[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:
(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.
