[Code 1999 §710.210; CC 1979 §160.261; Ord. No. 232 Art. V, 4-6-1970]
No person shall discharge or cause to be discharged any storm
water, surface water, ground water, roof runoff, subsurface drainage,
uncontaminated cooling water, or unpolluted industrial process waters
to any sanitary sewer.
[Code 1999 §710.220; CC 1979 §160.262; Ord. No. 232 Art. V, 4-6-1970]
Storm water and all other unpolluted drainage shall be discharged
to such sewers as are specifically designated as combined sewers or
storm sewers, or to a natural outlet approved by the City Sewer Superintendent.
Industrial cooling water or unpolluted process waters may be discharged
on approval of the City Sewer Superintendent to a storm sewer, combined
sewer, or natural outlet.
[Code 1999 §710.230; CC 1979 §160.263; Ord. No. 232 Art. V, 4-6-1970]
A.
No
person shall discharge or cause to be discharged any of the following
described waters or wastes to any public sewers:
1.
Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive
liquid, solid, or gas.
2.
Any waters or wastes containing toxic or poisonous solids, liquids,
or gases in sufficient quantity, either singly or by interaction with
other wastes, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance,
or create any hazard in the receiving waters of the sewage treatment
plant, including, but not limited to, cyanides in excess of two (2)
mg/l as CN in the wastes as discharged to the public sewer.
3.
Any waters or wastes having a pH lower than five and one-half (5.5),
or having any other corrosive property capable of causing damage or
hazard to structures, equipment, and personnel of the sewage works.
4.
Solid or viscous substances in quantities or of such size capable
of causing obstructions to the flow in sewers, or other interference
with the proper operation of the sewage works such as, but not limited
to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags,
feathers, tar, plastics, woods, unground garbage, whole blood, paunch
manure, hair and fleshings, entrails and paper dishes, cups, milk
containers, etc., either whole or ground by garbage grinders.
[Code 1999 §710.240; CC 1979 §160.264; Ord. No. 232 Art. V, 4-6-1970]
A.
No
person shall discharge or cause to be discharged the following described
substances, materials, waters, or wastes if it appears likely in the
opinion of the City Sewer Superintendent that such wastes can harm
either the sewers, sewage treatment process, or equipment, have an
adverse effect on the receiving stream, or can otherwise endanger
life, limb, public property, or constitute a nuisance. In forming
his/her opinion as to the acceptability of these wastes, the City
Sewer Superintendent will give consideration to such factors as the
quantities of subject wastes in relation to flows and velocities in
the sewers, materials of construction of the sewers, nature of the
sewage treatment process, capacity of the sewage treatment plant,
and other pertinent factors. The substances prohibited are:
1.
Any liquid or vapor having a temperature higher than one hundred
fifty degrees Fahrenheit (150°F) (sixty-five degrees Centigrade
(65°C)).
2.
Any water or waste containing fats, wax, grease, or oils, whether
emulsified or not, in excess of one hundred (100) mg/l or containing
substances which may solidify or become viscous at temperatures between
thirty-two degrees Fahrenheit (32°F) and one hundred fifty degrees
Fahrenheit (150°F) (sixty-five degrees Centigrade (65°C)).
3.
Any garbage that has not been properly shredded.
4.
Any waters or wastes containing phenols or other taste- or odor-producing
substances, in such concentration exceeding limits which may be established
by the City Sewer Superintendent as necessary, after treatment of
the composite sewage to meet the requirements of the State, Federal,
or other public agencies or jurisdiction of such discharge to the
receiving waters.
5.
Any waters or wastes having a pH in excess of nine (9.0).
6.
Materials which exert or cause:
a.
Unusual concentration of inert suspended solids (such as, but not
limited to, Fuller's earth, lime slurries, and lime residues) or of
dissolved solids (such as, but not limited to, sodium chloride and
sodium sulfate).
b.
Excessive discoloration (such as, but not limited to, dye wastes
and vegetable tanning solution).
7.
Waters or wastes containing substances which are not amenable to
treatment or reduction by the sewage treatment processes employed,
or are amenable to treatment only to such degree that the sewage treatment
plant effluent cannot meet the requirements of other agencies having
jurisdiction over discharge to the receiving waters.
[Code 1999 §710.250; CC 1979 §160.265; Ord. No. 232 Art. V, 4-6-1970]
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 Section 710.240 of this Chapter, and which in the judgment of the City Sewer 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 City Sewer Superintendent 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, and/or
4.
Require payment to cover the added cost of handling and treating
the wastes not covered by existing taxes or sewer charges.
B.
If
the City Sewer Superintendent permits the pretreatment or equalization
of waste flows, the design and installation of the plants and equipment
shall be subject to the review and approval of the City Sewer Superintendent
and subject to the requirements of all applicable codes, ordinances
and laws.
C.
No
statement contained in this Chapter 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 therefore,
by the industrial concern.
[Code 1999 §710.260; CC 1979 §160.266; Ord. No. 232 Art. V, 4-6-1970]
Grease, oil and sand interceptors shall be provided when, in
the opinion of the City Sewer 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 City Sewer Superintendent and shall be located
as to be readily and easily accessible for cleaning and inspection.
[Code 1999 §710.270; CC 1979 §160.267; Ord. No. 232 Art. V, 4-6-1970]
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.
[Code 1999 §710.280; CC 1979 §160.268; Ord. No. 232 Art. V, 4-6-1970]
When required by the City Sewer 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 accessible and safely located and shall be
constructed in accordance with plans approved by the City Sewer 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.
[Code 1999 §710.290; CC 1979 §160.269; Ord. No. 232 Art. V, 4-6-1970]
All measurements, tests, and analyses of the characteristics
of waters and wastes to which reference is made in this Chapter shall
be determined in accordance with the latest addition 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. 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. 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 to 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.)
