Unless the context otherwise requires, the meaning
of terms used in this article shall be as follows:
BOD (DENOTING BIOCHEMICAL OXYGEN DEMAND)

of organic matter under standard laboratory procedure in five days
at 20° C., expressed in milligrams per liter.
BOROUGH
The Borough of Caldwell and, when the context requires, shall
mean its Supervising Engineer or his authorized deputy, agent or representative.
INDUSTRIAL SEWER
The pipe which connects an industrial plant to the public
sanitary sewer.
INDUSTRIAL WASTES
The liquid wastes from industrial manufacturing processes,
trade or business, as distinct from sanitary sewage.
pH
The logarithm of the reciprocal of the weight of hydrogen
ions in grams per liter of solution.
SANITARY SEWAGE
Normal domestic sewage from toilets, baths, showers, wash
bowls and sinks, exclusive of industrial wastes or storm and surface
water and drainage.
SANITARY SEWER
A sewer which carries sanitary sewage and to which storm,
surface and ground waters are not intentionally admitted.
SEWAGE
A combination of the water-carried domestic wastes from residences,
offices, schools, business buildings and institutions.
SEWER
A pipe or conduit for carrying sewage.
SEWERAGE WORKS
All facilities for collecting, pumping, treating and disposing
of sewage.
SLUG
Any discharge (into the sewerage works) of water, sewage
or industrial waste from any single user which in concentration of
any given constituent or in quantity of flow exceeds for any period
of duration longer than 15 minutes more than five times the average
twenty-four-hour concentration or flows during normal operation.
SUSPENDED SOLIDS
Solids that either float on the surface of or are in suspension
in water, sewage or other liquids and which are removable by laboratory
filtering.
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, industrial cooling water, unpolluted
process waters and all other unpolluted drainage shall be discharged
to such sewers as are specifically designated as storm sewers or to
a natural outlet approved by the municipality in which the industrial
plant is located.
No person shall discharge or cause to be discharged
any of the following described waters or wastes to any public sanitary
sewers:
A. Any gasoline, benzene, naphtha, petroleum products,
fuel oil or other flammable or explosive liquid, solid or gas.
B. Any waters or wastes containing toxic or poisonous
solids, liquids or gases which, either singly or by interaction with
other wastes, will injure or interfere with any sewage treatment process
or constitute a hazard to humans or animals or create a public nuisance.
C. Any waters or wastes having a corrosive property capable
of causing damage or hazard to structures, equipment and personnel
of the sewerage works.
D. Solid or viscous substances in quantities, concentrations
or of such size capable of causing obstruction to the flow in sewers
or other interference with the proper operation of the sewerage works,
such as, but not limited to, ashes, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastics, wood, whole blood, paunch
manure, hair and fleshing and entrails; and paper dishes, cups, milk
containers or other paper or plastic containers either whole or ground
by garbage grinders.
No person shall discharge or cause to be discharged
into the public sanitary sewer the following described substances,
materials, waters or wastes if, in the opinion of the Borough of Caldwell,
such wastes may cause damage to the sewers or sewerage works or have
an adverse effect on the receiving stream or can otherwise endanger
life, limb, health, public safety, public property or constitute a
nuisance. Upon notification by the Borough of Caldwell, all persons
shall immediately cease to discharge such substances into the public
sanitary sewer:
A. Any liquid or vapor having a temperature lower than
32° F. or higher than 150° F.
B. Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, or containing substances which may
solidify or become viscous at temperatures between 32° F. and
150° F.
C. Any waters or wastes containing acid, iron, pickling
wastes or concentrated plating solutions, whether neutralized or not.
D. Any waters or wastes containing iron, chromium, copper,
phosphates, zinc or any toxic substances whatsoever.
E. Any waters or wastes containing phenols or other taste
or odor producing substances.
F. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by applicable state
or federal regulations.
G. Materials which exert or cause:
(1) 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).
(2) "Slugs" as defined herein.
H. 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.
Where pretreatment 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 Borough of Caldwell, the
owner of any property serviced by a building sewer carrying industrial
wastes shall install a suitable control manhole, together with such
necessary meters, valves and other appurtenances in the building sewer,
to facilitate observation, sampling and measurement of the wastes.
Said manhole, when required, shall be constructed in accordance with
plans approved by the Borough of Caldwell. 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 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.
If a stoppage occurs in an industrial sewer,
all necessary precautions must be taken to intercept the dislodged
material at the first downstream manhole and remove the same from
the sewer system. This may be accomplished by the use of a metallic
screen or similar device.
In addition to the requirements of §§
190-29 and
190-30, the waste effluent from all industrial plants which are to be treated at the Caldwell Wastewater Treatment Plant must conform with the following characteristics:
