No person shall discharge or cause to be discharged
any unpolluted waters such as stormwater, groundwater, roof runoff,
subsurface drainage or cooling water to any sewer, except stormwater
runoff from limited areas, which stormwater may be polluted at times
and may be discharged to the sanitary sewer by permission of the Superintendent.
Stormwater other than that exempted under §
75-27 and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers or to a natural outlet approved by the Superintendent and other regulatory agencies. Unpolluted industrial cooling water or process waters may be discharged, on approval of the Superintendent, to a storm sewer, combined sewer or natural outlet.
Every user of a public sewer system who has
any storm, surface or foundation drainage, or any wastes from a sump
pump, already entering or part of any existing private sewage which
is to be connected to a public sewer system shall disconnect such
pipes, spouts and/or drains so as to preclude all such waters from
entering the public sewer system and shall thereafter provide other
means to remove such waters away from their buildings.
No person shall discharge or cause to be discharged
any of the following-described waters or wastes to any public sewers:
A. Any gasoline, benzene, naphtha, fuel oil or other
flammable or explosive liquid, solid or gas.
B. Any waters containing toxic or poisonous solids, liquids
or gases in sufficient quantity, either singly or by interaction with
other wastes, to interfere with any waste treatment process, constitute
a hazard to humans or animals, create a public nuisance or create
any hazard in the receiving waters of the wastewater treatment plant.
No person shall discharge or cause to be discharged any waters or
wastes containing a toxic or poisonous substance, a high chlorine
demand or suspended solids in sufficient quantity to injure or interfere
with any sewage treatment process, constitute a hazard to humans or
animals or create any hazard in the receiving waters or the effluent
of the Village sewage treatment plant. Such toxic substances shall
be limited to the average concentrations listed hereinafter in the
sewage as it arrives at the treatment plant, and at no time shall
the hourly concentration at the sewage treatment plant exceed three
times the average concentration. For any waste entering the treatment
plant and containing a combination of chromium (hexavalent), copper,
nickel and zinc, the total concentration of these substances shall
not exceed 10 parts per million. If concentrations listed are exceeded,
individual establishments will be subject to control in volume and
concentration by the Village Engineer.

C. Any waters or wastes having a pH lower than 5.5 or
having any other corrosive property capable of causing damage or hazard
to structures, equipment and personnel of wastewater works.
D. Solid or viscous substances in quantities or of such
size capable of causing obstruction to 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, etc., either whole or ground
up by garbage grinders.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in §
75-31B(3) or any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling 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. In the maintaining of these interceptors, the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Superintendent. Any removal and hauling of the collected materials not performed by the owners' personnel must be performed by currently licensed waste disposal firms.
Where pretreatment or flow-equalizing facilities
are provided or required 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 Superintendent, the owner
of any property serviced by a building sewer carrying industrial wastes
shall install a suitable structure, together with such necessary meters
and other appurtenances in the building sewer to facilitate observation,
sampling and measurement of the wastes. Such structure, when required,
shall be accessible and safely located and shall be constructed in
accordance with plans approved by the Superintendent. The structure
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.
The Superintendent may require a user of sewer
services to provide information needed to determine compliance with
this chapter. These requirements may include:
A. Wastewaters discharge peak rate and volume over a
specified time period.
B. Chemical analyses of wastewaters.
C. Information on raw materials, processes and products
affecting wastewater volume and quality.
D. Quantity and disposition of specific liquid, sludge,
oil, solvent or other materials important to sewer use control.
E. A plot plan of sewers of the user's property, showing
sewer and pretreatment facility locations.
F. Details of wastewater pretreatment facilities.
G. Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
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. Sampling methods, locations,
times, durations and frequencies are to be determined on an individual
basis subject to approval by the Superintendent.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Village and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Village for
treatment.
