waters.
[R.O. 1996 § 705.250; Code 1985,
§ 110.470; CC 1990 § 20-91]
A. If 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 Sections
705.210 through
705.240 of this Chapter and which in the judgment of the Superintendent 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 Superintendent may:
2.
Require pretreatment to an acceptable
condition for discharge to the public sewers;
3.
Require control over the quantities
and rates of discharge; and/or
4.
Require payment to cover the added costs of handling and treating wastes not covered by existing taxes or sewer charges under the provisions of Subsection
(B) of this Section;
5.
Terminate all utility services as provided in Section
700.070.

codes, ordinances and laws.
[R.O. 1996 § 705.260; Code 1985,
§ 110.480; CC 1990 § 20-92]
Grease, oil and sand interceptors
shall be provided when, in the opinion of the Superintendent, 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 Superintendent and shall
be located as to be readily and easily accessible for cleaning and
inspection.
[R.O. 1996 § 705.270; Code 1985,
§ 110.490; CC 1990 § 20-93]
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/her expense.
[R.O. 1996 § 705.280; Code 1985,
§ 110.500; CC 1990 § 20-94]
When required by the Superintendent,
the owner of any property serviced 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 Superintendent.
The manhole shall be installed by the owner at his/her expense and
shall be maintained by him/her so as to be safe and accessible at
all times.
[R.O. 1996 § 705.290; Code 1985,
§ 110.510; CC 1990 § 20-95]
All measurements, tests and analyses
of the characteristics of water and wastes to which reference is made
in this Article shall be determined in accordance with the latest
edition of "Standard Methods for the Examination of Water and Wastewater"
published by the American Public Health Association and shall be determined
at the control manhole provided, or upon suitable samples taken at
said control manhole. If no special manhole has been required, the
control 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 of life, limb and property. The particular
analyses involved will determine whether a twenty-four (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 are obtained from twenty-four (24) hour composites
of all outfalls, whereas pHs are determined from periodic grab samples.
[R.O. 1996 § 705.300; Code 1985,
§ 110.520; CC 1990 § 20-96]
Nothing in this Article 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.
