13.65.020 Unlawful wastes.

Except as hereinafter provided, no person, partnership or corporation shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:

(1) Any liquid or vapor having a temperature higher than 150 degrees Fahrenheit.

(2) Any water or waste which may contain more than 100 parts per million, by weight, of fat, oil or grease.

(3) Any gasoline, benzine, naphtha, fuel oil, lube oil or other flammable or explosive liquid, solid or gas.

(4) Any garbage that has not been properly shredded.

(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure or any other solid or viscous substance capable of causing obstructions to the flow in sewers or other interference with the proper operation of the sewage works.

(6) Any waters or wastes having a pH lower than 5.5 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the Utility.

(7) Any waters or wastes containing toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewage treatment plant.

(8) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant.

(9) Any noxious or malodorous gas or substance capable of creating a public nuisance. [Ord. 76 § 13.02, 12-6-2004 (Res. 2004-467)].

13.65.030 Interceptors.

Grease, oil and sand interceptors shall be provided when, in the opinion of the manager, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand and other harmful ingredients. Such interceptors shall be of a type and capacity approved by the manager and shall be so located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight and equipped with easily removable covers, which when bolted in place shall be gas-tight and water-tight. [Ord. 76 § 13.03, 12-6-2004 (Res. 2004-467)].

13.65.040 Interceptors – Maintenance.

Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, for continuously efficient operation at all times. A record of such maintenance shall be furnished to the manager upon request. [Ord. 76 § 13.04, 12-6-2004 (Res. 2004-467)].

13.65.050 Forbidden wastes – Pre-treatment and approval.

The admission into the public sewer of any waters or wastes having:

(1) A five-day B.O.D. greater than 300 parts per million weight; or

(2) Containing more than 350 parts per million by weight of suspended solids; or

(3) Containing any quantity of substances having the characteristics described in TTC 13.65.020; or

(4) Having an average daily sewage flow of greater than two percent of the average daily sewage flow of the Utility;

shall be subject to the review and approval of the manager. Where necessary in the opinion of the manager, the owner shall provide, at his expense, such preliminary treatment as may be necessary to:

(a) Reduce the B.O.D. to 300 parts per million by weight, and the suspended solids to 350 parts per million by weight; or

(b) Reduce objectionable characteristics or constituents to within the maximum limits provided for in TTC 13.65.020; or

(c) Control the quantities and rates of discharge of such waters or wastes.

Plans, specifications and other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the manager and the appropriate Federal and/or State agencies when required by law, and no construction of such facilities shall be commenced until such approvals are obtained in writing. Any expenses incurred by the Utility in reviewing such plans, specifications and information shall be paid by the property owner or his or her representative before issuance of approval by the Utility. [Ord. 76 § 13.05, 12-6-2004 (Res. 2004-467)].

13.65.060 Preliminary treatment facilities – Maintenance.

Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense. [Ord. 76 § 13.06, 12-6-2004 (Res. 2004-467)].

13.65.070 Industrial wastes – Control manhole.

When required by the manager, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement for the wastes. Such manhole, when required, shall be accessible and safely located, and shall be constructed in accordance with plans approved by the manager. The manhole shall be installed by the owner at his or her expense and shall be maintained by the owner so as to be safe and accessible at all times. [Ord. 76 § 13.07, 12-6-2004 (Res. 2004-467)].

13.65.080 Tests of wastes – Location of sampling.

All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in TTC 13.65.020 and 13.65.050 shall be determined in accordance with “Standard Methods for the Examination of Water and Sewage,” and shall be determined at the control manhole provided for in TTC 13.65.070, 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. [Ord. 76 § 13.08, 12-6-2004 (Res. 2004-467)].

13.65.090 Special agreements.

Nothing in this chapter shall be construed as preventing any special agreement or arrangement between the Utility and the manufacturing of any industrial waste whereby industrial waste of unusual strength or character may be accepted by the Utility for treatment, subject to payment therefor by that manufacturer. [Ord. 76 § 13.09, 12-6-2004 (Res. 2004-467)].
