(a) No person shall discharge or cause to be discharged any stormwater, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
(b) Stormwater, surface drainage, subsurface drainage, groundwater, roof runoff, cooling water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the City Engineer. No persons shall use any such sewers without first having obtained the consent and permits from the City Engineer.
(1) Industrial cooling water or unpolluted processed waters may be discharged, on approval of the City Engineer, to a storm sewer or natural outlet.
(2) Roof runoff is required to be directed by a downspout or roof drain away from a building by means of underground storm sewer piping. Such storm sewer piping shall be constructed in accordance with standards set by the City Engineer and shall discharge to a storm sewer. In the event that a storm sewer is not readily available, as determined by the City Engineer, to serve storm sewer piping for roof runoff, then such roof runoff may be discharged by underground storm sewer piping to a ditch or stream or to a leaching bed designed and constructed in accordance with standards set by the City Engineer. Splash blocks may only be used when authorized under the provisions of Section 911.19, or for small roof areas such as sheds or garages accessory to existing single family residences when approved by the City Engineer, and no water is allowed to drain onto adjacent property, accumulate in depressions or otherwise become a public hazard or nuisance.
(c) No person shall discharge or cause to be discharged any of the following described waters or wastes into any public sewers:
(1) Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW which exceeds forty degrees Centigrade, 104 degrees Fahrenheit.
(2) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquids, solids or gases which by reason of their nature or quantity are or may be sufficient, either alone or by interaction, to cause fire or explosion or be injurious in any other way to the operation of the POTW. Under no circumstances shall the flashpoint of any discharge be less than 140 degrees Fahrenheit or sixty degrees Centigrade as measured using the closed cup test method specified in 40 CFR 261.21.
(3) Any discharge of petroleum oil, nonbiodegradeable cutting oil or products of mineral oil origin in amounts that can cause interference or pass through; but in no case, water or wastes containing free oils, emulsified oils and grease exceeding an average of 100 parts per million or 833 pounds per million gallons.
(4) 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 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 cyanides.
(5) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower, 0.76 hp metric, or greater shall be subject to the review and approval of the Building Commissioner.
(6) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar plastics, wood paunch, manure, hair and fleshings, entrails, lime slurry, lime residues, chemical residues, paint residues, cannery waste, bulk solids or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with proper operation of the sewage works.
(7) Any waters or wastes containing TSS of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, or any substance which may cause the POTW's effluent or treatment residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process.
(8) Any noxious or malodorous gas or substance capable of creating a public nuisance, or substances causing the release of noxious or poisonous gases after discharge into the public sewer system, or which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.
(9) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions, whether neutralized or not.
(10) Any waters 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 Service Director as authorized in Chapter 917 for such materials, and which might cause the POTW to violate its NPDES and/or other disposal system permits.
(11) Any waters or wastes containing phenols or other taste or odor-producing substances, in such concentrations exceeding limits which may be established by the Service Director 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, and which might cause the POTW to violate its NPDES and/or other disposal system permits.
(12) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Service Director in compliance with applicable State or Federal regulations.
(13) Any waters or wastes having a pH of less than 5.5 or in excess of 9.0. Unless authorized by the Superintendent or Service Director.
(14) Materials which exert or cause:
A. Unusual concentrations of inert TSS 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.
B. Excessive discoloration such as, but not limited to, dye wastes and vegetable tanning solutions.
C. Unusual biochemical oxygen demand, TSS, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
D. Unusual volume of flow or concentration of wastes constituting "slugs" as defined in Section 911.03(81).
(15) 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.
(16) Any water or waste that for a duration of fifteen minutes has a concentration greater than three times that which is specified for TSS and BOD under Section 911.14 and/or which is discharged continuously at a rate exceeding 200 gallons per minute, will be unacceptable.
