materials, waters or wastes if it appears likely in the opinion of the Superintendent that the waters or wastes, singly or by interaction with other wastes, can harm either the sewers, sewage treatment process, or equipment; can cause an adverse effect on the receiving stream in violation of Chapter 3 of the Water Pollution Rules and Regulations adopted by the Illinois Pollution Control Board pursuant to the Illinois Environmental Protection Act, 415 ILCS 5/13 or in violation of the effluent limitations of the NPDES permit; or can otherwise endanger the life, limb, public property or constitute a nuisance. In forming this opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of the waters or wastes in relation to flows and velocities in the sewers, materials or construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatablity of wastes in the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited are:
      (1)   Any liquid or vapor having a temperature higher than 150°F (65°C);
      (2)   Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of 100 mg/l) or containing substances which may solidify or become viscous at temperatures between 32°F and 150°F (0°C and 65°C);
      (3)   Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower (0.76 ph metric) or greater shall be subject to the review and approval of the Superintendent;
      (4)   Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions whether neutralized or not;
      (5)   Any industrial wastes containing substances exceeding the following maximum concentrations of pollutants:
Maximum Concentration (mg/l)
Maximum Concentration (mg/l)
Maximum Concentration (mg/l)
Maximum Concentration (mg/l)
5-day BOD
Total suspended solids
Total dissolved solids
Chemical oxygen demand
Oil (Hexane soluble)
Chromium (Hexavalent)
Chromium (total)
(1) IPCB Regulations, Chapter 3, § 703(a).
(2)IPCB Regulations, Chapter 3, § 702(a).
      (6)   Any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the village in compliance with applicable state or federal regulations;
      (7)   Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg at any time except as permitted by the village in compliance with applicable state and federal regulations;
      (8)   Any cyanide in excess of 0.025 mg/l at any time except as permitted by the village in compliance with applicable state and federal regulations;
      (9)   Materials which exert or cause:
         (a)   Unusual concentrations or inert suspended solids (such as but not limited to Fuller’s earth, lime slurries, and lime residues) or of dissolved solids (such as but not limited to sodium chloride and sodium sulfate);
         (b)   Excessive discoloration (such as but not limited to dye wastes and vegetable tanning solutions);
         (c)   Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works; and
         (d)   Unusual volume of flow or concentrations of wastes constituting “slugs” as defined herein.
      (10)   Waters or wastes containing substances which are not amendable to treatment or reduction by the sewage treatment processes employed, or are amendable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to receiving waters.
   (E)   If any waters or wastes are discharged, or are proposed to be discharged to the public sanitary sewer, which waters contain the substances or possess the characteristics enumerated in division (D) herein, and/or which are in violation of the standards for pretreatment provided in current EPA rules and regulations as amended, and which in the judgment of the village may have a deleterious effect upon the sewage works, processes, equipment or receiving water, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may reject the wastes; require pretreatment to an acceptable condition for discharge to the public sanitary sewer; require control over the quantities and rates of discharge; and/or require payment to cover the added costs of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of division (K) of this section.  If the Superintendent permits the pretreatment or equalization of wastewater flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable codes, ordinances and laws.
   (F)   Grease, oil and 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 the 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.
   (G)   Where pretreatment or flow-equalizing facilities are provided, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
   (H)   Each industry shall be required to install a control manhole and, when required by the village, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with the necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. This manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the village. 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.
   (I)   The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests and analyses of waters and wastes to demonstrate compliance with this chapter and any special conditions for discharge established by the village or regulatory agencies having jurisdiction over the discharge. The number, type and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the village, but no less than once per year the industry must supply a complete analysis of the constituents of the wastewater discharge to assure that compliance with the federal, state and local standards are being met. The owner shall report the results of measurements and laboratory analyses to the village at such times and in a manner as prescribed by the village. The owner shall bear the expense of all measurements, analyses and reporting required by the village. At such times as deemed necessary, the village reserves the right to take measurements and samples for analysis.
   (J)   All measurements, tests and analyses 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 Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, and “USEPA Guidelines Establishing Test Procedures for Analysis of Pollutants” pursuant to 40 C.F.R. pt. 136, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control 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 to life, limb and property.  (The particular analyses involved will determine whether a 24-hour composite sample or whether a grab sample or samples should be taken.  Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composite samples, whereas pHs are determined from periodic grab samples.)
   (K)   No statement contained in this section shall be construed as preventing any special agreement or arrangement between the village and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the village for treatment, subject to payment therefor by the industrial concern; provided, the payments are in accordance with the sewer user service charge ordinance of the village, as set forth in Chapter 51 of this title.
