No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, uncontaminated
cooling water or unpolluted industrial process waters to any sanitary
sewer. Existing facilities presently connected to the combined sewers
may remain until combined sewers become separated, at which time they
shall be disconnected.
No person shall discharge or cause to be discharged any of the
following described waters or wastes to any public sewers:
A. Any gasoline, benzene, naphtha fuel oil or other flammable or explosive
liquid, solid or gas.
B. Any waters or wastes containing toxic or poisonous solids, liquids
or gases in sufficient quantity. However, the discharge of these may
be accepted conditionally by the County Sewer District.
C. Any waters or wastes having a pH lower than 5.5 or having a pH higher
than 9.5 or having any other corrosive property capable of causing
damage or hazard to structures, equipment and personnel of the sewage
works.
D. Solid or viscous substances in quantities or of such size capable
of causing obstruction 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, wood, unground garbage, whole blood, paunch
manure, hair and fleshings and entrails and paper dishes, cups, milk
containers, etc., either whole or ground by garbage grinders.
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 Village Engineer and/or the Director, 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 Village Engineer
and/or the Director will give consideration to such factors as the
quantities of subject wastes in relation to flows and velocities in
the sewers, the materials of construction of the sewers, the nature
of the sewage treatment process, the capacity of the sewage treatment
plant, the degree of treatability of wastes in the water-pollution
control plant and other pertinent factors. The substances prohibited
in the first instance but subject to review by the Village Engineer
and/or the Director are:
A. Any liquid or vapor having a temperature higher than 150° F.
B. Any water or waste containing fats, wax, grease or oils, whether
emulsified or not, in excess of 100 milligrams per liter or containing
substances which may solidify or become viscous at temperatures between
32° and 150° F.
C. Any garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of 3/4
horsepower or greater shall be subject to the review and approval
of the Village Engineer and/or Director. Not more than 30% of ground
garbage, on the dry basis, shall pass a No. 40 United States standard
sieve.
D. Any waters or wastes containing strong-acid iron-pickling wastes
or concentrated plating solutions, whether neutralized or not.
E. Any water or wastes containing iron, chromium, copper, zinc and similar
objectionable or toxic substances, unless their concentration is reduced
to a point that will not adversely affect any of the biochemical,
chemical or other sewage treatment processes. The concentration in
sewage of any of the toxic substances shall not exceed the concentrations
judged by the Director to be toxic to biological sewage treatment
processes or to the biota of the receiving waters.
F. Any water or wastes containing phenols or other taste- or odor-producing
substances in such concentrations exceeding limits which may be established
by the Director 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.
G. Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Village Engineer or Director
in compliance with applicable state or federal regulations.
H. Materials which exert or cause:
(1) Unusual concentrations 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).
(2) Excessive discoloration (such as but not limited to dye wastes and
vegetable tanning solutions).
(3) Unusual BOD, chemical oxygen demand or chloride requirements in such
quantities as to constitute a significant load on the sewage treatment
works.
(4) Unusual volume of flow or concentration of wastes constituting slugs,
as defined herein.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or process the characteristics enumerated in §
133-26 herein and which, in the judgment of the Village Engineer and/or Director, 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 Village Engineer and/or Director may:
B. Require pretreatment to an acceptable condition for discharge to
the public sewers;
C. Require control over the quantities and rates of discharge; and/or
D. Require payment to cover the added cost of handling and treating
the wastes not covered by existing taxes or sewer charges.
