No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, sump pump discharge, 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 storm sewers or to
a natural outlet approved by the Town Engineer. Industrial cooling
water or unpolluted process waters may be discharged, on approval
of the Town Engineer and the granting of a discharge permit by the
State Department of Energy and Environmental Protection, to a storm
sewer or natural outlet.
If any waters or wastes discharged or proposed to be discharged to sewers discharging to the sewage treatment plant contain the substances or possess the characteristics enumerated in §
345-44, and which in the judgment of the Superintendent may have a deleterious effect upon the sewage works, processed equipment or receiving waters, or which otherwise create a hazard to life and constitute a public nuisance, the Superintendent may:
B. Require pretreatment and adequate equipment necessary to render the
wastes acceptable for discharge to the sewers;
C. Require control over the quantities; and/or
D. Require payment to cover the added cost of handling and treating
the wastes.
Grease, oil and sand interceptors shall be provided by the owner
at his expense when, in the opinion of the Superintendent, they are
necessary for the proper handling of liquid wastes containing grease
in excessive amounts or any flammable wastes, sand or other harmful
ingredients, except that such interceptors shall not be required for
private living units. All interceptors shall be of a type and capacity
approved by the Superintendent and shall be located as to be readily
and easily accessible for cleaning and inspection.
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 Town, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters or other appurtenances in the building sewer to facilitate observation, sampling and measurement of wastes. An approved valve or gate shall be provided in the manhole to prevent the industrial waste from being discharged into the Town sewage system if it becomes necessary for the Superintendent to reject this industrial waste in accordance with §
345-45. Such manholes, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the Town. 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, Inc., and shall be determined at the control
manhole provided or upon suitable samples taken at the control manhole.
If 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 the Superintendent with such assistance as necessary
from the industry, using 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.
All industries discharging into a public sewer shall perform
such monitoring of their discharge as the Superintendent or other
duly authorized employee 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 Superintendent.
Such records shall be made available upon request by the Superintendent
to other agencies having jurisdiction over discharges to the receiving
water.
All establishments discharging industrial wastes into the Town
sewage system shall obtain a permit from the Town. The Director of
Public Works shall determine the information required to be included
on the application for such permit. Acceptable average and peak rates
of flow and concentration of pollutants shall be prescribed by the
Superintendent. In no instance shall the flow rate exceed 125 gallons
per minute. Average and peak rates of flow shall be determined at
the applicant's expense by a certified testing laboratory or an established
consultant. All permits shall be valid for a period not to exceed
five years.
No statement contained in this chapter shall be construed as
preventing any special written contractual agreement between any industrial
concern and the Town whereby an industrial waste of unusual strength
or characteristics may be accepted by the Town for treatment, subject
to payment therefor by the industrial concern, provided that such
agreements do not contravene any requirements of existing federal
law and are compatible with any user charge and industrial cost recovery
system in effect. Any such special agreement must be authorized and
approved by the Town Council and the State Department of Energy and
Environmental Protection prior to the initiation of sewage service
to the industrial concern.
