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.
Stormwater 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 Superintendent. Industrial cooling
water or unpolluted process waters may be discharged, on approval of the Superintendent,
to a storm sewer, combined 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 milligrams per 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 or viscous substances in such quantities or of
such size as to be 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, entrails and paper dishes, cups, milk containers,
etc., either whole or ground by garbage grinders.
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 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 locked
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.
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 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 analysis involved will
determine whether a twenty-four-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-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.