(d) If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substance or possess the characteristics enumerated in subsection (c) hereof, and which, in the judgment of the Service Director 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 Service Director may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition in accordance with guidelines adopted in the ordinances of this City for discharge into the public sewers;
(3) Require control over quantities and rates of discharge; and/or
(4) Require payment to cover the added cost of handling and treatment of the wastes not covered by existing taxes or sewer charges under the provisions of subsection (i) hereof.
If the Service Director 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 City Engineer and subject to the requirements of all applicable codes, ordinances and laws.
(e) 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 to the approval of the Service Director.
(f) Each person discharging industrial wastes into a public sewer shall construct and maintain one or more control manholes or access points to facilitate observation, measurement and sampling of his wastes, including domestic sewage.
(1) Control manholes or access facilities shall be located and built in a manner acceptable to the Service Director. If measuring devices are to be permanently installed they shall be of a type acceptable to the Service Director.
(2) Control manholes, access facilities and related equipment shall be installed by the person discharging the waste, at his expense, and shall be maintained by him so as to be in safe condition, accessible and in proper operating condition at all times. Plans for the installation of the control manholes or access facilities and related equipment shall be approved by the City Engineer prior to the beginning of construction.
(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 "Standard Methods", as defined in Section 911.03(83), and in accordance with 40 CFR 136 entitled "Guidelines Establishing Test Procedures for Analysis of Pollutants," and shall be determined at the control manhole provided or upon suitable samples taken at such 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 analysis involved will determine whether a twenty-four 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 TSS analyses are obtained from twenty-four hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
Within ninety days following the date for final compliance with applicable categorical pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the treatment facility, any industrial user subject to pretreatment standards and requirements shall submit to the City a report containing the information described in 40 CFR 403.1 (b)(4) - (6).
(h) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor by the industrial concern in proportion to cost and consistent with the user charge system in Chapter 915. No special agreement shall be in violation of any federal or state standards.
(i) No person shall cause the discharge of slugs of water or wastes. Each person producing a discharge into the public sewers in excess of 100,000 gallons in any one day, shall construct and maintain at his own expense, a suitable storage and flow-control facility to insure equalization of discharge over a twenty-four hour period. This facility shall have a capacity of at least fifty percent (50%) of the total normal volume of a twenty-four hour production period, and the outlet to the sewer shall be equipped with a rate-discharge controller or other approved device, the regulation of which shall be directed by the Service Director.

(a) No person shall connect to the public storm sewer system without first obtaining a permit and paying the fee therefor in accordance with Chapter 901.
(b) Wherever public sewers have been constructed within the Municipality and the cost thereof has been wholly or partly paid out of the funds of the City, or financed through the issuance of bonds, and the owners of any property abutting upon or benefiting from such storm sewers make application to tap such storm sewer, no permit shall be issued to make such connection or connections, nor shall such property owner make such connection or connections, unless he shall have first paid into the City treasury or given security for such payment, satisfactory to the fiscal officer of the City, that portion of the cost of such storm sewer which the property was formerly charged in the form of an assessment, but which assessment the City has been unable to collect due to defects in procedure; the failure to obtain an assessment lien; the setting aside of the assessment lien by any court; or the failure to collect such assessment for any reason. Where a portion of the cost of the sewer to which connections are desired to be made has been assessed against such property and a valid assessment lien continues to be imposed thereon for such cost, or where in the case of an invalid assessment, a valid reassessment for such cost has been levied, such permit shall be issued provided the tap-in connection conforms with other regulations of the City.
(c) No permit to construct any improvements upon the property which is subject to subsection (b) hereof shall be issued until such time as the property owner makes the necessary deposit into the City treasury or gives security for such payment satisfactory to the fiscal officer of the City.
(d) Permit and inspection fees for a storm sewer connection, storm sewer and appurtenances shall be as follows:
(1) Each storm sewer connection | $30.00 |
(2) Each 100 lineal feet or fraction thereof storm sewer pipe | 25.00 |
(3) Each catch basin, manhole, yard drain, drive drain, head wall, end wall, junction chamber or similar structure | 10.00 |
(Ord. 92-3. Passed 2-18-92.)
