No person shall cause or permit any stormwater, groundwater,
roof runoff or subsurface water drainage (hereinafter referred to
as "natural water") to be discharged into the public sewer or into
any building drain or building sewer connected to the public sewer,
unless prior approval therefor is granted by the City Engineer, which
approval shall be granted only if necessary for the proper and sanitary
disposal of polluted natural water.
Unless approval for discharge into the public sewer is granted, in the manner provided in § 342-16 hereof, natural water and all other unpolluted drainage shall be discharged to storm sewers or to a natural outlet, subject however, to any required approval by any regulatory official, agency or board, and unpolluted industrial cooling water or processed water may, subject to prior approval of the City Engineer, be similarly discharged to a storm sewer or natural outlet.
No person shall discharge or cause or permit to be discharged
into the public sewer any of the following matters:
A.
Gasoline, benzene, naphtha, fuel oil, or any other flammable or explosive
liquid, solid or gas.
B.
Any waters containing toxic or poisonous solids, liquids or gases
in sufficient quality (either singly or by interaction with other
materials) to injure or interfere with any waste treatment process,
or to constitute a hazard to humans or animals, or to create a public
nuisance, or to create any hazard in the wastewater treatment plant.
C.
Any water or waste having a pH lower than 5.5, or having any other
corrosive property capable of causing damage or hazard to structures,
equipment or personnel of the wastewater treatment plant.
D.
Solid or viscous substances in quantities or of such size as to be
capable of causing obstruction of the flow in sewers or other interference
with the proper operation of the wastewater facilities. such as, but
not limited to, ashes, bones, 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 similar materials.
A.
The substances, materials, waters and waste hereinafter described
in this section may be prohibited by the City Engineer from being
injected into the public sewer or may be permitted into the public
sewer in limited concentrations and quantities, as the City Engineer
may determine.
B.
Such materials shall be discharged into the public sewer only in
concentrations or quantities which will not harm either the sewers
or the wastewater treatment plant or any equipment therein and will
not have an adverse effect on the public sewer and will not otherwise
endanger lives, public health or private or public property.
C.
In fixing limitations of concentrations or quantities of such material
to be discharged into the sewer, the City Engineer shall consider
the quantity of such material in relation to flows and velocities
in the sewers, the material of which the sewers are constructed, the
wastewater treatment process being employed, the capacity of the wastewater
treatment plant, the extent to which the wastewater treatment process
can treat such material, and other factors which the City Engineer
deems pertinent to a consideration of the capacity and ability of
the sewer system to carry and properly treat the material.
D.
If the City Engineer determines that such material cannot be carried
and treated without the adverse effects described above, or without
deleterious effect upon the sewer system, he may refuse to accept
the material within the sewer system, or he may require pretreatment
of the material to convert it to an acceptable condition prior to
discharge into the public sewer.
E.
If proper treatment of such material will require extraordinary or
additional costs or expense beyond that normally involved in carrying
and treating sewerage, the City Engineer may require additional payment
for such material to compensate for such additional cost and expense.
F.
The materials referred to in this section which may be conditionally
admitted to the public sewer include the following:
(1)
Wastewater having a temperature higher than 150° F. (65°
C.).
(2)
Wastewater containing more than 25 milligrams per liter of petroleum
oil, nonbiodegradable cutting oil, or any product of mineral oil origin.
(3)
Wastewater from industrial plants containing floatable oils, fat
or grease.
(4)
Any garbage that has not been properly shredded.
(5)
Any waters or wastes containing iron, chromium, copper, mercury,
zinc, or other heavy metals, or similar objectionable or toxic substances
to such degree that any such material received in the composite wastewater
at the wastewater treatment plant will exceed the limits established
by the City Engineer for such materials.
(6)
Any waters or wastes containing odor-producing substances exceeding
limits which may be established by the City Engineer.
(7)
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the City Engineer in compliance
with applicable state or federal regulations.
(8)
Quantities of flow, concentrations, or both which constitute a slug as defined in Article I of this chapter.
(9)
Waters or wastes containing substances which are not amenable to
treatment or reduction by the wastewater treatment processes employed,
or are amenable to treatment only to such degree that the wastewater
treatment plant effluent cannot meet the requirements of other agencies
having jurisdiction over discharge to the receiving waters.
(10)
Any water or wastes which, by interaction with other waste or
wastes in the public sewer system, release obnoxious gases or odors
from suspended solids which interfere with the collection system,
or create a condition deleterious to structures and to the treatment
process.
A.
In addition to the measures described in § 342-19 hereof, the City Engineer may, when he deems it necessary to do so, in order to provide for the proper handling of potentially dangerous or deleterious materials, require the installation of grease, oil and sand interceptors to limit or prevent the entry into the public sewer of liquid wastes containing floatable grease in excessive amounts or any flammable waste, sand or other harmful or potentially harmful ingredient; provided, however, that such interceptors shall not be required for any one-family house.
B.
All such interceptors shall be of a type and capacity approved by
the City Engineer and shall be so located as to be readily accessible
for cleaning and inspection.
C.
The owner of the premises served by such interceptors shall be responsible
for proper maintenance and cleaning thereof and proper removal and
disposal of material therefrom, which removal may be performed either
by the owner of the premises or employees of such owners, or by persons
licensed by the City Engineer for that purpose.
D.
The owner of the premises shall maintain an accurate record of the
date and means of disposal of such material which shall be open to
inspection by the City Engineer.
Where pretreatment or flow-equalizing facilities are provided
for any waters or wastes, they shall be maintained in satisfactory
and effective operating conditions by the owner at the expense of
the owner.
A.
When required by the City Engineer, the owner of any property serviced
by a building sewer carrying industrial wastes shall install a suitable
structure with necessary meters and other appurtenances, connected
to the building sewer, in order to facilitate observation, sampling
and measurement of wastes prior to their entry into the public sewer.
B.
Such structure, when required by the City Engineer, shall be installed
and maintained by the owner, at the expense of the owner, and shall
be accessible and located and maintained in a safe condition.
A.
All measurements, tests, and analyses of waters and wastes to which
reference is made in this chapter shall be determined and performed
in accordance with the latest edition of Standard Methods for the
Examination of Water and Wastewater, published by the American Public
Health Association, and the timing and frequency of such measurements,
tests and analysis shall be determined in each case by the City Engineer.
B.
Fees shall be charged for such tests and measurements in accordance
with the provisions of this chapter or any other ordinance hereafter
adopted by the Council.
Nothing contained in this chapter shall prohibit the City from
permitting the entry of any particular material into the public sewer,
provided that such material shall have received proper and adequate
pretreatment so that the condition thereof, as it enters the public
sewer, shall not be harmful to the public sewer, and for that purpose
the City may enter into any special agreement or contract with any
property owner to provide for special treatment of any waste or any
waste material prior to its entry into the public sewer.
