Chapter 13.36 — OPERATION

A.

Except as otherwise provided by this section, no person shall place, deposit or discharge, directly or indirectly, into any public sewer of this city or into any house sewer connection therewith in the city, or on or upon any street, alley or public place or on or upon any private property or any other place in the city in such manner that it will be permitted to run into any such public sewer or house sewer, any of the following substances:

Any oil, petroleum, naphtha, liquid asphaltum or or petroleum product, or any fatty matter, rags, sand, earth or stone dust;

Dead animals, fish, fruit or vegetable matter in any form except garbage deposited into the sanitary sewer system by means of garbage grinders as provided in this chapter;

Any refuse or industrial liquid waste other than domestic sewage that will not readily disintegrate in the sewage treatment plant or that will cause or tend to cause obstructions in the sewer system or the sewage treatment plant or interfere or tend to interfere with the efficient and successful operation of the system of the plant, or cause a potential hazard or objectionable odor;

Any chemicals or waste destructive to masonry;

Grease except in quantities commonly contained in domestic sewage;

Any effluent of a temperature exceeding one hundred forty degrees Fahrenheit;

Any radioactive waste except where special permit has been granted by the city engineer and in type and amounts as specified from time to time by the city engineer. Permission to discharge radioactive waste shall be terminated immediately at the discretion of the city engineer if in his/her opinion the discharge constitutes or may constitute a public health hazard;

Any industrial waste including but not limited to mineral salts, molds, or wastes resulting from their manufacture and other products which will tend to sterilize activated sludge, trickling filter slimes, or slime growth on artificial or natural slow sand filters.

B.

Before any person may discharge alkalis, acids or other corrosive or harmful wastes into the public sewer, he/she shall reduce the biochemical oxygen demand and control the pH to the extent which the city engineer finds adequate taking all circumstances into consideration.

C.

Except as provided in subsection D of this section, no person shall make or maintain any connection with any part of the public sewer for the purpose of discharging sewage or waste which contains any of the objectionable substances mentioned in this section.

D.

Whenever any person desires to make or maintain any connection with any part of the public sewer for the purpose of discharging sewage or waste which contains any of the objectionable substances, the person shall apply to the city engineer for a permit for those purposes. The permit shall be issued only when the city engineer is satisfied that an adequate intercepting appliance has been provided to prevent the objectionable substance or substances from entering the public sewer. The permit shall be issued only upon payment to the city engineer of a fee as set by the city council and shall expire one year after the date of its issuance.

The permit shall be revocable whenever it appears to the city engineer that the holder thereof has violated any provision of this chapter or when the intercepting appliance does not prevent the objectionable substance or substances from

entering the public sewer. The permit shall be revoked by registered mail to the permittee at the address set forth in the permit. The permit shall be deemed revoked as of the fifth day after receipt of the notice.

No holder of any permit issued pursuant to this subsection shall fail to maintain the appliance in a satisfactory working condition.

Permits issued under this subsection shall be nontransferable.

Before granting a permit to any applicant to discharge any industrial liquid waste or industrial sewage into the public sewer, the city engineer shall determine either that the waste is one which will not damage or destroy the public sewer or cause an unwarranted increase in the cost of maintenance of the public sewer or retard or inhibit the treatment of the sewage, or is one that can be made acceptable by pretreatment.

E.

The provisions of this section requiring the installation of adequate intercepting appliances and the obtaining of permits shall not apply to any person maintaining a connection with the public sewer upon the eleventh day of April, 1952, until the expiration of sixty days from that date.

(Prior code § 7500.19)

(Ord. No. 3112, § 2, 2-25-20)

A.

Unpolluted waters from refrigeration systems, air conditioning systems or industrial cooling systems may be discharged into a storm drain sewer or a dry well where space and soil conditions permit such installation. Where the discharge into a storm drain or dry well is not feasible, the unpolluted waters from such systems may be discharged into a public sewer where written permission therefor has been granted by the city engineer. Such permission shall be upon such terms and conditions as the city engineer may prescribe, including the amount of water to be discharged into any such sewer, the time of the discharge and any other reasonable regulations imposed by the city engineer in granting the permission.

B.

Waters from swimming pools may be discharged into a storm drain sewer or into a dry well where space and soil conditions permit the installation of the dry well. If such facilities are not available, then water from swimming pools may be discharged into the public sewer; provided, however, that written permission therefor has been first obtained from the city engineer. If a swimming pool is to be partially or wholly drained, then the water shall be discharged into a public sewer only between the hours of nine p.m. and six a.m. of any day. The city engineer in granting permission to drain any pool into the public sewer may impose reasonable conditions, including the amount of water to be drained into the public sewer and the hours therefor.

(Prior code § 7500.21)

A.

Garbage resulting from the preparation of any food or drink prepared and served or proposed to be served on the premises may be ground and discharged into the public sewer upon approval of the city engineer and the director as to the fineness of content determined by an analysis made with United States sieves and based on wet drained weights in accordance with the following:

Not less than forty percent shall pass a No. 8 sieve;

Not less than sixty-five percent shall pass a No. 3 sieve;

Not less than one hundred percent shall pass a one-fourth-inch screen.

B.

The method of discharge permitted under this section shall be by flushing with water directly into a trapped outlet into the house plumbing leading to the public sewer. The city engineer may limit the permissible quantity of garbage to be disposed of through garbage grinders.

(Amended during 1984 codification; prior code § 7500.23)

No person shall open or enter any maintenance access hole in any public sewer to dispose of garbage or other deleterious substances or storm or surface waters or for any other like purpose.

(Ord. No. 3112, § 2, 2-25-20)

Cesspool effluent which does not contain concentrations of industrial liquid wastes, oil, greases, or other deleterious substances may be dumped into certain specific maintenance access holes when permission in writing is secured from the city engineer. No person shall dump cesspool effluent in any maintenance access hole other than those designated by the city engineer, or do so without permission in writing. Such permission may be granted only upon application in writing by a person engaged in the business of disposing of the effluent. The application shall state the street address of each location from which the effluent is to be obtained. The permit shall give the date and location of the maintenance access hole to be used. The city engineer may refuse to grant such permission to any person who fails to comply with the provisions of this chapter.

(Prior code § 7500.37)

(Ord. No. 3112, § 2, 2-25-20)