Where required, in the opinion of the Service Director, to modify or eliminate wastes that are harmful to the structures, processes or operation of the sewage disposal works, the person shall provide at his expense such preliminary treatment or processing facilities as may be determined necessary to render his wastes acceptable for admission to the public sewers.
Applicable concentrations shall be based upon average concentrations weighted in proportion to volume of flow, determined during each billing revised by the most practicable method possible.
Review and acceptance of the Service Director shall be obtained prior to the discharge into the public sewers of any waters or wastes having:
(a) A five-day twenty-degree Centigrade BOD greater than 200 ppm;
(b) A TSS content greater than 250 ppm;
(c) An ether-soluble matter, oil and grease content greater than 100 ppm; or
(d) A chlorine requirement greater than fifty ppm, or
(Ord. 84-40. Passed 4-26-84.)
(e) Any substance having a quantity greater than the characteristics described in Section 917.02(f), or any unlisted material with pretreatment limits (state or federal) at a quantity greater than those limits.
(Ord. 90-121. Passed 10-16-90.)
No unauthorized person shall maliciously, willfully or negligently break, damage, destroy, uncover, deface or tamper with any structure, appurtenance or equipment which is part of the sewage disposal system.
No person shall access the sewer system or POTW for any activity including discharge of trucked or hauled septic or industrial wastes except at locations and at times as designated by the Service Director in writing. Any removal of manhole lids, or other access to the sewer system for the purpose of discharging wastes at times and/or locations other than these designated by the Service Director, or without the expressed written permission by the Service Director, shall be considered a violation and shall be subject to enforcement action including fines and penalties allowed under this chapter.
(Ord. 2017-83. Passed 12-19-17.)
(a) The discharger shall allow the Service Director or his duly authorized employees bearing proper credentials and identification to enter upon the premises of the discharger during any reasonable hour for the purposes of inspection, sampling and records examinations and copying to determine compliance with the requirements of this chapter. Where the industry has security measures in force which require proper identification and clearance before entry, the discharger shall make necessary arrangements so that the Service Director or his representative will be permitted entry without delay. The City shall have the right to set up on the discharger's property necessary devices to conduct sampling, inspection, compliance monitoring, metering operations or all of these.
(b) While performing the necessary work on private properties referred to in subsection (a) hereof, the Service Director, Building Commissioner and City Engineer or duly authorized employee of the City shall observe all safety rules applicable to the premises established by the owner, and the owner shall be held harmless for injury or death to the City employees and the City shall indemnify the owner against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions as required in Section 911.12 (g).
(c) The Service Director, Building Commissioner and City Engineer and other duly authorized employees of the City bearing proper credentials and identification shall be permitted to enter all private properties through which the City holds a duly negotiated easement for the purpose of, but not limited to, inspection, observation, measurement, sampling, repair and maintenance of any portion of the sewage works lying within such easement. All entry and subsequent work, if any, on such easement shall be done in full accordance with the terms of the duly negotiated easement pertaining to the private property involved.

(Ord. 84-40. Passed 4-26-84.)
Users connected to public sewers or to a private sewage disposal system will have an opportunity to express complaints and grievances to the Service Director, who shall investigate such complaints and grievances. Where a user requests an adjustment in an extraordinary sewer bill caused by an accident or emergency at the user's property, the Service Director shall conduct an investigation of the accident or emergency, and may make an equitable adjustment to the user's sewer bill where the accident or emergency caused the user to use an extraordinary amount of water and the extraordinary amount of water did not directly enter into the City's public sewers. If the user is dissatisfied with the decision of the Service Director, he or she may appeal the decision of the Service Director to an appeals board consisting of the members of the Environmental Committee of Council, and the Building Commissioner and Finance Director. The Board, upon review of the record of the investigation conducted by the Service Director, may affirm, reverse or modify any decision of the Service Director.
