(A) No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, including interior and exterior foundation drains, uncontaminated cooling water or unpolluted industrial 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 Superintendent. Industrial cooling water or unpolluted process water may be discharged, on approval of the Superintendent, to a storm sewer, combined sewer or natural outlet. The contributor of any identifiable discharge of polluted water to the sanitary sewer system shall be held responsible for reimbursing the municipality for such costs. The costs shall be determined by the Superintendent with the approval of the governing body.
(Prior Code, § 3-239) Penalty, see § 53.999
(A) 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 waste treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the wastewater treatment plant;
(3) Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works;
(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 sewage 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 and the like, either whole or ground by garbage grinders; and/or
(5) Any waters or wastes having:
(a) A five-day BOD greater than 300 parts per million by weight;
(b) Containing more than 350 parts per million by weight of suspended solids;
(c) An average daily flow greater than 2% of the average sewage flow of the municipality; or
(d) A chlorine requirement greater than demanded by normal sewage as evaluated by the municipality’s consulting engineer shall be subject to the review of the Superintendent.
(B) Where necessary in the opinion of the Superintendent, the owner shall provide, at his or her expense, such preliminary treatment as may be necessary to:
(1) Reduce the biochemical oxygen demand to 300 parts per million by weight;
(2) Reduce the suspended solids to 350 parts per million by weight;
(3) Control the quantities and rates of discharge of such waters or wastes; or
(4) Reduce the chlorine requirement to conform with normal sewage.
(C) Plans, specifications and other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
(Prior Code, § 3-240) Penalty, see § 53.999
(A) 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 Superintendent that such wastes can harm either the sewers, sewage 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 his or her opinion as to the acceptability of these wastes, the Superintendent 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 sewage treatment process, capacity of the sewage treatment plant and other pertinent factors.
(B) The substances prohibited are:
(1) Any liquid or vapor having a temperature higher than 150°F (65°C);
(2) Any water or waste containing fats, wax, grease 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° and 150°F (0° and 65°C);
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor three-fourths’ horsepower (0.76 hp 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 water or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials;
(6) Any waters or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of state, federal or other public agencies of jurisdiction for such discharge to the receiving waters;
(7) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations;
(8) Any waters of wastes having a pH in excess of 9.5;
(9) Materials which exert or cause:
(a) Unusual concentrations of 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 or 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; or
(d) Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein.
(10) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(Prior Code, § 3-241) Penalty, see § 53.999
(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 § 53.077, and which, in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life to constitute a public nuisance, the Superintendent 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 cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 53.082.
(B) If the Superintendent 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 Superintendent, and subject to the requirements of all applicable codes, ordinances and laws.
(Prior Code, § 3-242)
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 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. In the maintaining of these interceptors, the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Superintendent. Any removal and hauling of the collected materials not performed by the owner’s personnel must be performed by currently licensed waste disposal firms.
