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 into any sanitary sewer.
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designated
as storm drains or to a natural outlet approved by the Township Engineer.
Industrial cooling water or unpolluted process waters may be discharged,
on approval of the Township Engineer, to a storm drain or natural
outlet.
No person shall discharge or cause to be discharged
any of the following waters or wastes to Township sewers or Authority
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 or constitute a 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 sewage works.
C. Any waters or wastes, acid or alkaline in reaction,
having a pH lower than 5.5 or higher than 9.5 or having any otehr
corrosive properties capable of causing damage or hazard to structures,
equipment and personnel of the Township or Authority. Free acids and
alkalis of such wastes must be neutralized to a pH of between 5.5
and 9.5 at all times.
D. Solid or viscous substances in 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 and the like, either whole or ground
by garbage grinders.
E. Overflow, drainage or contents of manure pits, cesspools,
septic tanks or other similar receptacles used to store organic wastes,
excluding holding tanks used explicitly for flow equalization.
F. Drainage or contents of swimming pools.
No person shall discharge or cause to be discharged
the following-described substances, waters or wastes if it appears
likely in the opinion of the Township Engineer or the Authority that
such materials can harm sewers, sewage treatment plant processes or
equipment, have an adverse effect on the receiving stream or otherwise
endanger life, limb and public property or constitute a nuisance.
In determining the acceptability of these wastes, consideration will
be given to such factors as quantity, flows, velocities, materials
of construction of the sewers, sewage treatment processes and other
pertinent factors. The prohibited materials are:
A. Any liquid or vapor having a temperature higher than
150° F. [65° C.].
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° F. and 150° F. [0° and 65° C.].
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 [0.76 horsepower metric] or greater shall
be subject to the review and approval of the Township Engineer.
D. Any waters or wastes containing strong acid iron pickling
wastes or concentrated plating solutions, whether neutralized or not.
E. Any waters or wastes containing iron, chromium, copper,
zinc and similar 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 plant exceeds
the limits established by the Authority for such materials.
F. Any waters or wastes containing phenols or other taste-
or odor-producing substances which, either singly or by interaction
with other wastes, are capable of creating a public nuisance or hazard
to life or of preventing entry into sewers for their maintenance and
repair, or in such concentrations exceeding limits which may be established
by the Authority as necessary, after treatment of the composite sewage,
to meet the requirements of discharge to the receiving waters.
G. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Authority
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 chlorine requirements
in such quantities as to constitute a significant load on the sewage
works.
(4) Unusual volume of flow or concentration of wastes
constituting slugs as defined herein. Such water or wastes, if otherwise
acceptable for admission, shall be retained in a holding tank or tanks
of approved capacity and be released at a rate to provide necessary
distribution and dilution to avoid undue burden and shock load on
the sewage works.
I. 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 discharge
to the receiving waters.
[Amended 5-16-1995 by Ord. No. 1220]
A. Interceptors are required to be installed in each facility, business or commercial establishment generating liquid wastes containing grease, oil, flammable waste, sand, solids or other ingredients which, in the opinion of the Township Engineer, Health Officer, Sanitarian or Code Enforcement Officer, are harmful or which cause any malfunction or stoppage to the building drainage system, public sewer or sewage treatment system or process. All food establishments and laundromats are specifically mandated to provide interceptors. Dry-cleaning establishments shall be required to install interceptors except for those dry-cleaning establishments which use only biodegradable soaps or self contained dry-cleaning units and provide the Township Clerk with a certification to that effect on or before January 1 and July 1 of each calendar year. Such interceptors or traps shall not be required for residential premises. All interceptors or traps shall be of a type and capacity approved by the Township and shall be in compliance with the applicable provisions of Ch.
108, Uniform Construction Codes, and regulations adopted thereunder. Each interceptor shall be so installed that it is readily accessible for cleaning, service and for inspection by the appropriate municipal representative responsible for enforcement.
B. Interceptors shall be maintained in an efficient operating
condition by periodic removal of accumulated grease, scum, oil or
other floating substances and solids deposited in the interceptor.
In any event, periodic removal shall be every month or at more frequent
intervals when required by the Township, and a written record must
be kept of each and every such maintenance procedure by the owner,
occupant or proprietor of the establishment.
C. The enforcement officer shall make an inspection of
each premises required to have an interceptor on a periodic basis.
This inspection shall review the operation and maintenance records
required to be kept by the owner, occupant or proprietor in addition
to inspecting the operation of the unit.
D. If any section, sentence, clause or other portion
of this section or the application thereof to any person or circumstance
shall for any reason be adjudged by a court of competent jurisdiction
to be invalid, such judgment shall not affect, impair or repeal the
remainder of this section or the chapters it amends.
When required by the Township Engineer, the
owner of any property serviced by a building sewer connection carrying
industrial wastes shall install a suitable control manhole, together
with such necessary meters and other appurtenances, in the building
connection to facilitate observation sampling 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 Authority. 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 herein
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 downstream manhole
nearest to the point of connection in the Township or Authority sewer.
Procedures for sampling shall be customarily accepted methods to reflect
the effect of constituents upon the sewage works and to determine
the existence of hazards to persons and property.
No statement contained in this Article shall
be construed as preventing any special agreement or arrangement between
the Township and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Township for
treatment, subject to payment therefor by the industrial concern.
[Amended 10-17-2017 by Ord. No. 1842]
A. Each property
owner shall maintain and be responsible for the proper upkeep, repair
and/or replacement of the building drains and building sewer lateral
from the building located on the property to the point of connection
with the municipal public sewer main, typically located in the center
line of the roadway or public right-of-way.
B. In the
event of a blockage, the property owner shall be responsible to immediately
clear the blockage or retain a private contractor, at its sole cost
and expense, to clean the building sewer lateral, regardless of the
cause of the blockage.
C. The property
owner shall further be responsible for cleaning and sanitizing all
areas which may have been contaminated by sewage as a result of their
building sewer lateral blockage, whether on private or public property.
D. Every
owner, occupant or person having charge and control of property within
the Township shall be responsible for the proper installation, repair,
maintenance and upkeep of all connections between their property and
the municipal public sewer main and all connections between their
property and the main storm drain, catch basin or gutter into which
such connections discharge. This responsibility extends up to and
including the actual connection with the public main.
Plumbers shall report to the Township Engineer any known violation of this Part
1 of this chapter, including but not limited to building connections which do not conform to this Part
1 or any other law, rule or regulation.
