described substances, materials, waters or waste to a public sewer
if it appears likely in the opinion of the 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
opinion as to the acceptability of these wastes, the 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, degree of treatability of
wastes in the sewage treatment plant and other pertinent factors.

water or waste containing fats, wax, grease or oils, whether emulsified
or not, in excess of one hundred (100) mg/1 or containing substances
which may solidify or become viscous at temperatures between thirty-two

garbage that has not been properly shredded. The installation and
operation of any garbage grinder equipped with a motor of three-fourths
(¾) horsepower (0.76 hp metric) or greater shall be subject
to the review and approval of the superintendent.

waters or wastes containing strong acid iron pickling wastes or concentrated
plating solutions whether neutralized or not.

objectionable or toxic substances, or wastes exerting an excessive
chlorine requirement, to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the
limits established by the superintendent for such materials.
(6) Any
waters or wastes containing phenols or other taste producing or odor
producing substances, in such concentrations exceeding limits which
may be established by the superintendent as necessary, after treatment
of the composite sewage, to meet the requirements of the state, federal
or other public agencies of jurisdiction for such discharge to the
receiving waters.
(7) Any
radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the superintendent in compliance
with applicable state or federal regulations.
(8) Any
waters or wastes having a pH in excess of nine point five (9.5).
(9) Materials
which exert or cause:
(A) Unusual concentrations of inert suspended solids (such as, but not
limited to, Fullers 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 solutions).
(C) Unusual B.O.D., chemical oxygen demand or chlorine requirements in
such quantities as to constitute a significant load on the sewage
treatment works.

as defined and understood in the trade.
(10) 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.
(1979 Code of Ordinances, Chapter 19, Sec. 19-24)
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
13.205, 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 cost of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of Section
13.213.
If the 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 superintendent

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.

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 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 premise is appropriate or
whether a grab sample or samples should be taken. Normally, but not
always, B.O.D. and suspended solids analyses are obtained from twenty-four
(24) hour composites of all outfalls whereas pH’s are determined
from periodic grab samples.]
(1979 Code of Ordinances, Chapter 19, Sec. 19-28)
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,
samples 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 expense, and shall be maintained
by him so as to be safe and accessible at all times.
(1979 Code of Ordinances, Chapter 19, Sec. 19-29)
