12.0304 Use of Public Sewers
1) 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 sanitary sewer.
2) 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 Superintendent. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Superintendent, to a storm sewer, combined sewer, or natural outlet.
3) No person shall discharge or cause to be discharged any of the following described water or wastes to any public sewers:
a) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas;
b) Any water or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantities, 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, including
but not limited to cyanides in excess of two (2) mg/l as CN in the wastes as discharged to the public sewer;
c) 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; and
d) Solids 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, etc. Either whole or ground by garbage grinders.
4) 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 street, or can otherwise endanger life, limb, public property, or constitute a nuisance.
In forming his/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, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
a) Any liquid or vapor having a temperature higher than one hundred fifty (150) degrees F (65 degrees C).
b) Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of one hundred (100) mg/l
or containing substances which may solidify or become viscous at temperatures between thirty-two (32) and one
hundred fifty (150) degrees F (0 and 65 degrees C).
c) 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) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the
d) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized
e) Any waters or wastes containing iron, chromium, copper, zinc, and similar objectional or toxic substances; or wastes
exerting and 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.
f) 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 the state, federal, or other public agencies or jurisdiction for such discharge to the receiving waters.
g) 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.
h) Any water or wastes having a ph in excess of 9.5.
i) Materials which exert or cause:
1) unusual concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and
line residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate);
2) excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
3) unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant
load on the sewage treatment works; and
4) unusual volume of flow or concentration of wastes constituting “slugs” as defined herein.
j) 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 sewage treatment plant effluent
cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
5) If any water or wastes are discharged, or are proposed to be discharged to the public sewers, which water contains the substances or possess the characteristics enumerated in #4 of this article, 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 or constitute a public nuisance, the Superintendent may:
a) reject the wastes,
b) require pretreatment to an acceptable condition for discharge to the public sewers,
c) require control over the quantities and rates of discharge, and/or
d) 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 this ordinance
If the Superintendent permits the pretreatment or equalization of waste flows, the design 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.
6) 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.
7) Where preliminary treatment or flow-equalizing facilities are provided for any water or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his/her expense.
8) When required by the Superintendent, the owner of any property servied 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 Superintendent. The manhole shall be installed by the owner at his/her expense and shall be maintained by him/her so as to be safe and accessible at all times.
9) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this ordinance 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 twenty-four (24) hour composite of all outfalls of a premise 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.)
10) No statement contained in this article shall be construed as preventing any special agreement or arrangement between the city and industrial concern whereby an industrial waste of unusual strength of character may be accepted by the city for treatment, subject to payment therefore, by the industrial concern.
