(A) Storm water 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 village. Industrial cooling water or unpolluted process waters may be discharged on approval of the village to a storm sewer, combined sewer, or natural outlet.
(B) Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following materials to any sewer:
(1) Any liquid or vapor having a temperature high enough to create damaging or adverse effects on the treatment process or to prevent compliance with IEPA regulations;
(2) Any water or waste which may contain more than 100 parts per million by weight of fat, oil, grease, or hexane extractable material;
(3) Gasoline, benzene, naphtha, fuel oil, or other combustible, flammable, or explosive liquid, solid, or gas of whatsoever kind or nature;
(4) Any garbage that has not been properly shredded;
(5) Solid or viscous substances in quantities or of such 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, unground 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;
(6) Any waters or wastes having a pH lower than five and five-tenths or higher than nine or having any other corrosive property capable of causing damage or hazard to sewers, structures, equipment, and personnel of the sewage works;
(7) Any waters or wastes containing any toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process or as would constitute a hazard to humans or animals, or could create any hazard in the receiving waters of the sewage treatment plant;
(8) Any waters or wastes containing BOD or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, except as may be permitted by specific, written agreement with the District, which agreement may provide for special charges, payments, or provisions of treating and testing equipment;
(9) Any noxious or malodorous gas or substance capable of creating a public nuisance;
(10) Any waters or wastes containing radioactive material or radioisotopes (giving off radiant energy in the form of alpha, beta, or gamma rays) in sufficient quantity to injure or interfere with any sewage treatment process, constituting a hazard to humans or animals, or creating any hazard in the receiving waters of the sewage treatment plant;
(11) Any amount of the following constituents exceeding that listed below:
Material | Amount |
Material | Amount |
Ammonia nitrogen, total | 50 mg/l |
Arsenic | 0.01 mg/l |
Barium | 1 mg/l |
Boron | 1 mg/l |

Manganese | 0.09 mg/l |
Mercury | 0.0005 mg/l |
Nickel | 1 mg/l |
Phenols | 0.3 mg/l |
Phosphorus | 0.05 mg/l |
Selenium | 1 mg/l |
Silver | 0.005 mg/l |
Sulfate | 250 mg/l |
Total solids | 1,800 mg/l |
Zinc | 1 mg/l |
(12) (a) 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 this section, and/or which are in violation of the standards for pretreatment provided in 40 C.F.R. 403, June 26, 1978, and any amendments thereto, and which in the judgment of the village may have a deleterious effect upon any portion of the sewer system, or which otherwise create a hazard to life or constitute a public nuisance, the village may:
1. Reject the wastes;
2. Require pretreatment to an acceptable condition for discharge to the public sewers;
3. Require control over the quantities and rates of discharge; and/or
4. Require payment to cover the added costs of handling the wastes not covered by existing taxes or sewer charges, under the provisions of § 50.03.
(b) If the village permits 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 village, and subject to the requirements of all applicable codes, ordinances, and laws.
(13) No provision of this section shall be construed to provide lesser discharge standards than are presently or may hereafter be imposed and required by USEPA or IEPA.
(C) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Public Works Director 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 Public Works Director, and shall be located as to be readily and easily accessible for cleaning and inspection.
(D) 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.
(E) Each industry shall be required to install a control manhole, and when required by the Public Works Director, 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 Public Works Director. 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.
(F) (1) The owner of any property serviced by a building sewer carrying industrial wastes shall provide laboratory measurements, tests, and analyses of water and wastes to illustrate compliance with this chapter and any special conditions for discharge established by any regulatory agencies having jurisdiction over the discharge.
(2) The number, type, and frequency of laboratory analyses to be performed by the owner shall be as stipulated by the District 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 District at such times and in such manner as prescribed by the District. The owner shall bear the expense of all measurements, analyses, and reporting required by the District.
(G) 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 shall be determined at the control manhole provided, or upon suitable samples taken at said 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 of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pH’s are determined from periodic grab samples.
