(a) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid, or gas.

(b) 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 but not limited to cyanides in excess of two 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.

(d) 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, 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 Director 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 opinion as to the acceptability of these wastes, the Director will give consideration to such factors as to 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 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 150 degrees Fahrenheit (65 degrees Celsius).

(b) Any water or waste containing fats, 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 degrees Fahrenheit (zero and 65 degrees Celsius).

(d) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not.

(e) 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 Director 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 Director as necessary, after treatment of the composite sewage, to meet the requirements of the State, Federal, or other public agencies of jurisdiction for such discharge to the receiving waters.

(g) Any radioactive wastes or isotopes of such half-life of concentration as may exceed limits established by the Director in compliance with applicable State or Federal regulations.

(h) Any waters or wastes having a pH in excess of 9.5.

(i) Materials which exert or cause:

(i) 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 and sodium sulfate).

(ii) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).

(iii) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.

(iv) Unusual volume of flow or concentration of wastes constituting “slugs” as defined in MCC 13.15.010.

(j) 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.

(5) When 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 subsection (4) of this section, or which in the judgment of the 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 Director 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 subsection (10) of this section.

If the 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 Director, 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 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 Director, 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 waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.

(8) When required by the Director, the owner of any property served 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 Director. 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.

(9) 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 40 CFR 136, 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 will be obtained from 24-hour composites of all outfalls whereas pHs will be determined from periodic grab samples.

(10) 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. (Ord. 428, § 5; amended by Ord. 885, § 1, May 5, 1981; Ord. 1335, § 1, December 3, 2013. Code 1983 § 72.140.)

(2) While performing the necessary work on private properties referred to in subsection (1) of this section, the Director or duly authorized employees of the City shall observe all safety rules applicable to the premises established by the company and the company shall be held harmless for injury or death to the City employees and the City shall indemnify the company against loss or damage to its property by City employees and 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 MCC 13.15.040(8).

(3) The Director, and other duly authorized employees of the City, bearing proper identification, shall be permitted to enter upon any private property for the purposes of inspection, testing, measurement, sampling, repair and/or maintenance of any building sewer, sewer cleanout, sampling station or other parts of the sewerage works. Except in emergencies, such entry upon private property shall be preceded by notice to the property owner and shall be made at reasonable times and in such manner as to cause a minimum of inconvenience or damage to the private property owner. (Ord. 428, § 7; amended by Ord. 885, § 1, May 5, 1981; Ord. 941, § 1, Feb. 7, 1984. Code 1983 § 72.160.)

13.15.070 Sewer service charges and fees.

(1) Sewer Service Charges. All sewer users shall pay a monthly sewer service charge. Such charge shall be set by resolution of the City Council.

(2) Connection Fees. The owner of any property to be served by any building sewer shall pay, upon application for such connection, a fee therefor. The schedule of such fees shall be set by resolution of the City Council.

(3) Collection of Sewer Service Charges. All collections of sewer service charges under this section shall be made by and through the Common Council and shall be computed monthly at the same time as the water bills and be added thereto and be payable on the dates and at the place as provided for the payment of water bills. Where the first water bill after the sewer service charge becomes effective is computed as of a date of less than one month after said sewer service charge has become effective, said sewer service charge shall be proportioned according to the portion of the month for which it is effective.

(4) Delinquent Accounts.

(a) All sewer service charges shall be paid by the operator or occupant of business or dwelling and may be deducted from any deposits held in the Electric or Water Department of the City, and said ledger record shall be made accessible for inspection by anyone interested in ascertaining the amount of such charges against the property.

(b) All charges or fees for sewer service shall be chargeable to the premises to which the service is provided. Whenever any account for sewer service to any building or premises shall become due and payable by reason of the occupant in said building or upon said premises vacating the same, or by reason of the discontinuance of service by the City for nonpayment of account, water service shall not be furnished to said building or at said premises until all outstanding obligations or charges are paid. Water service may be discontinued to water users having delinquent sewer service accounts when the Common Council deems such action necessary to enforce collection of such delinquent accounts. Otherwise, the manner and method of collection and payment of sewer service charges or accounts shall be the same as provided by the Common Council for the collection and payment of accounts for water service. (Ord. 428, § 8; amended by Ord. 885, § 1, May 5, 1981; Ord. 1336, § 1, December 3, 2013. Code 1983 § 72.170.)

13.15.080 Special sewer improvement account.

All funds derived from the collection of service shall be credited to a special account and shall be expended only for the purposes designated below:

(1) For the construction of a sewage treatment plant or plants;

(2) For the construction of lateral sewers, intercepting sewers, sewage pumping plants or other sewage facilities;

(3) For the operation, maintenance, repair, replacement or reconstruction of any of the above sewage facilities. (Ord. 885, § 1, May 5, 1981. Code 1983 § 72.180.)

13.15.090 Appeal of inequitable rates.

Whenever any sewer user shall in writing protest the application of any charge provided for herein on the grounds that the rate computation thereof is inequitable or unreasonable, the Common Council shall make or cause to be made an investigation of such protest and determine the reasonableness of such charge, and if the Council shall find such unreasonable in any given case, it shall fix a fair and reasonable rate and charge to be based on the use made of the sewers and sewage facilities by the protesting sewer user. (Ord. 885, § 1, May 5, 1981. Code 1983 § 72.190.)

13.15.100 Repair and replacement.

(1) Any building sewer, whether upon private property or within the street or other public right-of-way, found to be damaged, obstructed or permitting infiltration of ground or surface waters shall be repaired or replaced when so ordered by the Director. All repair work must be inspected by the City. The cost of such repair or replacement for that portion of the building sewer which is on private property shall be borne by the owner of the property served by the building sewer. Costs of repair within public rights-of-way shall be borne by the City.

(2) Property owners notified to repair or replace building sewers shall do so within the time specified in the notice. If property owners fail to make repairs the City may make or cause to be made the repairs, in which case the costs of such repair work shall become a lien against the property which may be satisfied as set forth in MCC 13.15.110. Such lien would accrue interest.

(3) The City shall have the power to repair or replace building sewers found to be defective in any case where the property owner has failed to make the ordered repairs in a timely manner. Such repairs or replacement shall be made at property owner’s expense.

(4) For violations of this chapter due to failure to obey an order of the Director to repair or replace, and in addition to the remedies provided in MCC 13.15.120, the City may impose a penalty in an amount not to exceed $100.00 for each monthly billing period during which such violation continues.

(5) Appeal from enforcement of these regulations imposed by the Director of Public Works under this chapter may be made to the City Manager. (Ord. 885, § 1, May 5, 1981; amended by Ord. 941, § 1, Feb. 7, 1984. Code 1983 § 72.200.)

13.15.110 Lien against property.

Any charge or fee required by this chapter for the construction, replacement or repair of any building connection which shall remain unpaid shall be a lien against the property served by such connection and shall be docketed, shall draw interest, and shall be foreclosed in the manner of any City lien. (Ord. 445, § 1; amended by Ord. 885, § 1, May 5, 1981. Code 1983 § 72.210.)
