(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 Village Administrator. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Village Administrator, to a storm sewer, combined 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 wastewater treatment processes, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the wastewater treatment plant, including, but not limited to, cyanides in excess of two (2) mg/l as CN in the wastes as discharged to the public sewer. All discharges containing toxic materials shall be regulated as provided in subsection (c) and (d) hereof.
(3) Any waters or wastes having a pH lower than 6.0, or having any other corrosive property capable of causing damage or hazard to structure, equipment and personnel of the wastewater facilities.
(4) 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 wastewater facilities 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, etc. either whole or ground by garbage grinders.
(d) No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Village Administrator, that such wastes can harm either the sewers, wastewater treatment process, or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming its opinion as to the acceptability of these wastes, the Village Administrator will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the wastewater treatment process, capacity of the wastewater treatment plant, degree of treatability of wastes in the wastewater treatment plant, and other pertinent factors. The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than one hundred fifty degrees (150o) F.
(2) Any water or waste containing fats, wax, grease, oils, or similar substances which may solidify or become viscous at temperatures between thirty-two (32) and one hundred fifty degrees (150o) F.
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) hp or greater shall be subject to the review and approval of the Village Administrator.
(4) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Village Administrator in compliance with applicable State or Federal regulations.
(5) Any waters or wastes having a pH in excess of 9.0.
(e) Any person whose operations entail the discharge of water or wastes containing toxic or poisonous substances shall file with the Village Administrator a written statement setting forth the nature of the operation contemplated or presently carried on, the amount of water required to be used and its source, the proposed point of discharge of said wastes into the sewer system of the Village, the estimated amount so to be discharged, and a fair statement setting forth the expected bacterial, physical, chemical, and other known characteristics of said wastes. Within 30 days of receipt of such statement it shall be the duty of the Village Administrator to make an order stating such minimum restrictions as in the judgment of the Village Administrator may be necessary to guard adequately against unlawful uses of the Village sewage system.
(f) 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 Section 933.04, and which in the judgement of the Village Administrator may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Village Administrator 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 and treating the wastes not covered by existing taxes or sewer charges under the provisions of subsection (j) of this section.
If the Village Administrator 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 Administrator and subject to the requirements of all applicable codes, ordinances, and laws.
(g) Grease, oil and sand interceptors shall be provided when, in the opinion of the Village Administrator, 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 Village Administrator and shall be located as to be readily and easily accessible for cleaning and inspection.
(h) 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 expense.
(i) When required by the Village Administrator, 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 accessibly and safely located, and shall be constructed in accordance with plans approved by the Village Administrator. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
(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 shall be determined 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 wastewater facilities and to determine the existence of hazards to life, limb, and property.
(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 therefore by the industrial concern.
