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 §
229-27 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 system 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 injure or 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.

[Amended 8-7-2006 by L.L.
No. 1-2006]
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, entrail 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 §
229-31B(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 so 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 on the user's property showing sewer and pretreatment
facility location.
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, location, 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.
