§ 50.05 USE OF THE PUBLIC SEWERS.
   (A)   No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer.
   (B)   Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the appropriate state agency. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the appropriate state agency, to a storm sewer or natural outlet.
   (C)   Except as hereinafter provided by specific limits, no person shall discharge any of the following described waters or wastes to any public sewers:
      (1)   B.O.D.5 in excess of 200 mg/l;
      (2)   C.O.D. in excess of 450 mg/l;
      (3)   Chlorine demand in excess of 15 mg/l;
      (4)   Color, as from, but not limited to, dyes, inks, vegetable tanning solutions, shall be controlled to prevent light absorbency which would interfere with treatment plant processes or that prevent analytical determinations;
      (5)   Explosive liquid, solid, or gas, gasoline, benzene, naptha, fuel oil, or other flammable material shall not be admitted;
      (6)   Garbage not properly shredded (no particle size greater than one-half inch) shall not be allowed;
      (7)   Grease, oils, wax, fat, whether emulsified or not, in excess of 50 mg/l; or other substances which may solidify or become viscous at temperatures between 32°F and 150°F shall not be admitted to the sanitary sewer;
      (8)   Industrial wastes in concentrations above those listed below, or any other metallic compounds in sufficient quantity to impair the operations of the sewage treatment processes, shall not be allowed to enter sanitary sewers:
Cd
Limitations set forth by appropriate state agencies to comply with federal guidelines for protection of treatment plant and receiving water course, and limitations set forth in the NPDES permit.
Cn6t
Cr
CrTotal
Cu
Fe
Ni
Pb
Phenols
Zn
 
      (9)   Inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate) in unusual concentrations shall not be allowed;
      (10)   Insoluble, solid, or viscous substances such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, tar, feathers, plastics, wood, hair, fleshings, and the like shall not be admitted to sanitary sewers;
      (11)   Noxious or malodorous gas, such as, but not limited to, hydrogen sulfide, sulphur dioxide, or oxides of nitrogen, and oilier substances capable of public nuisance shall not be allowed;
      (12)   pH less than 5.5 or greater than 9.5 shall not be allowed;
      (13)   Radioactive wastes or isotopes of such half-life or concentration which may exceed limits established by applicable state and federal regulations shall not be allowed;
      (14)   Suspended solids in excess of 250 mg/l;
      (15)   Temperature of wastes less than 32°F or greater than 150°F shall not be allowed; and/or
      (16)   Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment to only such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
   (D)   (1)   The village reserves the right to contract with any industrial user to allow said industry to use available excess capacity for discharging wastewaters that exceed the limits of normal strength sewage. If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain the substances or possess the characteristics enumerated in division (C) above, and which in the judgment of the Superintendent or Manager may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the village may:
         (a)   Reject the wastes;
         (b)   Require pretreatment to the level defined as normal strength sewage;
         (c)   Require pretreatment to an acceptable level for discharge to the public sewers;
         (d)   Require control over the quantities and rates of discharge; and/or
         (e)   Require all industrial customers or industries with significant changes in strength or flow to submit prior information to the village and Authority concerning the proposed flows.
      (2)   If the Superintendent and Manager permit the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and Manager and subject to the requirements of all applicable codes, ordinances, and laws.
   (E)   Grease, oil, and sand interceptors shall be provided when, in the judgment of the Superintendent and Manager, 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 dwellings units. All interceptors shall be of a type and capacity approved by the village, and shall be located as to be readily and easily accessible for cleaning and inspection.
   (F)   Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
   (G)   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 such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the Superintendent and Manager. 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.
   (H)   (1)   All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this subchapter shall be determined in accordance with the most recent edition of the Standard Methods for the Examination of Water and Sewage and shall also conform with the Federal Register reprint of October 16, 1973 (40 C.F.R. part 136) which establishes guidelines for testing procedures for analysis of pollutants. All measurements, tests, and analyses shall be determined at the control manhole and upon suitable samples taken at said 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 from the point at which the building sewer is connected.
      (2)   Sampling shall be earned 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 determined whether a 24-hour composite of all outfalls of a premises is appropriate, or whether grab sample or samples should be taken.
   (I)   Industrial cooling water containing such pollutants as insoluble oils or grease or other suspended solids shall be pretreated for removal of the pollutants and then discharged to the storm sewer.
   (J)   Agents of the village, Authority, State Department of Natural Resources, or U.S. Environmental Protection Agency shall have the right to enter all properties for the purpose of inspecting, measuring, sampling, and testing the wastewater discharge.
