No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, cooling water
or unpolluted industrial process waters to any public sanitary sewer.
Where subsoil drains are placed under the cellar floor or used to encircle
the outer walls of a building, the same shall be made of open-jointed drain
tile or earthenware pipe, not less than four inches in diameter, and shall
be properly trapped and protected against back-pressure by an automatic back-pressure
valve accessibly located before entering the house sewer or drain. Such drains
may be discharged through a cellar drain only to storm drain systems or a
natural drainage area.
Stormwater and all other unpolluted drainage shall be discharged to
specifically designated storm drains, or to a natural outlet approved in writing
by the Town. Industrial cooling water or unpolluted process waters may be
discharged to a storm drain or natural outlet upon written approval of the
Board.
Any person responsible for or becoming aware of the discharge to a public
sewer, accidental or otherwise, of any prohibited substance or of any slug
as defined herein shall report same immediately by telephone to the Town so
that necessary precautions can be taken to minimize the deleterious effects
of the discharge.
Where installed, all grease, oil and sand interceptors shall be maintained
by the owner, at his expense, in continuously efficient operation at all times.
When required by the Board, the owner of any property served by a building
sewer carrying industrial wastes shall install a suitable control manhole
in the building sewer to facilitate observation, sampling and measurement
and monitoring of wastes. Such manhole, when required, shall be accessible
and safely located, and shall be constructed in accordance with plans approved
by the Board. 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
industries discharging into a public sewer shall perform such monitoring of
their discharges as the Board and/or other duly authorized employees of the
Town may reasonably require, including installation, use and maintenance of
monitoring equipment, keeping records, and reporting the results of such monitoring
to the Board. Such records shall be made available upon request by the Board
to other agencies having jurisdiction over discharges to the receiving waters.
Where preliminary treatment facilities are provided for any waters or
wastes, the owner at his expense shall maintain them continuously in satisfactory
and effective operation.
All measurements, tests and analyses of the characteristics of waters
and wastes to which reference is made in §
164-28 of this article
shall be determined in accordance with the latest edition of Standard Methods
for the Examination of Water and Wastewater and shall be determined at the
control manhole provided for in §
164-33, 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.
All applications to discharge any industrial wastewater, drainage, substances,
or wastes directly into any sewer under the control of the Town or tributary
thereto shall be accompanied by an agreement stating that the applicant agrees
to abide by all ordinances and rules and regulations of the Town, that the
applicant will provide such works for the preliminary treatment of the wastewater,
drainage, substances or wastes as may be required by the Town, and that the
applicant will permit duly authorized representatives of the Town to enter
the premises of the industry to sample and measure wastewaters, as needed
to check characteristics of the wastewaters, when so directed by the Town.
Applications are to be accompanied by a plan showing essential characteristics
of all wastewater outlets, analyses of existing wastewater, and statements
as to existing and expected average and maximum wastewater flows, and must
be submitted to and approved by the Town prior to initiating discharge into
facilities of the Town. Required wastewater analyses are listed in Article
V.
Each industrial user may be required to submit an annual report on the
first of July each year, or such other time as designated by the Town, to
the Town containing information as to the minimum, average, and peak flows
of industrial wastewater discharges during the previous year and at times
designated by the Town, accompanied by designated analyses of wastewater samplings
taken in an acceptable manner at approved times during the flow measuring
periods.
No statement contained in this article shall be construed as preventing
any special agreement or agreement between the Town and any industrial concern
whereby an industrial waste of unusual strength or character may be accepted
by the Town for treatment, subject to payment therefor by the industrial concern.
