[Code 1992, § 13.52(1); amended 3-13-2017 by Ord. No. 17-04]
The City and its Director of Utilities may require each person who discharges or seeks to discharge industrial wastes to a public sewer to prepare and file with the City, at such times as he determines, a report that shall include pertinent data relating to the quantity and characteristics of the wastes discharged to the wastewater collection and treatment facilities. In the case of a new connection, the City may require that this report be prepared prior to making the connection to the public sewers.
[Code 1992, § 13.52(2); amended 3-13-2017 by Ord. No. 17-04]
If any waters or wastes are discharged or are proposed to be discharged to the public sewers which contain substances or possess the characteristics enumerated in Section 78-248 and which, in the judgment of the City, have a deleterious effect upon the wastewater collection and treatment facilities, processes, equipment or receiving waters or which otherwise create a hazard to life, health or constitute a public nuisance, the City, Director of Utilities and staff may:
(1) 
Reject the wastes.
(2) 
Require pretreatment to an acceptable condition for discharge to the public sewers.
(3) 
Require control over the quantities and rates of discharge.
(4) 
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 article.
[Code 1992, § 13.52(3); amended 3-13-2017 by Ord. No. 17-04]
(a) 
Each person discharging industrial wastes into a public sewer shall, at the discretion of the City or its Director of Utilities, construct and maintain one or more control manholes or access points to facilitate observation, measurement and sampling of wastes, including sanitary sewage.
(b) 
Control manholes or access facilities shall be located and built in a manner acceptable to the City. If measuring and/or sampling devices are to be permanently installed, they shall be of a type acceptable to the Director of Utilities.
(c) 
Control manholes, access facilities and related equipment shall be installed by the person discharging the waste, at such person's expense, and shall be maintained by the person so as to be in safe condition, accessible and in proper operating condition at all times. Plans for installation of the control manholes or access facilities and related equipment shall be approved by the City prior to the beginning of construction.
[Code 1992, § 13.52(4); amended 3-13-2017 by Ord. No. 17-04]
The volume of flow used for computing sewer service charges shall be the metered water consumption of the person as shown in the records of meter readings maintained by the water utility, except as noted in Section 78-400.
[Code 1992, § 13.59(5); amended 3-13-2017 by Ord. No. 17-04]
Devices for measuring the volume of waste discharged may be required by the Utility Commission if this volume cannot otherwise be determined from the metered water consumption records. Metering devices for determining the volume of waste shall be installed, owned and maintained by the person discharging the wastewater. Following approval and installation, such meters may not be removed without the written consent of the Utility Commission.
[Code 1992, § 13.52(6); amended 3-13-2017 by Ord. No. 17-04]
(a) 
Industrial wastes discharged into the public sewers shall be subject to periodic inspection and a determination of character and concentration of such wastes. The determination shall be made by the industry as often as may be deemed necessary by the Utility Commission.
(b) 
Samples shall be collected in such a manner as to be representative of the composition of the wastes. The sampling may be accomplished either manually or by the use of mechanical equipment acceptable to the Utility Commission.
(c) 
Installation, operation and maintenance of the sampling facilities shall be the responsibility of the person discharging the waste and shall be subject to the approval of the Utility Commission. Access to sampling locations shall be granted to the Utility Commission at all times. Every care shall be exercised in the collection of samples to ensure their preservation in a state comparable to that at the time the sample was taken.
[Code 1992, § 13.52(7); amended 3-13-2017 by Ord. No. 17-04]
Persons discharging industrial wastes into any public sewer may be required to pretreat such wastes, if the Utility Commission determines pretreatment is necessary to protect the wastewater collection and treatment facilities or prevent the discharge of incompatible pollutants. In that event, such person shall provide at his expense such pretreatment or processing facilities as may be determined necessary to render wastes acceptable for admission to the sanitary sewers.
[Code 1992, § 13.52(8); amended 3-13-2017 by Ord. No. 17-04]
Grease, oil and sand interceptors shall be provided when, in the opinion of the Utility Commission, they are necessary for the proper handling of liquid wastes containing floatable grease in amounts in excess of those specified in this article, or any flammable wastes, sand or other harmful ingredients. 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 City and shall be located as to be readily and easily accessible for cleaning and inspection. In maintaining these interceptors, the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Director of Utilities. Disposal of the collected materials performed by the owner's personnel or currently licensed waste disposal firms shall be in accordance with currently acceptable DNR rules and regulations.
[Code 1992, § 13.52(9); amended 3-13-2017 by Ord. No. 17-04]
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this article shall be determined in accordance with the latest edition of Standard Methods and with the federal regulations, 40 CFR 136, Guidelines Establishing Test Procedures for Analysis of Pollutants, as amended from time to time. Sampling methods, location, time, durations and frequencies are to be determined on an individual basis, subject to approval by the City.
[Code 1992, § 13.52(10); amended 3-13-2017 by Ord. No. 17-04]
Plans, specifications and any other pertinent information relating to proposed flow equalization, pretreatment or grease and/or sand interceptor facilities shall be submitted for review and approval of the Director of Utilities prior to the start of their construction if the effluent from such facilities is to be discharged into the public sewers. No construction of such facilities shall commence until such approval has been granted.
[Code 1992, § 13.52(11); amended 3-13-2017 by Ord. No. 17-04]
Any fees that are incurred by the Utility Commission for review of plans and specifications, compliance reports, operational reports or other analysis and any costs associated with taking and analyzing samples shall be the responsibility of the person discharging the waste. The Director of Utilities or his or her designee will advise the owner regarding the anticipated fees prior to the performance of the work. Any such fees incurred and not paid shall become a lien upon the property upon which such services were rendered.
