No person shall discharge or cause to be discharged
any stormwater, surface water, ground water, roof runoff, subsurface
drainage, uncontaminated cooling water or unpolluted industrial process
waters to any sanitary sewer.
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designed as
combined sewers or storm sewers, or to a natural outlet approved by
the Superintendent. Industrial cooling water or unpolluted process
water may be discharged, on approval of the Superintendent, to a storm
sewer or natural outlet.
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, 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 mg/liter as CN in the wastes as discharged to the
public sewer.
C. Any waters or wastes having a pH lower than 5.5, or
having any other corrosive property capable of causing damage or hazard
to structures, equipment and personnel of the sewage works.
D. Solid and 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, paint, plastics, wood, unground garbage,
whole blood, paunch manure, hair and fleshings, entrails and paper
dishes, cups, milk containers and so forth, either whole or ground
by garbage grinders.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Plumbing Inspector, 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 Plumbing Inspector, and shall be located
as to be readily and easily accessible for cleaning and inspection.
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 expense.
When required by the Plumbing Inspector, 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 Plumbing
Inspector. 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.
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 edition
of "Standard Methods for the Examination of Water and Waste Water,"
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 server 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 sewage works and to determine the existence of hazards to life,
limb, and property. The particular analyses involved will determine
whether a twenty-four-hour composite of all outfalls of a premise
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-hour composites of all outfalls, whereas pH's are
determined from periodic grab samples.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Village and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Village for
treatment, subject to payment therefor by the industrial concern.
